Then that would explain why Ron Crabtree got good results using his OM-4
without film and putting a spot reading in memory and syncing an exposure
based on this value with his Pentax 6x7. The exposure value based on the
spot reading would be related to pre-programmed OTF values but not based on
an OTF reading per se. Thanks for clarifying this, Warren.
