Is there such a filter that allows you to focus only on small part of the frame, (not necessarily in the middle, using a very wide lens (and working with f/stop around 2.8)?
any experience with any of these filters?
the scene is the following: frontal shot of the nurse holding a big siring, I want to focus on the big distorted needle in the very foreground, blurring the rest of the image, and being able to rack focus to the character. Can I do it with a filter on set and not in post?
thank you so much
