Exposure Summary
This keeps exposure roughly constant while you change depth of field and sensor gain. The shutter result is snapped to the nearest common stop for usability.
Starting from f/4, 1/250s, ISO 200, switching to f/2.8 and ISO 400 points you to about 0.0039 seconds, which maps to the common shutter stop 1/250s.
Stop Logic
The target settings shift exposure by 2.03 stops before shutter compensation. Positive values mean the new aperture and ISO combination gathers more light, so you need a faster shutter to keep exposure flat.
