Digital photographs - labeling and preserving


         Hope everyone had wonderful holidays and stayed warm. Did you make lots of archival memories?  Now is the time to organize and preserve them.  With the advent of digital photography, especially with it now available on phones, people are taking more and more photographs.  Digital photographs are great in a lot of ways, but to preserve them for the future can be a headache.  The problem, of course, is the rapid changing technology that impacts accessibility. In the digital archival program in which I am involved we save our photographs in TIFF (Tagged Image File Format) format.  That’s pretty much the industry standard because it is supported by most graphic related applications.  Also importantly TIFF has less loss in terms of image quality compared to JPEG (named for the Joint Photographic Expert Group).  The downside is the large size of files.  For my personal use, I save my photographs as JPEGs just because of file size.  If I were a professional photographer I would save my files as TIFFs.  Current thought is that TIFF files will be supported the longest by software applications.  We’ll see. 

        One thing I would suggest is specific labeling.  In my digital archives, we have extensive metadata templates for our collections because some will be downloaded and used for research.  For the individual, simple labeling to provide easy identification of the photograph is probably adequate.  Since you don’t have the back of a photograph to label, you will need to incorporate that information into the picture title. The software dates the photograph or at least when the photograph was downloaded so that takes care of that.  Most programs let you add a specific date if you want.  Location where the image was taken, people, or a title for the photograph is really necessary.  How else are you going to identify the one picture you want from the 10,000 you took of family this holiday season? Most software programs let you organize your photographs by groups and so forth.  Do it!  Otherwise you are going to end up with the equivalent of box of unidentified photographs.  Pretty worthless for memories and for preservation.  Oh yes, and delete those photographs that are out of focus, cut people’s heads off, or are duplicates.  Believe me deleting bad photographs is ok, really it is.  Your descendents and any archivist will thank you.

         Oh yes, make back-ups of your favorites- on the cloud, external hard drives - and keep your photos updated so they can be read by whatever is current in software applications. Most important! That means watching for software updates.  Estimates are that updates to saved images may need to be made every 3-5 years.

Next time - comments on the preservation and labeling of prints both digital and otherwise and negatives and slides.
