[19 / 8 / ?]
This is not my photograph but I need some advice about IR film photography.
I have an Olympus OM10 with the 50 mm 1.8 lens which I will be using with Rollei IR400 film and an R72 filter. The camera manual says I shouldn't have a problem using the OM10 with this lens for IR.
I assume that the electronic metering will be useless with the IR filter (is this true?) so I'll use the Sunny 16 rule to estimate my exposure.
I read that, with an R72 filter, I should treat 400 ISO film as though it is 25 ISO. So, on a sunny day, I would set aperture to f16 and shutter speed to 1/25 s in order to get the correct exposure.
Is this going to work?
