I had considered BIF. Again, figure out the fastest their wings can flap, set shutter to that as your minimum. Build your other settings around a fixed minimum shutter. Done. I don’t shoot BIF but I would start at 1/2500 shutter and see what happens. Adjust as needed.

If you’re proposing a setting that changes aperture and/or ISO to accommodate shutter based on metered readings, in order to generate relatively consistent exposures in shifting lighting conditions, well… I’ve got news for you…



It's a strategy that guarantees the lowest image quality possible for all but the peak moments of movement of the subject. And yes, ISO/gain would float based on the camera's calculated shutter speed. These are all light-limited scenarios - in situations where you're not light-limited then shutter speed would not be constrained.

But you can extend the same strategy for “higher quality images” with a little effort - by which I assume you simply mean lower ISO.

Not sure what you mean. In light-limited scenarios the lower ISO is only available if you can use a slower shutter speed.

It’s OK. I’m sure you’ll eventually figure out the solution to your pretend scenario
