Title: AutoPano Pro problem
Post by: Jeremy Roussak on April 21, 2009, 02:43:58 pm

I'm having a problem with AutoPano Pro. My workflow is:

1. Import raw files (from 5d2) into Lightroom and fiddle appropriately
2. Export as 16-bit TIFFs in ProPhotoRGB space
3. Import into APP and stitch into 16-bit TIFF
4. Import the resulting panorama into Lightroom

The stitch is fine, but all the colours are way off. After some discussion with the helpful author of APP, I discovered that if I import the panorama into Photoshop and manually assign it the ProPhotoRGB profile (Edit->Assign Profile), the colours return to normal.

Alexandre doesn't seem to think he'll be able to fix this for the release of the new version of APP, which is a shame.

Has this problem really not bitten anyone else? Is there an easier way round it than assigning the profile using PS? I'm using the beta rc2 version of APP.

Any suggestions gratefully received. Bernard?

I do agree it's pretty lame that he can't just preserve the embedded profile from the original images. The only workaround is to assign the correct profile, which isn't too big a deal but kind of annoying. You can batch it in Photoshop/Bridge but I don't know about Lightroom.

Try PTGui. Anyway, it's not a big deal to assign a color profile.

Well, I know I'm going to open the pano in Photoshop at some stage, and then the dialogue for assigning a profile comes up before the image appears. So I don't worry that the colours look off in LR in the meantime. But I guess if you are doing stuff like comparing colours in LR beforehand then it would be annoying.

Yes... this is a known limitation and one of the highest priority requests to Autopano pro R&D team.

The by-pass you have found is the one I have been using also. Autopano pro doesn't really do much on colors (no change of RGB values), so the image should look mostly the same in a color managed application if the profile associated to the resulting pano is the same one the initial raws were converted to.

Cheers,
Bernard

I hadn't noticed that though all of my stuff ends up in B&W anyway and the RAWs are processed for max DR before being sent to APP.
