Alaeddin, +/- 22 degrees around the vertical is easy. This is used typically with image reversal for metal lift off profiles. It sounds like you are asking for +/- 89 degrees around the vertical. Best of luck.

Hi There, Is it possible to apply gray scale lithography on metal material like copper? I would appreciate if anyone tried that and would I get a thicknessĀ slopeĀ ending with some nanometers? Looking forward to get feedback.
