You may want to look into purchasing the American Institute for Conservation’s publication, “Guide to Digital Photography and Conservation Documentation.” It is $75 so a bit of an investment but it has good and recent information on camera specs, digital photography file types, Adobe Photoshop, etc. If you are going to be doing more events like this in the future or photographing museum collections, it would be worth the cost.
