[delwedd: Hafan Sain Ffagan]
Os ydych chi wedi bod yn pori’n tudalennau Ymweld ac Addysg yn ddiweddar, mae’n siwr ichi ddod ar draws tudalennau sy’n edrych yn wahanol. O’r 9ed o Ragfyr 2014 ymlaen, rydym am dreialu rhannau o wefan Amgueddfa Cymru ar ei newydd wedd.
Mae angen eich adborth chi arnom ni, i wneud yn siwr ein bod ni’n creu’r tudalennau gorau posibl. Os na weithiodd rhywbeth yn ystod eich ymweliad; os oedd unrhywbeth yn anodd i’w ddefnyddio; unrhyw ran o’r tudalennau’n eich drysu neu wybodaeth yn anodd i’w ganfod; neu os oes unrhyw beth yr hoffech chi ein gweld ni’n ei ddiwygio: rhowch wybod i ni. Wrth gwrs, os oes unrhyw beth ‘rydych chi’n ei hoffi am y tudalennau newydd, mi fyddwn yn falch iawn o glywed gennych hefyd!
Pam diweddaru’r wefan?
Wrth i ni archwilio’r hen wefan, mi ddaethom ni o hyd i sawl ardal yr oeddem ni eisiau eu caboli a’u diweddaru.
Un o’n prif amcanion yw ein bod ni’n cyflenwi’r wybodaeth berthnasol i chi, yn gyflym ac yn ddi-ffws. Rydym ni am wneud hyn trwy wella cynnwys y wefan, symleiddio’r profiad gwe-lywio, a thwtio rywfaint ar y tudalennau.
Ein bwriad yw bod pori’r tudalennau newydd yn brofiad cyfoes, ffresh - a bod y wefan yn gweithio’n dda beth bynnag fo’r dechnoleg - ffôn symudol, llechen, rhaglen darllen sgrîn, neu gyfrifiadur desg. Mae ymweld â saith safle ein hamgueddfeydd yn brofiadau unigryw ac felly gobeithio ein bod ni’n adlewyrchu rhywfaint o hynny ar ein gwefan hefyd.
Dim ond rhai ffyrdd o wella’n gwefan yw’r rhain. Fe fyddwn ni’n gwneud rhagor o waith ar y safle yn yr wythnosau a misoedd sydd i ddod.
O’n blaen yn 2015
Yn ystod hanner cyntaf 2015 mi fyddwn yn diweddaru a chaboli rhagor o ardaloedd y wefan. Bydd tudalennau newydd am ein Casgliadau, ein gwaith curadurol a’n gwasanaethau llogi yn ymddangos, yn ogystal â’r blog a siop ar-lein.
Mi fyddwn ni’n sicrhau fod pob ardal o’r wefan gystal ag y gallith fod, trwy wrando ar, a dysgu gan, ddefnyddwyr ein gwefan.
Bydd eich adborth a’ch mewnbwn chi, felly, yn rhan allweddol o wella’r safle. Dim ond y dechrau yw hyn.
Is Content still King?
Graham Davies, Digital Programmes Manager, Amgueddfa Cymru - National Museum Wales
"Content is King". The phrase is strong, infallible, sitting proud on his pedestal, a little like the Queen Mother, or the National Health Service. Sacrosanct. But has the time come to question some of our long held adages in the world of digital content and web design? Is content actually 'King' anymore?
Fresh back from an energising few days with the fab team at Culture24 at the Let's Get Real workshops and conference, I am determined not to let the enthusiasm and momentum get buried by the squillions of things in my inbox that greet me now that I am not 'Out of Office' anymore.
The discussions of the last few days have left me pondering over our constantly evolving digital landscape.
Which direction, and how high do we have to throw our digital content ball to get it successfully into the constantly moving net of engagement?
Jessica Riches, in her talk on 'Learning from Brands' seemed very surprised that she was the first of the day to mention the phrase ‘Content is King’
This made me think. And think again. About the shift in focus to be more about platforms, the importance of audiences and what channels those audiences use and reside in.
