35mm and 120 different dev times.

from Steve Nicholls (gl1500@chariot.net.au)
Is it me or are the dev times and/or iso ratings for 35mm and 120 different. The density from 35mm is excellent whereas from 120 [both under studio flash] the density appear to need about half to three quarters of a stop more exposure.

Film used B&W. APX 25, APX100 and TMX100 Developers Rodinal, Ilfosol

It would appear to me that 100 asa 120 roll to get equivelant density needs about 64asa.

Cameras Olympus OM1 and Hasselblad.

Colour tranny both cameras identical.

Regards Steve Nicholls.
