BACKGROUND
Without planning ahead regarding the likelihood that I would want to isolate all my Black and White photos, over the past several years (as a re-print was needed) I have scanned (or photographed) black and white photos into my computer files in chronologically-labeled folders. Since I gave no forethought to retrieval, both the original date and the digitized date in EXIF are the same.

I now have the need to identify and print some of those that were taken in the 1960s. Since I have digitized only a few hundred, I thought the easiest way to find those few hundreds scattered across about 10,000 mostly colored ones would be to search for only the black and white photos and review each one.

Is there an easy way to search and find those black and white photos?
