Hi, I’ve installed the demo version of Photoshop CS2, but it wont let me create or import any images that use greater than 16-bits!! The "32-bit" option is ghosted out.

This means I can’t open most files, be they 24-bit jpgs or whatever, as a message pops up saying it has trouble decompressing the file. 24-bit bitmaps etc. fail to load, too.

Please help!

I have 2GHz 533MHz PentiumM, 2 x 512mb DDR2 Ram, 256mb nVidia GeForce 6800 graphics, running at a native widescreen LCD resolution of 1440×900 @ 32-bit, using Windows XP Home.

Thanks!

16 bit in this context means 16-bits per colour, not 16 bits total.

24 bits is three 8 bit channels, so you should be fine.

The 32 bit (per channel) option is for HDR images created from multiple images at different exposures, for very wide dynamic range. You can’t create a 32 bit image in PS other than via the HDR creation process. No JPEG will be more than 8 bits/channel.
