| Re: Quick CS3 Experiment Hi Chris,
I made an error and now everything makes sense.
It should have read as follows:
Try this as an experiment:
1) Open any file in RGB mode.
2) Image | Duplicate
3) Shift Drag one image to the other. The Shift ensures "pin registration."
4) Use blend mode Difference for the second (top) layer.
5) Flatten the file so that only one, top layer remains, the black layer.
6) Use Control M for curves on the top layer. Do you see slight differences between the two pictures when you adjust the curves? My guess is that now you see no difference. That is, Photoshop does produce identical files.
I just discovered my error. Thank you Chris for helping me.
Best regards,
