The secret feature of every good 120 TLR !
Hidden inside every 6x6 negative,
is a 35mm headshot made by a perfect portrait lens.
With a cheap old Durst enlarger from the '50s or '60s,
and a Rolleiflex/Minolta/Mamiya/WhatHaveYou,
you can do world class work.
All that has changed since the heyday of the TLR is that films are so, so, so much better today.
