Hello everyone!
Am I doning something wrong or is my eyedropper tool giving me incorrect readings?
Basically when I sample area (hover over an area I want to get reading from) where I know it is clipped shadows, it tells me K=90%. But that should be 100%, no?
When I sample area where I know the highlights are not clipped, it tells me K=0%.
The histogram confirms that there are no clipped highlights and that there are clipped shadows.
It is really strange to me, but perhaps I am using it wrong?
Thanks in advance for your time!
All the best from Prague

You are just reading the K channel. A lot of the tone is in the CMY channels. If you want just the K readout (essentially, merging all the colors) use the Panel Options menu to change our CMYK readout to Grayscale (K only).

Thank you so much, Creamer! It worked.
I knew I am dumb, but now there is a proof on the internet. : D
I was baffled why are there any values in CMY. I thought since it is B/W image there should be only K value. But I've dissmised it as part of the error. Turns out I don't know enough.
Anyway thank you again for your time.
I am off to do some googling on the CMYK topic.

The CMYK values would happen if the image was printed as a 4-color black. This gets into the color management stuff that I won't go into now...
Don't sweat not knowing something. Very few people can claim to know everything there is to know about a program like Photoshop. Many of us, myself included, learn the hard way--messing up, asking for help or looking it up, and remembering it for later.
