Question to profesional CMYK'ers about out Gumut dealing.

[SeniorS]

It's always problem to CMYK nice RGB image because of gamut.
Generally it isn't big problem or it isn't so noticable so personally i leave it as it goes. But sometimes it become a real problem.
And i always wanted to ask some profesional CMYK'er - how they dealing with it?

i haven't any good consistent method. Just play with curves till more or less satisfied or not satisfied but just start to not care anymore. Not best solution, of course.

Here is some random examples from web (got no images with problem right now but when they apear it's kinda too late to ask and at next time get in that troble i wonder why i still haven't asked for help...and so on and on over a years )

RGB-CMYK



As you see shadow/light lost, some details too.

Maybe someone know method to keep details, shadow/light gradient.
Smart, smooth way to deal with that?


P.S. Those anemones sometimes are worst than a rose. And saturated grass goes to plain green to.

I'm not sure what the question is here.
If you're sending your work to a commercial offset printer you use CMYK, otherwise it should stay stay RGB.

Thanks Steve but...looks like i didn't correctly formulate my question

Situation: something like in examples NEEDs to be CMYK'ed (for offset).
Question: better way to avoid out of gamut problems. Especially with something like anemone.

 

[Steve]

See if this helps.

Thanks Steve again.

That helped a little. With anemone that trick don't work so good because almost all of it is out of gamut and described method use desaturation, and with this flower it have to be all desaturated.
But with litle experiment (blending mode for Hue/Saturation) result was better than just converting.

P.S. still not satisfied with outcome of anemone but it definetly gets better
At least details showed up.
just CMYK'ed vs Hue/Saturation (blending mode: Luminosity

I change my mind,- it helped a lot.
Just need little practice. Afterall, all is needed is preserve details, dealing with color can be done later if there is something to deal with.

That's great.
That's what I want to hear.
