Timelapse Calculator
Calculate the shooting interval between frames for a timelapse sequence. Use it before a shoot to set your intervalometer correctly and hit a target video length.

Between 1/60s and 0.5s, handheld shake is likely below the 1/focal-length rule. Brace the camera or use stabilization to stay sharp.
Shutter speed scales with the square of the aperture ratio; this bands the resulting exposure time in seconds against camera-shake and tripod rules.
