No Photo shoots here. I just sourced a few decent images of fish and a forrest scene online. The first step was to edit the fish into the forrest scene in the most realistic way possible. It involved choosing positions and sizes carefully then masking them behind trees for added realism. I then placed several adjustment layers over the whole composition including Grain, Grayscale, Darkness and Levels. I added lights in the fish's eyes by blurring a white paint brush then added highlights/glow to nearby trees.
