Why can't I open .CR2 or .FIT files in CS3 Photoshop?

[Robert_T]

Hi All, Bluescopes post prompted this question, but I didn't want to jump in there and hijack his thread. I have Photoshop CS3 extended version, but it does not open my canon raw files .CR2 or 32bit FIT files (and possibly others). It "sees" them, but when I go to open it says ...

"could not complete your request because it's the wrong sort of document"

Any ideas... I don't want to lose the full bit range of my data just because of this.

cheers,

Bob

Photoshop will only read 16bit TIFF files at best.
There is a free 16bit FITS plugin :-

Just realised I'm running PS 6, I'm a little out of date

You can get a 40D raw plugin for photoshop - check the adobe site. I think it's called CameraRaw.

thanks guys, I sometimes wonder what I'd do without this site

You can also get the NASA/ESA FITs liberator - free download.

Make sure you run downloads and updates too. With CS2 - it couldn't read Canon RAW files until downloaded and installed a 80mb update!

I don't thing Liberator will help though. CS2 yes, but not CS3. I normally have to convert my Fits to Tiffs, and then use then within CS3.

I use liberator with CS3
