Shooting Car Background Plates for Rear Projections (3 replies)

Hi,

I'm going to be shooting Car background plates at night for use in rear projection filming. Any advice to what sort of focal length and what to look out for to make it look as natural as possible? 

We'll be using the Blackmagic 6K to film, super35 sensor. I'm thinking of using around 16-24mm as my focal lengths to look out the side windows and probably a 35mm for the rear. Any thoughts to help?

You can always make a plate tighter (longer focal length) by cropping in — usually the plate ends up out of focus anyway, especially for a night scene, so increase in noise or loss of sharpness is hard to detect. So it’s better to err on shooting plates a bit wider-angle than the lens used for the scene, plus you are often not re-shooting the projected plate corner to corner anyway, it gets cropped a bit in view.

Thanks. I think that's what I figured, just needed some confirmation.

We're purchasing some white reflective fabric to stretch behind the car in a studio and seeing if we can light the subjects from the projection as well. 

Any recommendations for projector models to use if you've done this DIY style before?

I just watched this tutorial» the other day on the subject. I hope that it can help.
