This conversation has been merged. Please reference the main conversation: Lightroom CC / 6 Photo Merge Settings not transferring in HDR and Panorama Merges

I have some photos in which I have used the spot removal brush. When I use these photos in a pano (Brenizer method) the spot removal is ignored and the items I cloned out are visible in the pano preview.

This is as designed. Do the merge first and then touch up the merged result. That is the recommended workflow.

Using the spot healed result for the merge could potentially adversely affects the merge process and results, thus the above recommended workflow.

That's fair enough.

However I found another issue. In this particular case Spherical and Cylindrical projections show different previews. I select the Cylindrical because it gives me the preview I want, but when I complete the merge the results are what the Spherical projection preview showed.

Example:

Spherical preview:


Cylindrical preview (the one I want):


Cylindrical merge result (matches spherical preview):

Are you talking about how the deer is posed, head-up vs head-down, that is not Cylindrical vs Spherical that is just luck-of-the-draw as far as which parts of which frames ACR decides to use when stitching, either in the preview and in the final results, which you can see are sometimes different.

To have some control over what happens when there an object is in a different location or orientation from one overlapping frame to the next, you can either use Photoshop CC which creates a masked layered document that allows adjusting the masks or you can use a different product that allows you to choose which parts of which frame in the stack has priority, for example, AutoPanoGiga:

http://www.kolor.com/autopano/autopan...

"Simple and efficient Mask tool: just place green targets on what to keep or red targets on what to discard

"Take control over the automatic anti-ghost tool of Autopano Giga: the brand new Mask tool lets you choose, in the overlapping areas, what you want to keep or discard in your panorama. No need to paint over the entire person or object: just place one or two targets on it and Autopano Giga will recognize the whole shape. And with the Preview mode described above, get an instant result of what your panorama will look like after the rendering depending on the different constraints you added."

Perhaps LR/ACR will have this capability someday, as we're only at the very first version of this new tool, or maybe, since PS can do it, using manual mask editing, that will always be the preferred way.

Your "luck of the draw" comment makes sense but that doesn't explain why the preview does not match the final result. I would consider that a bug.

The preview is just that, a preview, something computed quickly to give you an idea about how things will look. Normally there aren't moving objects in overlapping areas.

The merged result takes longer and is at a different scale, so different decisions about what to show and hide to avoid discontinuities are likely made a that larger scale so the results are different in the preview compared to the final result.

If your overlapping photos have moving objects in different locations from one frame to the next, then you'll need a more sophisticated tool.
