Hi Alex,
Try using Grab to capture your screen if you didn't already. Not cmd-
shift-3 or cmd-shift-4.
I guess it has something to do with the gamut correction on your
display card that's taken into account when you use cmd-shift-3 or 4.
Maybe it is the vcgt tab in your display's colorsync profile. Not
sure however.
Paul.
Anyone?
This is really bugging me...

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
