To transform the free graphics program Gimp , picture, or part of it, grayscale, I suggest you read the following article .

2 - Conversion via "Desaturation" : command Desaturation be activated from the menu Colors> Desaturation ... is profoundly different from the command "Grayscale"

• command grayscale transforms any image on which you are currently working in Gimp , including at all levels, the command Desaturation only the active layer.
• command grayscale change the channels Red, Green and Blue destroying them and creating a new gray, from now on any drawing operation on the image will be grayscale, the command keeps desaturation three separate channels, so you can always paint operations of color or recolor it.

Warning: for this method functions, it is selected from the menu Image the RGB mode .
