I did not purchase the program. I tried the trial and then did not purchase. I did not spend enough time to really see how it would work. Instead, I downloaded another program, "Everything". It is a free (donation only) program. It is not a cull or label program. It merely searches and, for my purposes, does a great job. I use Photo Mechanic for culling and I should use it for labeling/keywording, but alas, I only use the culling feature. I name my processed shots with species, location and processing mode, so that is how I search for them with Everything.
