Photography
Exposure Calculator
Find the equivalent shutter speed when you change aperture, keeping overall exposure constant. Essential when switching f-stops mid-shoot without altering brightness.

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.
Photography
Panorama Calculator
Calculate how many shots you need to cover a panorama, given your lens, sensor, and desired overlap. Use it when planning stitched panoramas to avoid gaps between frames.
