I'm focus pulling on a short film this week. We are shooting on the Alexa Mini with 2x Kowa Anamorphic lenses. I've worked with anamorphic on a fair few jobs in the past, however I haven't always had the luxury of a prep day. On this short film I have an evening of prep before principle photography begins. I was wondering if I could get some advice on the kind of things I should prep/look out for when shooting on vintage anamorphics?
I'll do the obvious and check the accuracy of focal distances to start with. As far as i'm aware each lens will cast a slightly different colour tint onto the image, how can I test this and compensate during shooting?
We are also going to be using diopters for a few close-up shots in the short film. Any advice on pulling with diopters in front of the lens? Is there an algorithm that can be used to figure out focal distances for different diopter levels? Or is it recommended that I just rely on a monitor for these shots?
