sRGB exports darker / workaround

Hello--

after looking for solutions yet again for sRGB exports being about one stop darker (and the standard "calibrate your monitor" circular non-solutions) I did notice that exporting the jpeg while the image is set to "soft proofing" for sRGB exports it correctly. The resulting jpeg looks exactly as it does in Lightroom.

note: turning on soft proofing set to sRGB shows no visible change to the picture on screen.

So the question is why doesn't the export dialog do the exact same thing? (if there is a way to automate this / add the soft proof step to the export, please let me know)

What operating system do you use?

And in what application are you viewing the exported jpgs? If it is not color managed, you cannot expect images to display the same as in Lightroom.

the standard "calibrate your monitor" circular non-solutions

If you are concerned about correct colors, you should calibrate with a hardware calibrator, which will create a new, accurate monitor profile. But only color managed applications use the monitor profile, so applications without color management are unaffected.

Soft proofing has no effect on the exported image, it's only a preview of what the image will look like with a particular profile. It's designed primarily to be used with printer profiles to get an idea of what the image will look like when printed.

Yes, if soft proof alters the data themselves, it is user error. Soft proof is a visual, on-screen check for gamut clipping in the proof profile. Anything within gamut is, and should be, unaffected.

This is almost certainly a combination of an incorrect/defective/corrupt monitor profile, and viewing in non-color managed applications that just ignore the profile.

Calibrating and profiling the monitor is indeed the solution, and calling it otherwise just shows a lack of understanding.

Sigh. I'll need to work on isolating the problem more, I wish I hadn't deleted the bad output files--

but: I do use hardware calibrated monitors; I do have fresh profiles; I do view the pictures in color-managed applications (unless Photoshop is not considered one), and I've seen this happen on both Windows and my iMac.

I also don't do anything complicated with the pictures, they are simple Adobe RGB files that get exported as sRGB. The darkened exports don't even seem to be a consistent thing, but are very much noticable when they happen. Yesterday I had to lighten every file by a stop to export properly. After toggling the soft proofing on / off, they seem to be exporting ok at the moment.

This is extremely strange. The soft proofing setting has nothing to do with the export path and in no way is involved with that.

Can you post some screenshots of this problem? What the image looks like in Develop/Library and an export shown in Photoshop.

If you are getting exports that are much darker than the image appears in Lightroom, there are a few things that can happen to cause this. One is possible if you have very large amounts of noise in the images. Think starry sky shots at high ISO or other kinds of night photography. What can happen in those cases is that the display in Develop does not accurately represent the noise in the final output and exports can appear both lighter or darker depending on the export settings (scaling and sharpening basically) and the app that you use to view the image which can use different scaling algorithms to scale the image. Photoshop for example uses two different scaling algorithms based on whether the zoom ratio is a power of two (i.e. 25%, 50%, etc.) or something in between (33%, etc.) which radically changes the appearance of the image if you have a lot of fine detail or noise.

Lastly, lots of strange problems in Lightroom are fixed by resetting its preference file. The preference file gets corrupted much to easily and if it is it causes very strange behavior, so that is something to try.

The images are virtually noiseless; shot in daylight at ISO 200, so it's not that... it seems to be something with specifically going from Adobe RGB to sRGB.

The next time it happens, I'll definitely save all the images and post-- this is why I was also baffled by soft proofing fixing it when other things didn't work (and why I posted on here if it helps someone else with the same problem).

I have a similar issue as well. Here is a screen shot. The image on the right is from within Lightroom (I labeled it wrong), but the "export to .jpg and viewed in Chrome" shows it to be darker and muddier. I always thought that chrome was color managed, but apparently not. Still though, it's very annoying to send images off to clients that seem too dark.

I'm on MAC OSX with an external color calibrated external monitor.

Thanks.

Try the tests here: https://cameratico.com/tools/web-browser-color-management-test/

It appears Chrome may not be correctly color manged on OSX...awaiting an update? Try Safari and compare it against Chrome.

Lightroom is color managed. So every other color managed application should match what you see in LR if at the same zoom level (100%/1:1) AND when viewed in Develop module which is unique in how it previews images from the other modules. IF there is a miss match, the likely cause is the 'other' application not being color managed. Common on Windows.

The other factor can be the display profile IF that other application is known to be color managed. Recalibrate and build a new ICC profile, the older one might be corrupted. Also set the software to only create a Version 2, not Version 4 ICC profile. That's usually configured in preferences within the calibration software. Lastly, if none of the above works, try turning OFF GPU settings in LR's preferences. But in most cases, the mismatch is due to the secondary software not being color managed. Saving as sRGB absolutely does NOT fix this issue! Non color managed applications do not know what sRGB is, do not utilize the display profile etc.

Having exactly the same trouble here. Since I changed Nikon camera settings to Adobe RGB instead of the standard sRGB I experience the same darkening. The preview of LR looks normal and than LR shows the RAW file and it gets about one stop darker. It also shows in the histogram...

 

Can't figure out how to slove it on already imported photo and future photos. I think about going back to sRGB.

Bye.

Chrome on Mac is indeed color managed and does support v2 and v4 profiles. What you are seeing here is therefore likely the result of a v4 icc profile as digital dog suggests as Lightroom has problems with those.
