Lightroom 6: Clone brush ineffective on Panorama's white edges.

Loving the new LR6 Panorama feature! Just noticing a bug using the Spot Edit brush on merged panoramas. I can't seem to paint on the white "edge" space with the brush. The white edge remains white, even if the brush is set to clone mode.

This is not a bug. Lightroom is not Photoshop. There is no concept of enlarging a canvas and replacing those extra pixels with new content.

You can only replace image pixels with the clone brush. The white edges around a panorama are where there are no image pixels. The same thing will happen with the white area around an image with lens-corrections applied.

Here I have shrunk, rotated, pinched a normal-sized image so there is white all the way around, and the clone brush won't replace any of those white pixels. In addition you can see how the source and destination areas of different sizes indicating the brush is operating on the pre-warped pixels and the destination is not replaced beyond the edges of the photo:

If it's not a bug, I'd say it's a feature request then. It's strange to me that it would behave this way by design. I used to go through Photoshop to stitch my panoramas, and I could paint freely in the resulting image's white space if there was a "gap" I wanted to close. Perhaps some kind of checkbox to alternate between allowing white space manipulation or not would be nice?

To clarify, I meant back in Lightroom I could paint anywhere in the resulting panoramic image made in Photoshop. There never used to be white space restrictions, which is why it stood out to me in this new version.

That is because Photoshop created new pixels outside the original panorama pixels that LR is happy to replace the content of. What LR doesn't do is make up new pixels outside the extent of the image pixels.

What you could be asking for is that the DNG result of a panorama not be masked to the now warped edges of the original images. That is where the issue is, not LR.

What you could do is export the panorama to a TIF and then reimport and clone the white pixels of that TIF.

Hi James,

I understand what you're trying to do here, but as Steve noted, this is currently a design limitation of the current spot tool and how it deals with transparent pixels (in this case, the undefined areas of a stitched panorama). We'll be investigating how to improve this in the future, but for now the best solution is to "fill in" the edges using Photoshop, or to "round trip" the image through Lightroom.

Cheers,
Eric

Thanks everyone for your help. I guess I understand what Lightroom is going for here. Might be fun some day to have some sort of "paint over transparent pixels" option. But I can also see that being too confusing for most users. I'm happy to round-trip to Photoshop for this rare situation. Thanks, again, for your thoughts.

Now I'm still a bit disappointed LR6 didn't implement another feature I've been pining for; anamorphic lens support: http://gsfn.us/t/49f78

For ideas on how to handle the problem, take a look at what the updated Microsoft ICE does. They have an autocomplete feature on the Crop page that does a content aware fill for the white areas. For the most part it works pretty well. All in all, its quite handy to have the pano feature, such as it is, embedded in LR. Thanks for moving forward with enhancements.

This reply was created from a merged topic originally titled Lightroom: cannot clone/heal corners of a merged panorama in LR CC.

When photo merging a panorama, I cannot clone/heal the white corners. Sometimes I do not want to crop out white corners of a panorama, if I can easily clone in say a blue sky. It allows me to retain more of the image. But clone/heal does not seem to work on these corners.

LR should fix this problem

Hi LR Team,
I have often used one of the possible workarounds just to fix a very small white area. Please fix this feature and allow LR to paint over transparent areas. In real live it is not possible to paint on nothing but in LR it should not be a big deal.
Thank you.
