Hey Shibu,
That’s interesting to see the different IR takes.
First off. I would clone out those 3 small bits of brush poking into the bottom of the shot. Clean edges really make a difference in a shot.
In #1, I wonder where the halo around the trees came from? I would have thought that this being your original is the cleanest.
#2, is m favorite. Nice work with the colorized version.
#3, this is pretty cool, I like this old tin type feel.
