Photography
Depth of field, exposure, and print calculators for photographers.
- Aspect Ratio Crop CalculatorImage dimensions + target ratio (16:9, 4:5, 1:1…) → centered crop size and offsets.
- Depth of Field CalculatorFocal length, aperture, distance, and sensor size → near/far DOF limits.
- Exposure Triangle CalculatorChange aperture, shutter, or ISO by stops → equivalent exposure compensations.
- Flash Guide Number CalculatorGN = distance × f-number — solve aperture, distance, or guide number, with ISO scaling.
- Hyperfocal Distance CalculatorFocal length, aperture, and sensor size → hyperfocal distance and sharp range.
- ND Filter Shutter Speed CalculatorBase shutter + ND strength → long-exposure shutter speed, or find the ND you need.
- Print Resolution (DPI) CalculatorPixels + print size → DPI with quality flags, or reverse for required pixels.
- Timelapse Interval CalculatorClip length + frame rate + shooting time → shot interval, or the reverse.
