Early January this year I was attracted by a special offer at DxO for their ViewPoint software, instead of the regular $79.00 US; I only have to pay $49.00 (NZ 60.00) ! It is a no brainer! I bought a copy!
What is this DxO ViewPoint?
In short, these are what it can do...
Fix key-stoning. Recreate the original shapes of buildings. Converging vertical and horizontal lines once again become parallel.
Restore the natural proportions of the people on the edges of your ultra wide photos in just one click.
