Perhaps you like to use keywords to index or sort your library. Maybe you like to see only those photos taken with a particular model camera … like your film camera? Digital cameras record information about the image captured in the form of a series of EXIF tags (Camera, Lens, Aperture, Exposure etc). It’s these tags that applications like Picasa, Lightroom and Aperture read when importing your images. Scanners apply EXIF data to the images resulting from scans. Film cameras do not (with some rare exceptions) record EXIF data so you’ll need to create it. So here you are, seeking to add EXIF data to your scanned images.
Since Adobe’s Lightroom and most of the other tools that I use are geared towards DSLRs, I have felt the need to add as much EXIF data to my scanned images as possible. The more photos I add to Lightroom, the more important Smart Collections are getting to me and the less I want to rely on keywords. Things become even more complicated when I started using more than one film camera and wanted to use the standard ways to sort my photos by camera. Besides, I have this blog and display my photos online, my visitors want to inspect the EXIF data to get a feel for how I arrived at a particular exposure.
If you have googled how to update EXIF data in an image and you have landed here … you have probably also come across the ExifTool by Phil Harvey. This tool can do everything and more, but in the end it is a Perl script with a command line interface. What was needed was a graphical user interface to the ExifTool and Bogdan Hrastnik has stepped up and developed the ExifToolGUI Windows tool for which you can find all information here. Strongly recommended!
After a little bit of time spent in the ‘Newbie’ stream of the ExifToolGUI forums I worked out how to alter the EXIF data of my scanned film images to reflect the Camera and Lens used to capture the image. Voila! Best of all I can modify the files as a batch. Since my images were already in Lightroom, I selected the images in the Library view, right-clicked them and selected ‘Metadata > Read metadata from files‘ to refresh the image tags reported within the library.
