Always keep the sun over your shoulder when you take fish pictures. Even if you have to position the boat. A picture with the sun shining on the fish will highlight great detail. Great photographs highlight the fish over the fisherman. Most people use digital cameras now. Set the resolution at one of the highest settings, and change the settings for the proper outside/inside location. Try to get out of direct sunlight if possible as this often throws reflections on a wet fish.

Photos allow me to custom paint your fish reproduction. More importantly, we can determine first hand what color phase the fish may be in, and most species vary somewhat by location.
