I just got used to Photoshop CS3 when it expired. There were a few features I used constantly that I can't seem to find comparable options on GIMP.
1. Ability to crop according to aspect ratio. You simply type in the dimensions you want and your rectangle or square for cropping sticks to that ratio.
2. Ability to custom convert to B and W by controlling the different colors with sliders.
3. The ability to fade the picture.
Please let me know if there are plug-ins for these features, or if not, is there any other program that has them?
