With color film or video, a graduated neutral-density filter can achieve a similar effect, as can a polarizing filter. Using either of these filters can limit camera movement during a shot, as the axis of a graduated filter must match the horizon, and the effect of the polarizing filter changes as the axis of the camera lens moves relative to ...
The streetlight effect, or the drunkard's search principle, is a type of observational bias that occurs when people only search for something where it is easiest to look.

The degree of overexposure depends on the film and the camera used, as well as their different dynamic features. [7] These characteristics are particularly important for portrait photography, in which an extra flash is often used to balance the light on the face or other parts of the body and to soften contrasting shadows in order to properly ...
In some cases, ambient light may be used as a fill, in which case additional lighting provides the stronger light source, for example in bounce flash photography. The relative intensity of ambient light and fill light is known as the lighting ratio , an important factor in calculating contrast in the finished image.
For example, prosthetic makeup can be used to make an actor look like a non-human creature. Optical effects (also called photographic effects) are techniques in which images or film frames are created photographically, either "in-camera" using multiple exposures, mattes, or the Schüfftan process or in post-production using an optical printer ...
The in-camera effect is defined by the fact that the effect exists on the original camera negative or video recording before it is sent to a lab or modified. Effects that modify the original negative at the lab, such as skip bleach or flashing, are not included. Some examples of in-camera effects include the following: Matte painting
