test roll #1 with an auto exposimeter 6×12 pinhole camera

#1765 test roll #1 with an auto exposimeter 6x12 pinhole cameraThis five shots were my first test of Rudolph Crane’s prototype of pinhole camera with auto exposimeter. They were made on april 18th in Barcelona with a reading of f/22 and exposure time between 1/8 and 1/4th of a second.

I used Efke 25 ASA film developed with homebrewed 510-Pyro at 20 ºC 1+100 for 07:00 [00:10 Ѻ/01:00]
I recorded the following data for each take:
1 f/22 between 1/8 y 1/4th; exposure time n.d.; EV=+0
2 f/22 between 1/8 y 1/4th; exposure time 42 sec; EV=-1
3 f/22 between 1/8 y 1/4th; exposure time 18 sec; EV=-2
4 f/22 between 1/8 y 1/4th; exposure time 12 sec; EV=-2,5
5 f/22 between 1/8 y 1/4th; exposure time 8 sec; EV=-3