So has the time come to update or even rewrite the rulebook?
1. Content is King?
Surely it's not just raw content that is king anymore. Who your content is intended for significantly alters how it should be written and where it should be published. What is the intent of those people reading it? (as apposed to the intentions of those writing it). So I give you rule rewrite number 1:
Content, Intent and Purpose are the new King, Queen and Jack
By thinking of it this way, you are reminded that content on its own doesn't stand any more. It's equally important to also think of why you are writing it and where the people are who want to read it?
2. Build it and They Will Come?
This fell off its pedestal a long time ago, but if we were to prop it back in place the stonemasons would need to re-carve the plinth to read:
Write it and take it to where they are. Or perhaps better still: Go pay them a visit and have a chat
This helps reinforce the idea that we can't be institutional broadcasters anymore, we should be working with our audience to help them answer what they want to know, rather than what we want to tell them.
To demonstrate this, Shelley Bernstein provided us with a superb keynote speech at the Let's Get Real conference on how the Brooklyn Museum are trusting the audience and developing a wholly user-centric approach to their new responsive museum.
3. Design Responsive Websites
Great, Yes, very good. Although a revision of this phrase can encompass web design by default whilst primarily focussing on content:
Optimise your content to be platform independent
4. Think Mobile First
Yes, we must, and we should make this behaviour ingrained. By turning this rule upside-down, our new banner proclaims (and by its very nature automatically assumes mobile first):
Remember to check the desktop
Think back to those good old days where everything had to be retrofitted to work in IE 6. Who now retrospectively checks that everything reads and works well on a desktop? Not many I'm guessing.
But beware. Herein lies the paradox: Remember, people looking to visit one of our venues are more likely to be looking us up through a mobile device. However, people looking at in-depth long-form curatorial and academic material are predominantly still using desktops.
This is where headline metrics can be misleading, if your website as a whole shows a rise in mobile, that doesn't mean that all the content on the site is being accessed through mobiles. This is why metric analysis is so crucial before we apply blanket statements based on overall trends.
This brings me onto to something bigger I have been mulling over recently...
"Can we put it on the website please"?
Quite frankly, I dislike the term "Website". I often ask what section or area people are actually referring to, for websites these days have come to contain many distinct areas and functions, serving completely separate and different audiences and requirements. Maybe this is the crux of the problem? At the moment we are all busy working on a 'one solution fits all approach'. Shouldn't we be thinking of applying separate templates and content strategies based on different audience requirements within our own websites?
Going back to our rewritten rule number one, and this should be applied within (and throughout) our own organisational websites too.
All this can help us ensure that we consistently put the users needs at the centre of our goals and ambitions. Just by thinking a little differently about our assumptions, we have the ability to take a quicker, more direct route to successful engagement.

I-Spy Micrarium Touch Screen (VADU part II)
There is an exhibition showing at National Museum Cardiff called: I-Spy…Nature (until April 2015). One of the touch screens (picture 1) focuses on a selection of diverse, interesting and beautiful biological and geological slides from the Museum’s Natural History Collections. This blog is about the small aspects of the touch screen that I was involved with; plain and simple.
Resources & Outlines
- One general overview image of 36 slides
- 12 very high resolution images of some of those slides
- 27 inch touch screen
- Complement an actual Micrarium, which would be displayed neatly above the touch screen
- Incorporate a Victoriana style
- Target audience: young folk
All the controls were laid out in plain sight, hopefully to reduce any learning curve when approaching the interactive; and since the touch screen is quite large (27 inches) we had the space.
Five additional features were added to the zoom screen (picture 4):
- Zoom controls
- Navigation controls
- Home button
- Information button
- Change language (English/Welsh)
n.b. where possible I tried to avoid using words to describe button functions, hence why the home button is only an image, but this idea fell down a little when it became clear you couldn’t avoid a word or two to help the visitor work out what specimen they were observing.
