I am looking for some advice on how aperture is involved in miniature cinematography. I am planning on shooting two shots which appear from the same view point, a telescope, one which is live action and one which is a miniature. In order to make these both look the same scale I will be adjusting the camera set up by the scale of the model. I will be using 1:15 scale, so shooting the live action with a 300mm focal length and the miniature at 20mm. I've read that aperture should be adjusted the same way if wanting to make it seem that live action and miniature are the same size, so if shooting live action at f2, then i'd shoot the miniature at f30 (which poses problem with equipment). However, I still don't understand how this approach will replicate the same look. Surely, shooting live action at f2 will result in a shallow depth of field but shooting the miniature at f30, will have such a deep focus. If anyone can help me wrap my head around it then that would be great, thanks!
