Lightroom mobile: Unwanted side effects while editing manually distortion corrected DNGs

  • Updated 4 years ago
A problem editing with LR mobile - case as follows:

1.) DNG (pic taken with a fish eye lens) imported in to LR desktop.

2.) Custom lens profile correction applied; custom aspect here is the distortion slider set to 0 (=no distortion correction; default would be 100).

3.) Manual application of the distortion slider to 100 (so the fish eye curves are straightened out);

4.) adding this DNG to a collection synced with LR mobile;

5.) after sync editing this pic within LR mobile - e.g. applying auto color.

6.) Unwanted result in LR mobile: not only the color correction is applied - that is wanted - but also the distortion correction automatically reverts to 0, which is unwanted. The picture has the typical fish eye curves again.

This problem has been reproduced a couple of times.

What happens if you turn off the Enable Profile Corrections at step 2? Does the manual distortion at step 3 shows up in Lr mobile?

I may have been not precise enough. I used manual distortion correction in the "Profile" tab, not in the "Manual" tab of the lens correction box.

If I deactivate "Enable Profile Correction" I can't use the distortion control in the Profil tab; the pic then of course reverts to uncorrected in LR desktop, and that is correctly synced to LR mobile.

Interestingly enough after doing that some times in a row on LR mobile the bug didn't appear any longer for one of the fish eye pics - applying Auto Color correction didn't change distortion in LR mobile any more.

But I have another, non fish eye DNG with lens profile correction activated where the application of Auto Color in LR mobile let's the picture revert to uncorrected (CA correction, vignetting and distortion are clearly visible). Turning lens correction on and off mutltiple times in LR desktop didn't help here. So there definitely is something wrong ...

Another important thing I just checked: the change in the application of lens profile corrections is not synced back to LR desktop - it's only visible in LR mobile. Other changes - like Auto Color - are synced back.

Can you please let us know what you mean by Auto Color in Lr mobile?
Do you mean White balance/Auto or auto tone?

It would be good if you could say exactly which step you are doing in in LrD or LrM.

Btw I've been able to reproduce this, we're now giving this a closer look.

Thanks,

OK, nice to know!

I used Auto Tone (have the German version, so it reads "Auto Farbton", and I just assumed "Auto Color" would be the English equivalent).

Just toyed around with a couple of other non fish eye DNGs with lens profile correction applied in LR desktop - *any* adjustment in the basic panel of LR mobile would make the smart preview loose the lens profile correction, but only the adjustments made in LR mobile are being sync backed to LR desktop, not the loss or deactivation of the lens profiles.

Hi. Could you do me the favor and upload a test DNG (pic taken with your fish eye lens) since I have still trouble to reproduce.

Best would be to use the Command-S before, so that the Develop-Settings are part of the image

Thanks, Guido
