How do you change the "Color Balance" like in Photoshop?

[floyd]

Hey, I'm new here, so sorry if that question has already been asked/answered somewhere else, but I couldn't find anything on the forum or on Google. I also looked at http://www.imagemagick.org/script/comma ... ptions.php, but I'm not sure what to use in this case? -level-colors, maybe?

So, here is the original image:


And here is what it should end up looking like:


And I used the following settings in PS:


Does anyone know how to do this? Can this even be done with IM without using some other script? Any help will be very much appreciated!

-gamma 1,1.4,.01 produces similar colors although the shuttle is a bit yellow.
-gamma 1,.5,.01 makes a nice image too, looks like taken in sunset

Thanks, Glenn! I guess I'll play around a lil more with -gamma.

If you are on Linux, Mac or Windows w/Cygwin, see my unix bash script, colorbalance, at the link below.

WARNING: this will not likely work in IMv7 due to the use of mutliple channels
Multi-value lists is turned off at the moment, and no I did not do this - cause was underlying library change.
You may need to use -channel to restrict what channel each gamma value affects.

Adding this note IMv7 porting.

IM has -tint. I just created a new script, midtonebalance, to do colorbalance like in PS, but only for midtones.

Would you mind sharing the script? The midtones colorbalance is what I need, your help is appreciated!
