The authors provide a good series of demos about how to use the program. The only problem is that when changes are made in a photo, the file is saved as a proprietary file type, "TPI," so the revised photo cannot be opened using normal graphics software. The FULL program removes that restriction, but costs $29.95! No thank you. Free is supposed to be free...not just a come-on. Shame on the developer. I suppose you might be able to print out the revised photo, but you can't share it with anyone who doesn't have the program installed.
