Your e.jpg and e3.jpg are different. Look at the edges. You can get a bigger difference by tweaking the "-modulate" numbers.

And what was the input file for my first command, the one that goes:

Code: Select all

%IM%convert effect.jpg ^
  -channel R -level -73.91%%,81.91%% ^
  -channel G -level -4%%,96%% ^
  -channel B -level -78.58%%,213.08%% ^
  +channel ^
  e.jpg
