In my work I use CMYK on daily basis and I think the question "why photos should be retouched in CMYK" is not the right one to ask. One could do that but it's not the point. CMYK is not needed because it's nice to retouch images but because it provides fine control over cyan, magenta, yellow and black color components in four color professional print. One could only relay on color management in print workflow, but oftentimes it's insufficient. There are (not so rare) cases when CMS doesn't yield expected resultsâI mean: conversion can be done all right according to theory but in spite of that it's better to manually decide how some colors end up looking like. Sometimes one need to add or remove some "paint" from reproduction before it's going to be printed. Example: you need to have nice black background. Most of the times CMS will try to simulate that with all colors while it's better to use e.g. just full black and cyan. Another example: you need to do some trapping. Sometimes it can be done in RIP but you need to trust that to RIP itself and print house. These are only a couple of arguments, leaving aside quite similar cases of printing with paints different than C, M, Y and K.
