I've been having a devil of a time with this in Quartz Composer. I wanted to analyze an image, store the information in a buffer, then use that buffer for subsequent iterative processing of the image (why I need to store the information first).
The problem is that the analysis can produce positive and negative numbers (and potentially under -1 or over 1) and Quartz Composer won't leave the values alone EVEN if I calculate them using a GLSL program inside a Render In Image with the flag set to Disable Color Correction. I think it simply clips off the negative values. I tried compressing the range by adding 1 and dividing by 2, but that is less than effective. I also tried the secret preference of turning off correct Core Image. That had no effect, plus I can't guarantee it'll be turned off on another system. Is there ANY way to store a buffer of information and access it later without QC diddling with it when it enters a pipe?
