Translate shutter angle into exposure time for camera crews.
Exposure duration: 20.8333333 ms Reciprocal exposure time: 48 s⁻¹ Exposure change from reference: 0 EV
t = θ/(360f); ΔEV = log₂(θ/θref)
Exposure duration: 20.8333333 ms Reciprocal exposure time: 48 s⁻¹ Exposure change from reference: 0 EV
No. It assumes uniform exposure and unchanged lighting, aperture and sensitivity; camera limits, rolling shutter and lighting flicker need separate checks.
