I finally dove with my XZ-1 and twin INON strobes. The viz was very poor and conditions were difficult but the real problem that I noticed was that when taking photos I set exposure to -0.7 and using my strobes in both manual and a combination of ttl and manual, my camera screen was not bright enough to effectively get the job done because of the settings. Without the strobes the pics would have been underexposed and the screen reflected this. The question is, can I set the camera up to not lighten and darken based on perceived exposure?
