I am researching Leica lenses since internet and computer speed reached to
a reasonable value.
I want to do 3 things.
Old leica lenses have lower sagittal and higher tangential mtf curve.
Can I play with these two curves independently on a photograph ?
Other thing is,
There use of rare earth metals in glasses.
Can I simulate multi band pass filters to see the effects ?
And the third thing comes from mona lisa. Can I increase the chaotic nature
of grade edges goes to darker grades , darker the grade more chaotic grade
borders ?
Thank you,
