Many of the conditions of natural light and atmosphere can be worked on very effectively on the computer; they can be modified and even, at times, created from scratch. There are no limits to the amount of adjustment and alteration that can be made digitally to images. The most obvious of these digital techniques are those applied to the sky.
Close to the ground, atmospheric haze, mist and even fog can be poured into a scene, though to be effective the technique calls for a hands-on alteration to detail. These atmospheric conditions are readily imitated by placing a pale gray layer over the image at some degree of opacity, but the skill comes in thickening this with distance from the camera. The usual method is first to create a depth map, tailored to the particular image. These are just some of the possibilities, and if you are inventive – and can spare the time and effort – there are endless ways of tweaking the light.
