This isnt a standard digital photo Q but I figured the folks here might have an idea of how to solve this Q. I emailed someone a scanned form, text on white paper. They have filled it in, scanned it, and sent it back to me. I wish to print it off. For some reason, although the original form was white , the returned background of the form is pink. I'd like to remove the pink background before printing. If I print in black and white, its too 'harsh' and you miss some of the text & writing, print in grayscale and the pink comes out as light gray. Ideally I'd just like to change any shade of pink to white. I dont have photoshop. i do have iPhoto, paintbrush. Any ideas?
