Hola, alguna razón por la cuál al desaturar una imagen no llega totalmente a tonos grises sino a cafés? 

 

Gracias

    Arturo, please post your questions only once. Duplicate threads cause a lot of confusion.

     

    Yes, it's a CMYK file and that's the explanation.

        @Arturo25633297gm2a – I was going to ask the same thing as @Ranjisha Sengupta:

         

        Are you working in CMYK mode? This can also happen in RGB mode, but is more common in CMYK mode.

         

        Desaturation is for RGB mode and for use with idealised working spaces where R=G=B (not device working spaces).

          Hi there,

          Thanks for reaching out. Let's try to figure out what's going wrong here.

          Which version of Photoshop and macOS are you using? Are you working on CMYK or RGB?

          Does it happen with all of your images? Can you share a sample file with us?

           

          We have a similar discussion on our forum, it's an old post, but you might have a look:  https://community.adobe.com/t5/photoshop-ecosystem-discussions/gray-turns-light-brown-on-cmyk/m-p/9208727

           

          We're here to help, just need some more details.

           

          Thanks.

          Ranjisha

            Thank you very much Ranjisha.

            Even though there is already an answer I still don´t have the solution to the problem. 

             

            The version I´m working with is 22.0 (I had problems with the latest version and the only way to solve them was installing and earlier version), my computer is a Lenovo legion 5 pro with windows 11. I´m working with a CMYK file and I´ve read the old post so I know have an idea of the problem and perhaps a few ways to fix it, however and the main reason I still think I don´t have THE solution is because in a few years working on similar plataforms I never had this issue before, even in CMYK. 

             

            I´ll share a sample file with the CMYK color space. What makes me wonder is that the file can open gray images (as the one in the middle), but if I desaturate that same image or another one with color with the hue/saturation tool the brownish grays appear.    

             

            Thank you

            The explanation was posted in the OP's duplicate thread. It's very simple: CMYK inks - that's the actual, physical inks - don't have equal intensity. You need more C than M or Y to get a neutral tone.

             

            A CMYK color space is not a synthetic/generic color space. A CMYK profile corresponds to an actual printing process - an offset press calibrated to a certain standard, using a certain set of inks on certain paper stock. It describes a real, physical printing process. It's where the rubber hits the road, so to speak.


            Thank you D Fosse. I understand the explanation, but is there any way to simply use the hue/saturation tool like I used to even in CMYK files? As well as why in a past version of PS I could see grays in CMYK and now that changed? If not, could you please tell me what is or how can I know the correct amount of CMYK to create a neutral gray thats proportional to the gray I would get if I desaturate with the hue/saturation tool in another color space?  

             

            Thank you
