Hello all,   
      
   Thank you very much for your all kind messages.   
      
   Let me try to tell what I am after. I am interested on relief effect of   
   portraits made by some Leica lenses which all face and hand muscles and bones   
   been recorded more than eye can see. I have a 111mm f:1.5 Kodak Fluro Ektar   
   lens and it does have the    
   same effect.   
      
   I am an archaeologist not a optics educated person and wasted lots of years on   
   net to understand what causes that effect.   
      
   Than I found Hoffman effect which makes a phase visible. I thought I can test   
   a Leica from its design , glass details and each lens elements for each phase   
   with zernike.   
      
   Than I found an ELCAN paper on Summicron 50 with Code V test for each element.   
      
   Now I am after to simulate these CODE V aberrations on a image for each lens   
   element and see how lens processes the image and what causes what.   
      
   I have no optics software and will complete everything on open source math   
   software.   
      
   I cant access CODE V manuals and few reported there is no equivalents of   
   definitions AFAIK.   
      
   So I need your help to break the cipher.   
      
   Thank you very much,
