Photogenics works differently to Image FX.
You use the drawing tools to mark out any area you want to manipulate with an effect. Once marked out, selecting the effect will make that effect visible, but the original image is not permanently altered until you "fix" it. The advantage is that you can spray out the region you want effected with the free hand tool, and then just select a different effect, or alter the parameters of the effect, and the area selected is updated in real time, with the new effect. It is a layers system of sorts, and in many ways its faster than trying to set up layers and masks in photoshop.
Version 2 is easiest to come by these days, but can be a bit unstable. Never was a PPC version.
V4 and V5 had an interface update, but were quite unstable.
You really need a RTG card, but better still IMO is running it on Winuae.
