can someone please help me choose the right setting in photoshop for printing and uploading my photos. i have had this problem before when having some of my photographs printed in a studio. the colours appeared washed out and i had the developer reprint them to appear like the original images on the disk. am i to understand that this has to do with the file being converted from RGB to CMYK?. after looking on the internet found similar probems and was told to convert my photos to sRGB IEC61966-2.1 using edit, convert to profile in photoshop cs2. however it is still losing some of the intensity when it is uploaded. what am i doing wrong here?

Calibrate your monitor. The "Pantone Huey" and the "Color Vision Spyder" can be hired if you don't want to buy or the "Spyder2Express" is a budjet solution for around $70.

You probably still need to calibrate. Also there is an image gamma difference between Mac and PC / *nix so they will always look different on a different OS.

Macs generally have a target gamma of 1.8 while Windows and non-Apple *nix have a target of 2.2 or 2.4. The result is that images made on Macs look too dark on everything else and images made on everything else look too light on Macs.

If you still think it's not the monitor then try adjusting the image gamma before printing.

Setting the profile to sRGB IEC61966-2.1 usually solves the problem - I'm not sure why you're still seeing a loss of saturation with this profile. In CS2, are you assigning the profile or converting the profile? You must use "convert to profile", not assiging a profile.

you probably don't want to be using srgb for printing. If you use a particular photo printer you could ask for a copy of their printer profile and assign that to the photos. you should then get a pretty close copy of the shot.
