Nice demo. It's funny. When I have used the features in PS or Lightroom to
correct for the keystone effect of pointing a camera upward, I play and play
and usually get the lines nice and straight as in your second example, but
after looking at it for quite some time, I usually go back to the original,
or at least to one that is less perfectly corrected, as the perfect one just
looks funny. Maybe it is because after 40+ years of photography, I have
just gotten use to the effect, and expect the effect when I view a photo
that I know was taken in this manner. So, I will go uncorrect the image and
maybe go half way to perfect lines and it looks better to my eye. Maybe my
eye needs adjustments. Maybe I should have been weaned on a view camera
with all the shifts and tilts so I would have grown up not expecting
keystone looking photos.
Do I need help?
But more on topic, does PTlens do things that PS and Lightroom cannot do?
