P: Flat-Field-Correction doesn’t work

[Jeremy Pan]

Recently I updated my Lightroom Classic on my MacMini M1 from 11.31 to 11.4, then I found that the flat-field correction does not acctully work anymore. (I use Leica M240 with SuperAngulon 21mm) 

I did that step by step for many times, I could click the button and the loading bar also run, but the photos changed nothing. I reinstalled the version 11.31 today and it worked, then I tried to install version 11.4 and it didn't work again. So I think it might be a bug of 11.4 either on all computers or on Mac.

Exactly the same situation for me on 11.4

Rollback to 11.31 solved the issue.

And, honestly, I wish Adobe would just let me select a flatfield image, rather than their weird AI guessing which one I'm trying to use.

Same here. The problem is both on Mac and PC.

Recently, I updated my Lightroom Classic on my M1 Max Mac Studio from 11.3.1 to 11.4.1, then I found that the flat-field correction does not actually work anymore. It is creating .dng files but without any correction.

I reinstalled the version 11.3.1 today and it worked, then I tried to install version 11.4 and 11.4.1 and it didn't work again. So I think it might be a bug of 11.4 and 11.4.1. I tried it on both PC and Mac and it's the same.

Per Adobe, your flat-field calibration frame needs to be the first or last photo in your selection. Is it?

Having the same issue as in this post:

P: Flat-Field-Correction doesn’t work - Adobe Support Community - 13031479

It looks like the thread or ticket on this one was closed without considering this as an actual error.

I've tried it myself. On LR Classic 11.5 the Flat-Field Correction doesn't work anymore.

My exact workflow worked on 11.3 and earlier.

When I use the feature, LR creates a new .dng file, but without any correction in it. Comparing the original RAW file with the "corrected" .dng shows that there was no modification done in any way.

Adobe - please look into this and fix this bug that came with 11.4 or 11.5

I just upgraded to 11.5 and exact same issue. It creates a DNG, but otherwise the file remains unchanged.

Flat-field correction is just straight broken.

[risottto]

yes same here, absolutely identical DNG and RAW after falt field correction is applied in 11.5. WHY OH WHY ADOBE MUST YOU BREAK THINGS COMPLETELY FOR NO REASON AT ALL!!!???

Thank you for your patience.

it still doens't work on Lightroom Classic 12.0.

Rikk Said the issue was fixed in 12 (Finally!!??), however is seems like another bug was added in the process. I managed to get a succesfull flat-field working (same pair of images as when I did it in 11.31) , but now there are random rectanges in the DNG that are still present when the file is exported!
