Thumbs up on the Kageyama book! Ive been using his techniques for several yrs and bought his light filter. As far as I know this is the first and only definitive work on the topic.

Also Univ of Wisconsin has done research on what fish see.

Does anyone else know of other research taking place on what fish see? thx -j
