CYMK TIFF File
I entered this photography contest and they want entries submitted in CYMK TIFF form, however, when I convert my images in PS CS3 to CYMK, the colors change...is this normal and expected?.

Thank you!.

Yes, this is because CYMK (which is used normally for commercial printing) has got a lower gamut or range than RGB so the image is "clipped" to the CMYK range..

Normally you would ask the printer for their colour profile to get the best result and this depends too on which country/continent you are. In PS instead of converting straight from Image > Mode > RGB > CMYK, go to Edit > Convert to Profile and see which one applies for you. Depending on which version of PS you are it should have different profiles for different country/continent..

Once you've converted, do a soft proof as well...

Why would they want a CYMK image? Doesn't make much sense..

The contest is to have to have your photo printed in a book..

The printers used for those purpose work with CYMK color..

People have no clue as to the intricacies of color seperation. When you convert to CYMK, you are assigning various part of CYM to make Black - That in addition to the use of true black. To do this properly you have to know the final destination, i.e. what printer will actually be used. What paper, etc, etc. This is a very big subject and it wouldn't surprise me if your greens come out pink, and your grays, chartruse.

But I'd make sure the contest isn't one of those scams where every photo submitted 'wins'... on the provision that you ordered a copy of the book. This whole thing smells fishy to me...
