I was extremely impressed with this software - after playing with it for 5 hours that is: this is absolutely NOT something you can pick up and play: even the simplest tasks are tricky to get used to; but once you do its fantastic.
I wanted to make a funny card with my friends faces pasted over the heads of a football team: after a few plays, disasters and re-loads, it looks fantastic.
My personal favourite "trick" is removing the backgrounds from images with one just two or three clicks: want a bright blue sky behind a photo of you on a cloudy day? No problem: dont want the white halo you usually get when chopping photos and copying onto a new background? You can eliminate that too with yet another 2 clicks. I think if you figured out all the tools you could probably knock up some "magazine" quality photo-edits; you can do the standard photo shop stuff of getting rid of red-eye - but you can also remove grey hairs, freckles, whiten teeth or rub out a specific area in a photo and have it look pristine and untouched.
Of course this inspired me to then dig out some old photographs that had become damaged over time: you know, scratches, creases, torn corners: just scan them in and the software cleans them right up and makes them look good as new.
Now, the reason I dropped a star is that the potential of the software is, for most people, going to remain untouched: why? Because the manual is literally an inch thick with nearly 400 pages of size 8 font type: thats a LOT to wade through if you dont want to professionally use this software. The "help" system I found very unintuitive and dificult to fathom: you type in a help topic as per most software, but unfortunately the help assumes you already know enough about editing to skip over certain parts - it took me about an hour of trial and error to fix my problem instead: fair enough I got there, but I know a lot of people would be put off with this.
Also its not immediately clear (again, a series of faffing) that if you want to use a part of an edited photo (ie something you want to delete a background from and put on a card etc) you have to export it; you cant just save it and assume it'll behave like a normal jpeg.
In short - fantastic for the pro - I mean a really awesome tool - but for someone like me who just wants to brighten up photos or restore tatty old ones - maybe a more user friendly manual or help guide is in order.
