Lightroom: 4.1 rc1 - unable to read monochrome Sigma DP X3F files

Sigma DP2s

LR 4.1 rc1

I import .X3F files to LR catalogue from SD card via card reader.

LR reads and allows me to edit these OK

If I then edit the .X3F files using Sigma Photo Pro v5.1, and change WB to "Monochrome", then save the modification to the raw file (in SPP5.1), and then attempt to look at it in LR in the develop module (with or without deleting and reimporting the .x3f) , I get the error "There was a problem working with the file"..

Followed by "Lightroom has encountered problems reading this photo. You will not be able to make adjustments to the photo."

I have tried this a number of times with different X3F image files with the same result.

I have tried (separately) synchronizing, deleting and re-importing the file with the same result.

LR3 worked perfectly in this regard - if a .X3F file was imported, then changed using SPP5.1 to mono, the effect would be immediately seen in LR without errors.

NB If I then set the WB back from monochrome in SPP5.1, LR is able to work with theimage file again with noerrors.

I have also encountered similar error messages when trying to export jpgs from edited .tiff files created using a film scanner, which may be related. When or if I can reproduce consistently that I will start a separate thread.

OK but I can't attach images here >2MB here and the X3F is 17.1MB ... is there an address I can send it to? Or another place I can attach/upload?

That works. I'll have engineering grab it.

Hi Paul,

This file works just fine for me in Lightroom 4.0 and 4.1 on Mac and Win. It imports, and adjusts in Develop with no problems. Maybe you can send me an original file (that you have not yet modified in SPP) and I'll try it with your whole workflow?

I often shoot with a Sigma myself (the DP1), so I have already tried this with my own files, and I am not able to reproduce the problem that you describe. Could conceivably be a difference between your files and mine, however, particularly if you're shooting with something other than the DP1.

Incidentally, that's an interesting workflow. Out of curiosity, why not just convert the photo to black and white in Lightroom?

Thanks,
Ben

thanks Ben.
I'll sort out an original in due course and skydrive it again and post the link as b4
.
as for workflow ... well it's more of a workstumble with the Sigma ... I use LR as the image manager and always import from card into LR so it's in the right directory and can be keyworded and so on ... but I find that sometimes I get optimal results by working the file over in SPP5.1 (or even 4 or 3!) then importing it into LR as a TIFF (usually just by syncing the directory); the problem with that is having to manually stack the tiff, x3f and any vcs and jpgs.
Of course sometimes LR is fine on it's own.
(the joys of the Sigma owner)
So this isn't a standard workflow at all, but as the error was occurring consistently and was reproducible in 4.x but not 3.x, I thought it worth reporting.
I'm also hitting terrible terrible performance issues in 4.x like many others, but that will have to be addressed separately.
