I am researching 3D Popup Relief Images of Leica and I found that effect is a treasure for microscopy.

I found that decentered apertures are used to get that effect.

And I found another thing , if enlarger light have a decentered aperture and if that light passes the negative , this has a effect, if you want more if that decentered light, passes the negative and hit another film which has 3 gradients where they are %1 , % 15 and % 100 , it has more effect.

Anyone who has a enlarger , can do this.
