I'm shooting this Saturday an exterior scene at a park. Very simple stuff. Problem is, I took readings earlier today at about the time I want to shoot, and for the stock I have (250D) the reading is just off the charts (f/32). I figure I'd change the time later in the day, but just to prepare for an especially sunny day with ND filters (at least .3, and maybe .6).
However, I also want to shoot these scenes at 48fps, which will be beneficial to my exposure problem. I'm wondering how I should go about using both an ND filter and a faster FPS and ultimately achieve the correct exposure. Additionally, how will ND affect the quality of the image and the depth of field considering the framerate?
Let's say for example that at 24 FPS and no filter I get a reading of f/11. If I crank to 48FPS and add an ND .3, what should I set the exposure to?
What if I add an ND .6 at 48 FPS in the same example?