Into the Arms of a Microscope
Once or twice someone may have caught me saying things like: “Plagioclase Feldspar” or “Olivine”. Anyhow, part of the fun with looking at slides is the process of selecting a new slide, I thought so anyway - you were never sure what would be on the other side of the glass.
I wanted to avoid the conventional method of changing between images, which is usually to include a ‘next’ and ‘previous’ button; so tried to incorporate some of my vague science memories with a quick reconnaissance mission (picture 5) to see the microscope that was being prepped for the exhibition.
Since there were 36 lower resolution images on the home screen, but twelve high resolution images on the slide selection screen, it gave some space to move a simple microscope stand into view, which provided the excuse to animate the microscope arms and float the slides back and forth. The iris transition between the microscope slide view and the zoom view is loosely based on the idea of looking down a microscope eyepiece.
We’ve been using Firefox for a while as its platform independent and has neat little add-ons (R-Kiosk and Block Site). In this case, the operating system is Windows 7, with a locked down user account which only has access to Firefox and the touch screen drivers.
Usually we use Google Analytics to record button events, to give us an indication of how much the interactives are being used, but Google Analytics is designed to work with regular domain websites, which is not the case when running locally from simple hard drive files. Therefore the button events are recorded by the web server through AJAX calls.
I've included a short demo video for posterity:micrarium_demo.mp4
exciting developments afoot...
After much discussion and background work, the digital team at Amguefdda Cymru today began on the exciting path of redesigning its website.
As well as being timely (it’s been almost 5 years since our last design iteration *gasp*), there are a number of important factors driving this project, including an ambitious digital strategy to help deliver the redevelopment of St. Fagans National History Museum, as well as a comprehensive review of our institutional structure as a result of the Museums Change Programme.
Areas for development in this project will include providing greater access to online collections, increasing digital participation and also integrating today's social networking activities to encourage participation and sharing.
With these drivers in mind, we’ve been busy beavering away in the background over the last few months, researching audiences, analysing metrics, workshoping stakeholders and talking to our users. Why? Quite simply, we want this project to be as ‘evidence led’ as possible - let’s act on what our users tell us, from how they get to our website, to what they do when they get there.
time to put the user at the centre
From all this background research, we have developed a specific list of objectives that our new redesigned website will seek to provide. In summary these are;
- Reflect first and foremost, the needs and interests of our users
- Be focused on individual museum sites and our knowledge, not our corporate brand
- Remove barriers to our information, including language and structure
- Present a clear and logical navigational structure
- Remove redundant sections and pages
- Present a simple, clean design
- Ensure that there are no dead ends for users - always offer an alternative if no exact content matches their search
- provide fresh and routinely updated material
We are now in a position to take stock of our whole online offer: microsites, domains, social media connections, visiting pages, collections pages, even our in-gallery interfaces, while at the same time rethinking our traditional ‘institutional’ view of what we present online.
Most of you in Museum digital circles will know just how easy it is for websites to evolve through a reflection of internal structures. This is our chance to turn that thinking around and apply fresh perspectives, new ideas and modern technology to a website that really works for those visiting our websites - all based on evidence driven research, of course...
Timescale for all this? 8 months, so check back for updates to how this journey unfolds…
The steady march of the mobile device
Graham Davies, Online Curator, Amgeddfa Cymru - National Museum Wales
Access to online content is showing a steady shift towards the mobile device. What are the implications for Amgueddfa Cumry’s own website?
There has been much discussion in the museums digital sector lately on the significant rise in websites accessed via mobile devices. It was one of the focuses of the 'Let's Get Real' Action Research project run by Culture24, of which the Museum was a part. The V&A have recently been publishing their findings on what devices people use to access different areas of their website.
In light of this, I decided to uncover the trends taking place on the National Museum Wales own website: museumwales.ac.uk
Mobile device growth over two years
From the National Museum Wales’ perspective the rate of acces from mobile devices shows pretty much the same pattern reported from other similar institutions.
Overall, we see close to a 25% rise in visits via mobile device to the website over a two year period. This is significant, but applying this as a generalisation of the website as a whole may be hiding other, more significant trends.
