Recently, the British Library did a CT Scan of the St. Cuthbert Gospel, one of the oldest European manuscripts, dating to the 8th Century. An explanation of the process of scanning the manuscript can be found on the British Library’s website. Once the manuscript was scanned, along with a facsimile used for comparison, the data was processed in a program called “Drishti,” which allows for exploring and visualizing vast amount of data (above).
From the scans, researchers discovered that the central motif on the binding was made using a clay-like material, rather than gesso or cord as had previously been thought.
The entire manuscript has been digitized and is available on the British Library’s website here.
Have you ever wanted to eliminate the distracting background from an object photographed on-site? Cutting out the background can be very easy or a bit challenging, depending on how complex the image is. The magic wand tool can be a very effective tool when your background is simple in nature.
1. Select the magic wand tool from the toolbar.
2. Click on the area you want to sample. The magic wand will outline the area with flashing dotted lines.
3. Initially, the magic wand may only pick up some of the background. Hold the Shift key and continue clicking on the areas to add to the selection until the object is isolated.
4. Use the Exposure tool to adjust the background to white or black, pulling it to the far right for white or far left for black.
5. You may need to use the clone tool or paintbrush to clean-up areas that the magic wand tool missed.
Are you trying to add labels to maps, charts, drawings, or other images in Photoshop? Are you finding it impossible to change the background color of your text box?
If so, that’s because it is impossible! Photoshop does not have this functionality. There is a workaround, however, if you’d like to continue working with your image in Photoshop:
First, create your text box by selecting the “T” tool from your Photoshop Toolbox.
You can change the size, style, and color of your font from the top menu.
Next, find your Rectangle Tool. It may be hidden behind a tool that looks like a forward slash (/). To switch tools, mouse over the / icon and hit control, then select the Rectangle Tool.
Using the Rectangle Tool, draw a box around your text. You can adjust the color and opacity from the top menu. If you don’t see an option for opacity at top, you can change the opacity from the layer adjustment tools at right.
You can then send the box you made behind the text by going to Layer > Arrange > Send Backward.
By default, each time you create a new object or text box you will create a new layer. You may want to flatten the image periodically, if you know that you won’t be making further adjustments to some boxes/text. You can also learn more about managing your layers in CS6 by viewing this tutorial.
It’s been reported that Mac users are having problems downloading images from the ARTstor Digital Library due to an outdated or deactivated version of Java.
If you are using Apple OSX 10.7 or later, you will need to install the latest version of Java and allow it on your browser. If you are using Mac OXX 10.5 or 10.6 and are unable to download images, Java may have been deactivated, so all you have to do is re-activate it.
If you are encountering problems downloading images from ARTstor and these solutions aren’t helping, please do not hesitate to contact us!

Digital photos, electronic documents, and other new media are fragile and require special care to keep them useable. But preserving digital information is a new concept that most people have little experience with. As new technologies appear for creating and saving our personal digital information, older ones become obsolete, making it difficult to access older content. Learn about the nature of the problem and hear about some simple, practical tips and tools to help you keep your digital memories safe.
As always, if you have any questions about managing your digital images, please contact the VRC.
