I agree with Jon 110% on this. In addition, there is another
PhotoShop feature which is extremely handy, and which would make a
valuable addition to the GIMP.
In particular, when doing color matching and color correction, it is
useful to try and match in the shadow, midtone, and highlight regions
of the image. PhotoShop allows the user to display the RGB (CMYK)
values in the info window for up to 4 clicked pixels in the image.
This allows the user to experiment with finding appropriate values to
match with out having to write the values down on a piece of paper.
Furthermore, PhotoShop has a *very* useful feature which allows the
user to automatically adjust the curves tool so that the pixel on the
mouse cursor maps to a neutral value. That is, if the RGB value under
the mouse cursor is
RGB = 128 147 132
then the curves are mapped to the value
RGB -> 130 130 130
Here the midpoint of the two closest values (128 and 132) is chosen as
the representative neutral value and the 147 is also mapped to this
point. This too would be of great use in the GIMP.
Finally, as in Photoshop, the Curves tool should also have the
"Automatic" button that exists in the Levels tool.
