9. Color.

Color does not only evoke an emotional response by a picture-viewer, it also conveys a certain mood associated with it.

Kodachrome film is known for its vibrant red color, and this is exactly the choice of film for this photo of the tropical flower that I shot at the Bush Gardens in Florida, having the Minolta camera's shutter set at 1/60 and apperture at f.8.

The hot colors such as red, orange and yellow tend to be visually strong evoking and relating to fire, sand, summer, sunlight, heat, body warmth etc.

Visually strong colors evoke certain feelings associated with tropical exoticism. Even if your composition is lacking strength, color itself could be capable of giving the strength to your picture.

Cold colors such as white, blue and green, on contrary, tend to be associated with cold, coolness and even freshness -- winter, ice and water, all convey atmosphere of the cold weather by introducing cold, moody, pale and dark colors.

The bluish-greens of the water in this photo of the outdoorsy scene below and yellowish hues of the tops of the trees provoke a viewer to associate this scene with the cool weather of Autumn.

Not only bright, exotic, vibrant, vivid and contrasty colors, but also moody, muted, dark, pale, subtle and harmonious colors could add to the mood of your picture as here below when I photographed San Franciso's China Town during a hazy afternoon.

When your subject is boring, color can revive the photograph. Often colors in your photos depend upon the type of film you use. For example, Polaroid instant picture colors are very unique and exotic, as well as they are different.