Figure 1 shows that people are increasingly looking at our website through mobile devices, but what parts of the site are fuelling this rise? What other trends become apparent when we look at areas such as visiting information, or our content rich collections pages?
So, lets break this down and let's see if we can work out what’s going on here…
What are people mainly looking at when using mobile devices?
A comparison of Figure 2 and Figure 3 clearly show a markedly higher percentage of pages accessed via mobile device to our 'visiting' pages than our content rich Art Online collections pages, (which incidentally show more of a rise in tablet use than mobile.)
What this all boils down to is that our content is now being accessed (and increasingly so) through all manner of different devices, and in all manner of different environments, from coffee shops, trains, your sofa, at work etc., etc.
The devices we choose are driven by the context (or setting) we are in, also the time we have to find out what we need to know. Think about it for a minute. How do you use digital devices to locate and find out information? Sat at a desk in your lunchtime, with time to sift through search results to find local events this coming weekend, filtering and refining on a large screen with a mouse and keyboard. Then there’s that last minute check on opening times and directions on your mobile phone whilst in a crowded train on your Friday night commute, straining to keep your phone viewable whilst jammed up against another person, typing with one finger. Come Sunday evening, you’re lying on the sofa, tablet on lap learning more about that nugget of information you picked up, or writing about your experiance on a review site.
This behaviour is quite logical if we take time to consider user behaviour on different devices, but what does this mean for our website and how we manage it?
What we must ensure when publishing our content is that we understand that the users could be anywhere, doing anything. A the moment, the evidence seems to suggest most mobile access targets visiting and location based information, whereas in depth collections data remains to be largely accessed via desktops.
The decline of the desktop (well, for visiting information at least)
Figure 2 shows that more people are viewing our visiting information from mobile devices than they are from desktops or laptops. It is therefore critical when planning content and designing websites, that areas of the website need to be thought out in separate ways, with visiting and site based information being designed and created first and foremost to be viewed on mobile devices.
In addition to functionality and design, we must also ensure that the content we provide for those areas of the website that are accessed primarily through mobile devices is crystal clear, succinct and quick to discover and understand - after all, you may only have a 5inch screen to get your information across.
Given the rate of growth from mobile devices it will be interesting to see where we will be this time next year...

How more sales can mean less revenue
And they're here: for the first time, we have figures for a year of e-book sales, supplied directly by publishers. It's still far from the whole picture, as not all e-book figures are available. But we now have a much better idea of what the book-buying landscape looks like in the UK.
The figure that stands out is that e-book sales are now up to 13%-14% of all book sales. However, as their prices are cheaper, that's only 6%-7% of revenue. Print book sales are down again, by 3.4% on 2011, as are average prices.
The e-book market is still dominated by fiction, and those e-book figures track the print figures. That is, if a book sells well in print, it also does well in e-book. The stand-out example is a particularly, shall we say, shady trilogy, whose e-book sales are about 36% of the print sales. Could the success of the e-book version of these titles lie, I wonder, in the fact that no-one can see what you're reading on your Kindle...?
So, it's mixed news: more books were bought in 2012, but because more of them were e-books, publishers made less money. Good news for reading, less so for publishing.
Meanwhile, here at Amgueddfa Cymru our journey into 'e' continues...
With thanks to The Bookseller for the sales figures.
New Media, New Challenges
[delwedd: Plasty Margam, Morgannwg, tua'r Gogledd]

Graham Davies, Online Curator, Amgeddfa Cymru - National Museum Wales
Earlier this year I was approached by the Keeper of Art regarding a recent acquisition of two oil paintings dating from 1700. The paintings in question - two large panoramic paintings of Margam House - were purchased with help from the Heritage Lottery Fund and the Art Fund, and as the funding included some form of digital exploration, I was asked to produce an interactive to compliment the gallery display (that would also be available to tour with the paintings).
