Your best bet would be to work in cocoa and output a tiff
representation of your images at various stages in your pipeline and
then you could see where things have gone awry. This would require
leaving QC however, but you would have more info.
You'd have control over the colorspace of the output files and input
images in your pipeline. What *exactly* does *exact* mean in this
context, for your purposes? The image at some point is going to have
to be interpreted to be displayed...

Subject: Capturing the EXACT output of a CIFilter Patch
Is there any way to capture the EXACT output of a CIFilter patch to
a file? I've managed to solve the the heightmap issue I mentioned at
the end of my last post, but now I'm trying to capture the heightmap
image to a file, so I can use this static image in place of the
CIFilter, saving some cycles.
I've tried placing the output of the CIFilter on a billboard, , then
taking a full-screen screenshot of it. The resulting png file looks
identical to the billboard in QC, but is clearly different, as when
I plug it in to the GL Height Field plugin, instead of getting a
nice sphere as I do when the CIFilter is plugged in, I get one that
is flattened in a few places. I imagine this is some kind of
colorspace and/or color correction issue.
Is there any way of preventing this happening, and capturing exactly
the output of the filter?
I have Photoshop, so I can potentially save out the image in a
variety of different file-formats, is this helps in any way.
Cheers,
alx
