test roll #3 with an auto exposimeter 6×12 pinhole camera

test roll #3 with an auto exposimeter 6x12 pinhole cameraThis five shots were my third and last test of Rudolph Crane’s prototype of pinhole camera with auto exposimeter. They were made on May the 13th in Barcelona with a reading of f/22 and exposure time between 1/8th and 1/4th of a second.
I used Ilford FP4+ 125 ASA film developed with homebrewed 510-Pyro at 20 ºC 1+100 for 08:00 [00:10 Ѻ/01:00]
I recorded the following data for each take:
1 f/22 and exp time between 1/8th and 1/4th; exposure time 5 sec; EV=-2.0
2 f/22 and exp time between 1/8th and 1/4th; exposure time 10 sec; EV=-1.0
3 f/22 and exp time between 1/8th and 1/4th; exposure time 23 sec; EV=0.0
4 f/22 and exp time between 1/8th and 1/4th; exposure time 1 min; EV=+1.0
5 f/22 and exp time between 1/8th and 1/4th; exposure time 2 min 35 sec; EV=+2.0

 

I want to thank Rudolph for allowing me to use his prototype camera, it has been a unique oportunity!
