Exposure Adjust (Repository Composition) in Other, Filter

Adjusts the exposure setting for an image similar to the way you control exposure for a camera when you change the F-stop.

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.

Input Attributes Image EV

Output Attributes Image - The resulting image.
