COLORS

COLORS, COLORS, COLORS!

Image composition is about light and light is about contrast/brightness and colors. It is either a good idea to surpress as many different colors as possible (resulting in monochromatic pictures when going to the extremes) or to make use of color contrasts by looking for complimentary colors - red, green & blue. The more pure the base color the more extreme is the difference (color contrast) making an image interesting. There're various possibilties to increase color saturation and therefore contrast. Polarizers are the most popular option. These filters work pretty good to enhance the blue sky or shiny objects like the sea or other non-metallic object. The effect is maximized at a position 90 degrees of the sun. Often it is a good idea not to go for the max here. Graduated color filters can help as well here and there. There're also various sorts of direct color enhancers like "Redhancer" filter etc.

Just make sure that you know what you're doing...
