Below are additional tips for creating raw Panoramas in Lightroom CC:
• If you have made adjustments to the individual images prior to choosing Photo > Photo Merge > Panorama, not all of them carry over to the merged file. For example, if you have made local adjustments – such as applying the radial or a graduated filter, or painting in selective areas with the adjustment brush on individual exposures, those adjustments will not be applied to the merged file! Because of this, I would suggest that you don’t spend a great deal of time making adjustments to each of the individual exposures but, instead, merge the images and then make adjustments to the resulting Panorama image.
• The settings that are NOT copied over from individual exposures to the merged panorama are:
– Lens Corrections/Upright (with the exception of Defringe settings), since the merge tool is changing geometric attributes, and does not copy over existing geometric settings.
– Local Corrections
– Red Eye
– Spot Healing
• If you make adjustments to an individual exposures that can be copied over to the merged file (such as conversion to B/W or Split Toning adjustments) , make sure that the exposure with the adjustments is the “most selected” image.
Command + Shift + M (Mac) | Control + Shift + m (Win) will run Photo Merge > Panorama based on the last used settings (without displaying the Merge preview window).
• By default Lightroom appends the file name with -Pano. Although you can not change the default file naming convention, you can always rename after the file is created.
Post-merge, lens profiles don’t make any sense to apply to panoramas, so the feature is disabled.
• There is a size limit of 65,000 pixels on the long side of a file or, 512 MP – whichever comes first.
