[Leica] IMG: Threatening Weather

[Jim Nichols]

Ted,

Here are a pair of images that show the need for distortion correction 
and the corrected image.  Please ignore the shapely girl and look at the 
sidewalk. :-)

Image converted from RAW with no distortion correction applied:

The same image once the PTLens distortion correction was applied:

Incidentally, PTLens did not have data on this Fujinon 35/2.0 lens when 
I purchased the lens.  I shot sample photos and sent them to them, and 
they added the correction to their stock list of corrections.
