I've got 13 raw files of about 23MB each which make up a 180 degree panorama.
I tried to merge them in Lightroom cc and the file it produced was tiny. It was only 610kB in size and pixelates as soon as I try to enlarge it.
From what I've read I think I've probably exceeded the maximum file size? If that's the case then I'm still a relative beginner and I have no idea how to adjust it. Can you help?
Does the info in extended info in Grid view show this resolution?
If you got this low res after exporting the pano, show us the settings of the Export dialog.
