After looking everywhere for it, I finally found an exposure chart for diana lomo f+. The chart has exposure times for all aperture sizes for any conditions, from "Night, Star Light, No Other Light", to "10 Minutes After Sunset", and for ISO speeds from 50 to 800.

The full chart can be downloaded for free in pdf mode from INDIAN HILL imageworks.

AA and A are the same...
ReplyDeleteThaaaaaaaaaaaaaaanks!! I was trying to find one too!! I've linked this post from my blog.
ReplyDeleteI don't get this. Is this for the "B" Long Exposure? Or just the "N" short one?
ReplyDeleteStuart - the highlighted 1/60 times are the "N" setting. The times higher than 1/2 are "B" (bulb) settings.
ReplyDeleteThere's really no way to shoot at 1/30s, 1/15s, or 1/8s on a Diana since it's a basic leaf shutter. Consider those three shutter speeds a dead-zone on the exposure chart -- Gray them out on your printed version.
You might be able to squeeze 1/4 second in bulb mode if you're quick enough. You basically have to press and release it exactly within a quarter-second to get that exposure. 1/2 second and up is totally doable however.. Just make sure to use the Diana shutter release kit
Correction - You can achieve 1/30s on a tripod by hitting the shutter button twice in "N" mode. Or take the opportunity to double-expose two shots. Either way, two shots at 1/60s adds up to 1/30s.
ReplyDeleteHere I was baffled by the 1/30 while was wondering why I was getting stressed about my photos messing up lately (I recently, stupidly, had two films that were badly exposed, and it annoyed me). The explanation of the 1/30 above fixes all. I am sure I'll just go back and forget all this and shoot away as before. Thanks for the clarification Neil.
ReplyDeleteI am sorry to ask that question, but, I can't figure out how to read this chart... For example, if I want to shoot with an ISO 100 film, in pinhole (f/150) the sky at night, what is the exposure time I need ?
ReplyDeleteBased on the chart, it would take longer than 12hrs to do, which would not allow long enough time in the dark to expose. You'd have to find some ISO 3200 film to get close. Even then, it might be too grainy to get you a useable image.
