One day I was feeling a little more relaxed then normal when I was photoshop color correcting one of my scanned paintings and I diverted off track (which is easy to do when you have a Brain Injury Disability) and I noticed the invert option in PS and guess what I did? I did my first invert of one of my images and voila! There it was. A totally new image with a click of the button. Don't you just love technology!?!
