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?
