I wanted to post this question to the entire forum audience to see what responses I would get.
Recently, among fellow underwater photographers, we debated the importance of a second strobe. While I understand how extra light can be used for illuminating and shadowing effects I wonder if it is really necessary. (Read as:: underwater photographer with a tight budget.) I personally feel that based on the relatively nice dive conditions I experience in South Florida and the Caribbean a second strobe is not necessarily needed.
Any thoughts on the matter?