On closer inspection of the paintings, lot of small, intricate detail became noticeable. As some details were very small - and would benefit from additional interpretation - some sort of zoomable image would offer the visitors with the best form of digital exploration.
In previous gallery interactive developments, the New Media Department have used the iPad2 platform, but as the newer iPad3 has a retina display - a screen resolution and pixel density so high that a person is unable to discern the individual pixels at a normal viewing distance - this platform seemed ideal to explore small detail in high resolution images. As for the software, we decided to use an adaptation of a previously developed interactive that allowed the user to move around a high-resolution image to predetermined hotspots (to explain certain details of the painting).
I then went about locating numerous details on the canvas that would be interesting and informative to the viewer. I was keen to pick things out that would not be contained on the gallery labels, thus ensuring no duplication and offering an enhanced visitor experience.
After obtaining high-resolution images of the two paintings I was able to upload these to our Content Management System (amgeuddfacms), to allow them to be served from our website server. It was at this point that a strange technical inconsistency occurred....
Viewing 3800?pixel wide image on a standard Firefox browser on my desktop screen rendered the image sharp and clear. However, serving the exact same image into the iPad3 web browser rendered a fuzzy pixelated image. Given that the same image was being served to both screens it seemed that the different web browsers were handling the image in a different way.
A little bit of research on the internet revealed the possible problem: The default web browser on an iPad (Safari), runs WebKit which only seems to serve images up to a maximum size (somewhere around 1024 pixels wide). The iPad browser seemed to be downsampling the original 3800 wide image to 1024 wide, before then upscaling this 1024 wide image back up to 3800, causing the image to render at almost 400% it's downsampled 1024 pixel size.
The problem was how to get around this. After some researching on the internet for similar problems, it seemed that there was no conclusive solution. This was mainly due to the logical assumption that it’s bad practice to serve huge images to a website (especially on a mobile device such as an iPad, where web content was readily downloaded via mobile networks), so the advice was always to use small images. Of course we wanted very large images, so this didn’t help!
One solution that Chris Owen, our Web Manager came up with was to serve two halves of the image separately and automatically stitch them back together again after they loaded on the web page - thus the page would load two smaller images. Technically this gave a good result, but cutting the image in half was not enough. We therefore generated a script that sliced the image into 500 by 500 pixels (totaling 64 separate images), and stitched them all back together again once they were loaded into the browser.
The outcome was a high-resolution image (made up of smaller individual images) that renders sharply even when zoomed right in. This gets around the issue of the Safari web browser on an iPad automatically scaling down large images.
Research suggests that this may be a first in application development of this sort, especially one developed wholly in HTML5.
Gesture enhanced interactive
Once this high resolution was served up onto the new iPad3, in high resolution quality, it became clear that it would make more sense to make this a ‘gesture enhanced’ (pinch to zoom) interactive in addition to interpreting predetermined parts of the painting.
This means that the user can now fully explore the entire image, zooming right into any part of the image, whilst being able to read interpretive labels embedded within the image.
The next problem to solve was the one of colour accuracy. Due to the original paintings being very dark, most images that we had to play with were lightened in order to see the detail. This lightening caused the colours to be untrue to the original, something that would be noticeable once screen and canvas were next to each other in the gallery.
A quick phone call to our photography department affirmed that they had high-resolution master TIFF files available that were ‘colour correct’, i.e. the colours in the digital capture were exactly as they were in the painting.
These colour correct images turned out to be strikingly different to the ones that we had previously been playing with, the increased sharpness causing even more detail to become apparent, even figures appeared that weren’t noticeable on the previous images.
The application will be installed alongside the paintings of Margam House in the Art in Wales 1500-1700 gallery at National Museum Cardiff in October 2012.
Bringing it all together: Art in Wales 1550-1700
A parallel development to this in-gallery interactive is a website interactive exploring a major portrait of the builder of Margam House – Sir Thomas Mansel with his wife, Jayne (hung alongside the Margam paintings in Art in Wales 1550-1700 gallery). Again, certain parts of the painting can be explored in high resolution through interpretive labels embedded in the image. This further compliments an existing interactive, exploring another major portrait in the gallery – Katheryn of Berain, the Mother of Wales.
