Re: Infrared Pinhole Exposure Times?

My wife shoots alot of infrared on standard camera at 120 ISO, but the
results vary according to a whole lot of factors. So if you read your
light and work out your exposure depending on your pinhole camera's
f-stop, this should give you a time exposure.

She has not tried pinholing on infrared but has tried zoneplate, but she
did not get the kind of results she expected and did not pursue it.

Hope this helps,
