Instance Property

contrast

An adjustment factor to apply to the overall visual contrast of the rendered scene.

Declaration

@property(nonatomic) CGFloat contrast;

Discussion

A value of 0.0 (the default) leaves the rendered scene unchanged. Positive values increase contrast between bright and dark areas, and negative values reduce contrast, shifting the rendered scene towards a uniform gray.

To enable this behavior, you must first enable the wantsHDR setting.
