Color in Photoshop differnet than monitor, why?

[clupica]

I have noticed that the colors I see in Photoshop are not the same as the colors I see in PaintShop or in screen wallpaper.

Does anyone know why this is and what is the consequence of the difference? Which colors are "real"? What colors will I get when I send the images off to a photo lab? Does monitor calibration software/hardware help to resolve the differences?

might be different colour spaces..

Saying i^t's the colorspace is a little cryptic if I am unfamilar with the idea of colorspace; which I am only now learning. Could you be more specific.

One of the reasons I bring this up is that I had my Le landeron Image printed (60cm x 91cm)at the local photo store on their large format printer (canon) and the colors were much darker than they appear on my system.

This shook my confidence a little. One set of colors for my screen, another in PhotoShop, and a third for the printout. This is very concerning because I want the send the original off to be printed on a LightJet printer. The cost of a single image is 150.- CHF or around $120. It needs to be right the first time.

i dunno too much either, what i know is that the colour spaces in your printer and in photoshop must be same, i might be wrong..

For sure it's a colour space problem. The simplest way to ensure it will look the same everywhere is to use 'save for web...' from PS. This ensures you're using the sRGB colour space.

There are colour spaces better than sRGB, but I think you'd need a specialist photo lab to be able to handle them.

Going on it being a color space problem, I bought a Spyder2 system so I could do a monitor calibration. After calibrating both of my monitors to use sRGB both seem to be nearly tthe same and the difference between PhotoShop and the screen seems to have disappeared.

I have yet to find out if this helps me when I go off to the photo store to get a super size print made; 61cm X 91cm.

Thanks for the help.

Charles,

in one of the most serious printing lab I know, their printing device colorspace is available for who asks it : you can get it online. You simply have to upload it and proofprint through photoshop.
Try to get it at your printing lab.

Ciao Charlie!
Apart from finding out the colour space they use at the lab, I suppose you have thought of printing a test (a small image or part of the large one) just in case, haven't you? I'm sure the photo lab can help you get the right colours. Good luck anyway!

A complicated subject. I have been browsing http://shop.colourconfidence.com/section.php?xSec=10322 which I think may have some helpful tips in it....photolabs are usually helpful in providing profiles and calibration files.

Hi Charlie. Colour calibration is a many splendoured thing and damn confusing! Have a look at this site. http://www.normankoren.com/makingfineprints1A.html#gammachart It has a downloadable gamma check and test print. It may be that the printers who are to do your work are Pros and possibly using the CMYK space. The absolute best thing you can do is to ask them what colour space to save the image in.
