Cyan doesn't work correctly

[ayksep]

Hello, as I want to convert RGB to CMYK I followed all the instructions given here in this video; https://www.youtube.com/watch?v=1A0Aaoy1...=emb_title
However, when I save as .jpg and .tif and open those images again in GIMP they both look different, and when I check the image properties it is still RGB.

First one is the original photo, the second one is the one saved as .jpg and the third is .tif.

And also I tried to save as .psd as instructed in the video there is not a problem saving it as .psd but when I open it looks completely black.

I hope I could figure this out, I want to print out my oil paintings so apparently, CMYK is the only way to do it properly. Thank you.

You have not quite understood that Gimp is 100% RGB editor. Open any supported (color) file in Gimp and it uses RGB colorspace.  RGB images can use a wider gamut - more shades of color than CMYk which is why some colours - bright greens for example - are muted when converted. Open that CMYK image up in Gimp, the image is RGB but those bright colours from the original image are gone.

The Gimp developers always trying to improve Gimp and that does happen now with a Gimp made .psd file. Why I do not know. In earlier versions of Gimp a CMYK image would not open.  To check the file in Gimp, use Cyan again to open it and convert to RGB.

Are you sure that is the only way? Most printers these days will accept an RGB image and if required convert to CMYK with a warning that colours will change. Just the same as the colours change using Cyan.  Some printers use RGB color Laser Printers that produce wonderful quality prints. No need for any conversion.  You need to ask your printing company.
