Re: Center Filter

dear felix- i hafta hear back from 
gene first. you are absolutely correct. do  you know the  hypergon
lens with the propellor out front to even up light distribution? well,
frits rotgans pointed his camera with such a lens at a brightly lighted
light colored wall, indoor or out. outdoor is easier. he developed several
negatives to random densities. actually he had picture of the falloff,
right. did i mention glass plate. excuse me. we now have matching filter
for that lens and it's front mounted. got that? thank you, frits rotgans!  
this is  complicated compared to fix gene needs.

I was just wondering about center weighted filters, could you possibly
expose some b&w film through the lens you need to correct and process it to
the right density?  I guess the size would be wrong but you might be able
to fix that some how by using other optics.  Anyone done this?
