Change Color Balance of a black-white photo

[undenifed]

Hello,

I found colorbalance script by Fred, It work fine but maybe it doesn't work with black and white photo.

My original photo: http://i.imgur.com/TjIo2jH.jpg

I tried to call the script with argument: -c red -a 100 -r midtones

I hope you will understand me, sorry for my bad english.

colorbalance only works for color images, not grayscale. If you want to add color then see

If you just want to adjust the brightness and contrast, then see

Perhaps you can explain more about what you want to do or show and example.
