Underwater Photography Magazine (UwP), a free PDF magazine, has published a review of MarineLife Keywords written by Alex. The review can be found in their 50th issue, which is available as a free download from their website. Alex says:
The list includes the genus and species of 12,000 species, including over 4,000 fish, 4,000 invertebrates, and all known marine turtles, rays, skates, marine reptiles, and marine mammals... The first thing I did was to try to find any absentees. It is not easy. The coverage is fantastic...
... keywording is an essential part of workflow for anyone who supplies their images to photo stock libraries. MLKL was built for these tasks and having tasted it I could never give it up.
It is often said that time is money. I can't think of many other products, designed for underwater photographers, which will save you as much time for so little money. A highly recommended purchase.
