With Photoshop 2022, working on grayscale images, in psd file foprmats.

When Saving As to jpg file the image sometimes comes out darker and with less contrast.

Why? What can I do?

Do you assess the saved image in Photoshop? does it show up as having an embedded ICC profile?

I hope this helps

To continue, thanks for your efforts!, here is more specifics about my problem:

I edit 16bit grayscale images in Photoshop, saving directly as non flattened .psd files.

Then I also save them as .jpg. Sometimes , not all times, the jpg comes out darker and with less contrast.

This is obvious if I view them side by sideif if in a Bridge preview window,
or if I open both the .psd and the .jpg in Photoshop.

When it happens, it is a big nuiscance. I want to keep the psd as the original and the jpg as a compact to communicate -- and they need to look reasonably the same.

What am I doing wrong?

Why is this so?

Hi

I would trust Photoshop to display correctly in preference to "Bridge"

Do both image documents show up in Photoshop with embedded profiles?

this dialogue at bottom left in Photoshop can show the "Document Profile" as here, I'd imagine yours will show sRGB or Adobe RGB - or, if the embedded profile is the source of the appearance error, it will show "Untagged RGB" which shows there IS no embedded profile.

I hope this helps

Thanks a lot for your good advice and pedagogical efforts on my behalf! I realize I have been very sloppy about profiles. Looking back, I find many of my images are Untagged and very many are dotgain 20%. Thanks to you all I now understand I need to be attentive to the profiles.

I now get Photoshop at opening an image to warn about profile mismatches and I choose to let it assign the current working profile which I now keep set to Gray gamma 2.2. And to save files with that one embedded.

It seems that will solve the problems I have had and which I asked about.

So again, thanks a lot for your help, to raise my understanding about these matters.

The image sometimes comes out darker and with less contrast viewed where? IF not a color managed application, it will not likely match Photoshop (and if it is, it will). We need to know where and how you view the image with less contrast.

Are you embedding the ICC profile in the saved file?

Are you viewing both image files in Photoshop? Beware image viewers that don't use ICC colourmanagment.

If you need greyscale for a particular reason, so be it, but it might be simpler to work in RGB with all channels equal. so that the image is monochrome - as D Fosse wrote, greyscale ICC profiles do not have wide support

I hope this helps

Use Gray Gamma 2.2 or sGray as grayscale profile in Photoshop. Grayscale color management support outside Photoshop is very uncertain, and the PS default dot gain profile will usually not be correctly handled.
