it is very very cool - fully automatic capable +haaas solid options for manual adjustment and manual control. BUT, it have nothing to do with good pics -- 'target market'for this soft is bad blurry aged low-res photos. Here Topaz produce some real magik. One of my most happy finds for the last two years - and the one I can use on a daily basis. But thats cause I deal with low-res pictures I get from other side; my own photos I process in PS. ;)
...i.e., a typical user case: if you lost your original photo and left only with , say, 900px preview -- Topaz may help you to restore it in the most easy and intelligent way. (But, of course, it has some limitations as well).
Thanks for your visit, have a Hive !PIZZA my friend.
