This is my first post on this section of the Forum, so please be gentle with me :)
My employer printed wall calendars for 2013 using 12 of my photos, one for each month. This was the first time I had my color photos printed by an ink print process, except for a few individual technical images which were not selected for photographic merit.
To everyone who commented: thank you for your very kind words.
I'd like to add that this was a novel experience for me. Normally, when I present photos to my friends or relatives, I have a free choice of what I want to show. Assembling photos for a calendar was very different. For instance, I wanted to post a photo of mating frogs for April, but the management team thought that there would be too many themes. Eventually we limited the photos to two themes: landscapes (or cityscapes) and birds.
Coping with the ad agency and printer wrt CMYK conversion was a different story altogether. I initially prepared TIF files in Adobe RGB to provide the best possible starting material. But the AD in the advertising agency, who did the CMYK conversion, thought that all photos from amateur photographers are in sRGB, and the initial proofs were desperately in need of more saturation. If there will be a next time, I'll probably try the CMYK conversion myself.
CMYK conversion is straightforward and, when they are your images, much more satisfying than letting someone downstream — or some box downstream — do the conversions.
Generally speaking, while there are various ways and settings to make the conversion, the bottom line is that you are going from a larger color space to a (much) smaller color space. Some images will make the transition unscathed; some with be altered slightly; and some will simply stink in CMYK.
And this is the benefit of you making the conversions: you get to see the color shifts and then tweak as desired. The first round of calendar conversions were no doubt right out of the box. Next time you do them and you'll be much happier!
