Capturing near, farfield lens aberrations with multi stacked thick emulsion layers
Ship hydrodynamics research near and far field wakes seperately as lens designers classifies the success of a lens design before focus , focus and after focus aberrations graphs.
I learned that thickness of an emulsion is an active element and turns effectiveness of grains in 3D.
I thought what happens if we use a 1 centimeters thick emulsion and focus the lens in the half distance.
There would be continious recording of all calculated aberrations in this thickness. But reading this thick record needed may be a digital tool and for each time I opened my mouth to digital , susan deletes my ideas , I decided to put 3 separeted emulsions.
By this way , if we want to use one of the aberrated layer to create a impressionist picture , it would be a wise decision. We can mask each other and print different areas with different taste.
