Saving for the web
Jun 4, 2022 12:07:08 #
I am not sure if this is the right place to ask this question, but here goes.
I had finished making adjustments to an image and exported the image via "save for the web" as an sRGB jpeg file for purposes of posting on this sight. It seemed to me the exported jpeg when downloaded to the HOG was a bit darker than the original in photoshop. I decided to then save the downloaded jpeg back to my computer then open in Photoshop and check the highlight values as compared to the original. Low and behold, in order to get the same values as viewed in Adobe Camera raw, the jpeg imaged needed to be brightened 1/2 stop to obtain the same values as the original. IMO, 1/2 stop can be significant if you are trying to make the best presentation possible. My question therefore is: is this to be anticipated when saving to the web and should I include in my post processing technique steps to account for the loss of light. Appreciate any constructive feedback you folks be willing to volunteer. Thanks, Nalu

Can't help you but am also interested in this issue.

The Save for Web should simply purge a bunch of the EXIF and identification data. After that action, everything else, including the file format, the pixel resolution, and the colorspace, are matters of the photographer's configuration of the panel settings before the <Save>.
Regarding your observed difference, we can all guess, or you can post and store the two actual JPEGs. I'd expect to see a subtle difference in the actual colorspace -- something you control -- , but that's a guess pending the actual files.

Please post both images and ID the original.

When asking for both images, original and the saved as sRGB, what file format would you suggest for the original?

You saved a JPEG for web. Noted an issue. Then compared to another JPEG. Those would be the two to post for review and comparison, those being the two where a difference was noted.

So the original has not gone through any saving process." Those would be the two to post for review and comparison, those being the two where a difference was noted.
So, how are you suggesting I present the original?

I mentioned the 2nd JPEG as what I thought I'd read the first time, that you had saved two output JPEGs. Glancing again, it seems I misread what was being compared. Let's start with the darker JPEG and see if presents enough information, the saved for web version.
What is your edit colorspace in PS?

I am currently in sRGB. I made the assumption that I was in Adobe RGB 1998. Perhaps that could be an issue.

I think the colorspace is going to be the issue. What you've described is the same uncalibrated colorspace coming out of PS we see at least once every single day on UHH. I've given up making unsolicited offers of help when I see it. Now only getting involved when someone asks why their images don't look right.

Thank you. I don't know how I got to sRGB because I assume that is not the default from Adobe. Somewhere along the line I probably changed it. I will make the change and see if that helps when "exporting to the web". Appreciate the time and suggestions. Have a great weekend. Time to get away from your computer and get out with your camera so we can see some more of your great images and presentations. I may ring you back if I continue to see the same issues. Thanks again.

good. I worked in the yard for almost 3 hours this morning, so I'm still resting before the next project this afternoon ...

Spring not only means nesting and singing birds, but also lawn mowing and planting. Good luck with the garden!

Appreciate your feedback. I'm think Paul's suggestions did the trick, but again, thanks for the offer to help.

Nalu, you are not the problem. I had the same issue with jpg's in general and UHH in particular. I deal with it by routinely increasing the exposure on the final picture by 2/3 stop. You can do this either in Library mode or syncing all of them in Develop.
Good question, good discussion.
