I would cheerfully use GIMP if I could be shown a process as simple and
as effective as PTLens seems to be. A number of ways have been described
all of which are, to my of thinking, complicated and time consuming.
Although my involvement with photography is purely as a hobby I tend not
to use a process if it requires a great deal of patience, skill and
specialised knowledge.
