CMYK is what the pic will look like when printed, it is industry standard for poster and other prints. You therefore need to provide your image - with color correction - in CMYK. I am unsure as to how close to RGB you can get in CMYK even after tweaking but the reality is the picture will ultimately look as the CMYK version when printed. Hope that make sense?

Hi Yohan, Thanks & yes - all understood about the need for CMYK for the printer......I just never had to look at one of MY OWN images in CMYK before and got a shock when I saw what the software had done to it. But that was several days ago - I have a handle on things now...... I just don't look at CMYK images with ACDsee anymore :-) (That particular programme cannot handle CMYK correctly - as far as I can tell).

The attached images (my last post) were just to illustrate the amount of change I could see on my monitor.

Try Irfanview, you can use specific Profile to match what you use in the main Editor program.

Simple and effective, download the plugin pack to open CR2 or other RAW format, not sure about FITS... Great on CR2 to see EXIF

Sorry about not answering your question originally about the software! I wrongfully assume most people using image management software use high profile software like Gimp, Photoshop and similar ones.

Think of the conundrum another way: Would you be sending an RGB or CMYK colour profile image to e.g. Astronomy Now or Sky at Night magazines for print in their pages? Visually, if your image was printed, YOU might see the colour variation from what you expected to see in print, but to the reader, they would not. Being anal (using the term playfully) about colour profiling when making a decision on screen in a vote on an image might not therefore come into it, because you won't actually know what the person who took the image wants the reader to see! You just see a spectacular image.

A great topic of conversation this, thanks for bringing it up Brendan!
