Hi Sarah,
i decided to buy this programme earlier on this year - think it cost me about £40 - downloaded it off website. Any photos that are pretty close up of people (portraits/wedding photos) i put through this to sort out the face and skin tone pretty easily using sliders to enhance certain features. Only thing i do find is that it some times goes a bit over the top with the shape of the face when it first shows you the amended photo, but this can all be adjusted with sliders (i usually set the face shape sliders to zero or pretty low figures or it changes the look of the person a bit too much (unless thats what you intend to do-lol!).
there was a trial on their website you can download to show u what it can do - you cant save the enhanced photo on the trial which you can do on the full prog-but you can have a go at several different photos but just not save them (think i did about 5 before i decided to buy it).
It saves on having to learn the variety of enhancement tools on photoshop - the programe does all that for you once you have selected the eyes, nose and chin.
On the whole i found that it was money well spent!
