Multiply in Composite Operation
Multiplies the color component of two input images and creates an output image using the multiplied values. This filter is typically used to add a spotlight or similar lighting effect to an image.
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.
