Woodland green is another color shift problem that can occur as light filters through translucent leaves. I generally don t find this objectionable, however, I do own a .05 magenta gel that I have used in that situation when shooting white flowers. Since the advent of new warmer films, I seldom see that problem. 82 series filters can be used to render more naturally, the red portions illuminated by a sunset. In a clear sky sunset, the sky separates into a red hemisphere and a blue hemisphere.
Photographers are often so intent on capturing the red, that the rich indigos go unnoticed.
I like to shoot laterally on those days, finding objects that are bathed in red on one half, and shadowed in deep blue on the other half. During sunrise and sunset, these areas are to the North and South. Finally, light can be either diffuse or hard. This attribute is determined by the relative size of the light source. The sun is a point light source and produces hard light with shadows that show sharp edges.
