Red filter?...

What is a red filter for? I screwed it on my camera, and everything looks like nuclear winter, lol. What effects is this for and for what type of situation??? Thanks.

A red filter is generally used for adding contrast in black and white photography.

Besides adding contrast, it will lighten the tone of reds while darkening the tonal values of blues and greens.

The classic example is placing a red apple on a green banana leaf. With no filter the tonality of the leaf and the apple will appear about the same in BW. With a red filter the leaf will look dark, while the apple will lighten. With a green filter the apple will darken while the leaf looks lighter.
