There is, however one common exposure problem I see in fishing photo's. It seems everybody has a favourite fishing hat to keep the sun out of their eyes. This results in a shadow under the brim. Film can't compensate for differences in light and shade the way the human eye can. Fortunately the solution is simple.
Most people make the mistake of using the flash only at night or in the low light.
The flash can't compete with the power of the sun but it will serve to fill in the shadows. You will also be amazed at the way it brightens the colours. The second major component of a good photo is composition. This means arranging the elements in the picture so that they come together to form a whole. The elements you include help to shape the story you are telling.
