Film Stock patch comes with Quartz Composer as composition in repository "/System/Library/Graphics/Quartz Composer Patches" more...

Adjusts midtone brightness. This filter is typically used to compensate for nonlinear effects of displays. Adjusting the gamma effectively changes the slope of the transition between black and white. Note that the image produced by this filter may have infinite dimensions. If this is the case, since Quartz Composer doesn't know how to render such images, you will need to convert it to finite dimensions before rendering it - typically using the Image Crop patch. Core Image filters might not produce any ... more...

ASCII Art patch comes with Quartz Composer as composition in repository "/System/Library/Graphics/Quartz Composer Patches" more...

Simulates the dot patterns of a halftone screen. Note that the image produced by this filter may have infinite dimensions. If this is the case, since Quartz Composer doesn't know how to render such images, you will need to convert it to finite dimensions before rendering it - typically using the Image Crop patch. Core Image filters might not produce any image if any of their image inputs are undefined. Be also aware that they expect coordinates expressed in image pixels and not in Quartz Composer units. more...

Dent patch comes with Quartz Composer as composition in repository "/System/Library/Graphics/Quartz Composer Patches" more...

Adjusts saturation, brightness, and contrast values. Note that the image produced by this filter may have infinite dimensions. If this is the case, since Quartz Composer doesn't know how to render such images, you will need to convert it to finite dimensions before rendering it - typically using the Image Crop patch.
