Re: [Lensfun-users] Lensfun 0.3.2-4: Profile for Ricoh GR III

2019-11-28 Thread Adam Keck 
Hi Al,

  I may not be correct in this understanding, but I think exiftool is
separate from lensfun. The GR III has a fixed lens so lensfun-based
software (e.g., Darktable) will probably get the lens right once the camera
is detected if your lensfun XML is correct. However exiftool is looking at
the metadata in the GR III image itself - which is either zeroed in GR III
images, or in a format unrecognized by exiftool. There's another metadata
tool called exiv2. Try that as well to see if it recognizes GR III lens
metadata.

Re: [Lensfun-users] Error when attempting TCA correction - Hugin Tools Missing

2018-06-22 Thread Adam Keck 
Hi Robert,

  Is the script calling the correct Python? There may be a homebrew Python
and a system Python - only one of which knows about hugin-tools.
