What is the aperture of a Brownie Hawkeye? I've seen f14, f16, and f22 listed by different users. I was thinking about loading Ilford Delta 100 and assuming f16 at 1/50 second in full sun. This would mean at El 50 in Ilford Infosol S a development time of 6 1/2 minutes. Any recommendaions for exposure and developin that you have had success with would be greatly appreciated.
