I finally mixed up a batch of 510-PYRO and here are some preliminary testing results. I first determined the EI of each film using the 0.10 over b+f method. I determined the following:
510-PYRO
1:100
70 Deg.
Rotary Development on Beseler Base
Efke 25 = 50 ASA
Kodak TMX = 100 ASA
Fuji Acros = 100 ASA
I then shot 10 individual frames using an evenly lit white board, constant aperture and shutter speed and stacking ND filters to rule out inconsistent shutters/apertures. I was amazed how TMX and Acros are almost identical. I was also surprised by the speed of the Efke 25 but that film built up density fast, so maybe a lower dilution? Do these results track with anyone else that has tested these?
