I think I can answer my own question on brightening up my screen. When I took these screen shots I had the surface clarity set to high because most of the water I fish on this lake is around 15 ft or less. I think I still can leave that setting on high most of the time but I had the contrast set to 62% I think If I bump that up to around 80 % That will brighten up the images. I'm having a hard time seeing the screen in the bright sunlight and sepia color seems the brightest to me other than a white background but even with the sepia it's still not easy to see. What are you guys doing to help with that?
