Downside is that the GIMP is still 8-bit, not 24 (32?) bit like Photo$hop, but I get excellent photos regardless. Also, the GIMP has the world's worst user interface. It's difficult to learn; I had to buy "Beginning GIMP" to learn how to do some operations.
Still, it's a powerful package.
It is a beautiful MAC G5 Quad Core 2.5 GHz with 8 gig of RAM.
Cost me a fortune with all of the college software I loaded on it. Ill be darned if he was going to keep it after he blew all of that money on tuition so he could skip classes.
Now all I need to do is learn how to use the software someday. But in the mean time I take pictures and load them to disk.
24 bit is actually 8 bit x 3 colors. GIMP outputs 8(24) bit for normal processsing. It will also output 16 bit for photoshop.
