I know, I know read the manual...I did, unfortunately I have had very little succes. In avoiding taking a fancy camera course for underwater I'm turning to my Scubaboard Family memebers to help me out. Here it goes; I have the Bonica Snapper XP 3.2 Interpolated 8.0 MP with external strobe. I've taken some pictures and most have come out all white, some blurry, some all black (in a cavern). I also noticed that I have to reset my strobe to work when then camera goes into it's auto shut down. I turn it on and shoot only to realize 100 pictures later that my strobe was not shooting. Some pictures have a yellow aspect to them as well. I'm not sure what speeds to use or when the strobe is most effective. Any tips would be greatly appreciated, sorry to sound so incomplete.