It is hoped to extend this program to include all the items in the gallery, thus forming a holistic digital interpretation of Art in Wales from 1550-1700, available both within the gallery and through the website.
Art Gallery VADU
VADU: Visual Audio Display Unit
My last blog entry was back in April 2009, so this is a hesitant return.
In July 2011 the refurbished Contemporary & Modern Art galleries were re-opened at the National Museum Cardiff, the following VADU would be included in the initial exhibition. The specification was mainly to showcase video shorts: recorded, interviewed and edited by a few of my colleagues (Art and New Media), the videos would have subtitles and also there would be a visitor comments page.
The iPad 2 was about to be launched when I started work on the VADU. Magic was in the air, queues were forming.
Note: it has been used for two exhibitions, so far:
- Contemporary & Modern Art (July 2011 – January 2012)
- The Queen: Art and Image (January 2012 – April 2012)
Although there is an 'App Store', it seemed like overkill to write and release an application simply for four machines in an art gallery - I used 'Kiosk Pro' instead, an application which basically removed all the usual iPad functionality and locked it down to a fullscreen Safari browser.
In regards to the actual design aspect of the VADU interface: the only two constraints were museum brand guidelines and a particular colour had to be used to unify it with the surrounding new gallery signage.
Around May 2011, Braun's designer Dieter Rams design ideas entered my world (I can't repeat his mantra here, but only because it is copyrighted). Anyhow, I tried to create an interface that was simple, intuitive, consistent, and didn't distract the user from the actual content:
- Only two colours
- No drop-shadows or gradients
- 10px borders
- I did allow myself one curvy corner (bottom-right), one guilty pleasure
- User navigation: horizontal gestures only
- Page transitions: vertical only
If you haven't already looked at the photograph 1 and 1b, I would take a look now; so we have a shared reference images in mind.
The top section displays the title of the exhibition, followed by page buttons (Art, Comments and What's On). All exciting stuff - the tip of an arrow indicates which page the user is on (hopefully in a subtle fashion).
The language button starts the most convoluted process on the VADU, in terms of animating a page change. I didn't want the change to be instant, instead I gave it a more graceful flow. The actual result of changing the language only swaps the domain name from English to Welsh or visa-versa (museumwales.ac.uk, amgueddfacymru.ac.uk), but the time it takes to do that is over four seconds. It should become clearer later, if you watch the video below.
The middle section displays the video in focus at the time, large screen print from the video is shown in the background - title, summary and extraneous information such as video length are shown on the information panel. In large font the word: 'Play', indicating the user can start a video. Left and right arrows also allow the user to shuffle through the videos. The information panel can be moved from the right or left of the background image - something that resulted from the fact artists don't like their work flipped [in a digital sense] i.e. if the focus of the background is to the left, the information panel can be positioned to the right by indicating such in the CMS metadata entry.
The bottom section can be dragged with a finger left and right, selecting any one of the sixteen videos. It was quite important to have draggable areas, because it is simply expected by iPad users (thus, making it intuitive). The same draggable feature is used for the what's on page (photograph 6).
If the user selects a video, the screen removes all navigation features so they are only left with the title of the video, a video time indicator (so the user knows the video is only short), the video itself in the center of the screen, the subtitles at the base of the screen and a 'back' button. The user can pause and un-pause the video by tapping of the video in the center (see photograph 3). The video's themselves use the same colour as the VADU, so it all fits together neatly.
Finally the comments page is simple too: optional name input, text input and the last three comments are displayed on the right-hand side (hopefully encouraging the user to write something). The comments are fed into the usual website comments system, approved (or not) by a staff member (photograph 5) – there has been over 2000 comments left of the gallery VADU since July 2011, which is quite a lot considering no one was forcing these people to write something.
The gallery VADUs have been very reliable; once every few months one of them may freeze, but considering they are always on (one weakness of iOS software is you can‘t boot-up into a single application), that's not too bad. I darken the screen after the galleries close – simply using a whole–screen black div.
We had a brief problem when changing the local network settings in January, so I added a check before the VADU changes language to see if there is a network available (an AJAX query: onSuccess or onFailure).
If it continues to be used, I would like to develop a local version of the VADU, providing a fallback if the network goes down, or maybe a hybrid version (storing the videos on the VADU). This would mean a update of the iOS (from 4.3 to 5.1+), but I‘m sure there would be some associated browser performance improvements.
Other major changes shouldn't be required, as the video shorts are meant to be the star of the show.
Obviously it helps to have a pleasant environment to place the VADUs (photograph 9).
I've included a short demo video for posterity:art-gallery-VADU.mp4

Graham Davies, Online Curator, Amgeddfa Cymru - National Museum Wales
When a member of the Art department approached me to ask if I could feature two views of the same painting online — one version covered in dirt and yellowed varnish (as the painting was when it came into the Museum), and the other version showing hidden detail and crisp colours (after being cleaned by Museum conservators) — I realised it would make a perfect interactive if you could use your mouse to virtually 'clean' the dirty canvas to reveal the clean version underneath.
Guardi's view of the Grand Canal, Venice
The painting in question is Francsesco Guardi's View of the Palazzo Loredan dell'Ambasciatore on the Grand Canal, Venice, painted around 1775-85.
Acquired by Amgueddfa Cymru in 2011, this painting is an important acquisition as Guardi's Venetian views are regarded as highly significant in the history of landscape painting.
You clean the painting
To make the most out of this dramatic before and after view, I needed to work out a way of 'virtually' cleaning the painting online by dragging a mouse over the dirty image to reveal the original details and colours previously hidden underneath the dirt and old varnish.
Reinvent the wheel?
I wanted something that allowed the mouse to act as an eraser; allowing one image to be rubbed out to reveal a secondary image underneath. A hunt around the internet brought up the required functionality already created by by Jonathan Nicol (www.f6design.com/journal).
The next step was to acquire high resolution copies of both dirty (before) and cleaned (after) digital images of the artwork from the Photography department.
Precisely aligning two slightly different angled photographs of the same picture
When I opened these digital images in Photohshop it became apparent that variations in the perspective, and distance of the photographic captures resulted in two images that did not precisely match up once overlaid on top of one another.
After an hour of miniscule adjustments using the image warp feature on Photoshop using the images as separate layers within Photoshop (one set at 50% opacity), I eventually achieved a precise overlaid match.
I abandoned trying to do this at 100% view as the image was so large and the time lag in processing too great to view the results (even for my G5 at 2.44Gz and 8GB RAM). I had to settle for a 25% view that filled my Apple 32" screen)
Once I had a satisfactory matched up and aligned the 'dirty' layer on top of the 'clean' layer, I could create the two corresponding TIFF images to incorporate into the Flash file as a basis for the interactive.
After a bit of tweaking, fiddling, and constant testing, I managed to create a simple interactive, allowing you to use your mouse to erase the dirty image, revealing the clean one underneath.
Exploring the detail.
I then decided to repeat this process to create several versions, all using crops of the high resolution images to show close up details of the painting.
Areas of particular interest I choose to separate out were people rowing a goldola, the architectural detail of the buildings, and the detail of the sky and clouds where much original detail had been almost totally obscured by years of grime, dirt and previous 'touch-ups' to the painting. The clean version revealed original intricate details and brushwork.
Future applications for Museum archives and collections
I am hoping this functionality can be utilised for other online images of the collections in the future. Ideas I have at the moment are to reveal hidden under-drawings only visible under x-ray light — as in the example of Richard Wilson's Dolbadarn Castle (NMW A 72), which has been painted over a portrait of a woman, and Landscape with Banditti around a Tent (NMW A 69) which he painted over a Venetian-style reclining nude.
Additional ideas include viewing a landscape or post industrial townscape that can be erased to reveal a historical image underneath...
