Photography Calculators
Free photography calculators for depth of field, exposure triangle, print size DPI, video file size, aspect ratio cropping, golden hour times, time-lapse intervals, and photo storage. Essential tools for photographers and videographers.
Depth of Field Calculator
Calculate depth of field, near/far focus limits, and hyperfocal distance from focal length, aperture, subject distance, and sensor size.
Exposure Triangle Calculator
Calculate equivalent exposures by changing ISO, aperture, or shutter speed while maintaining the same exposure value.
Print Size & DPI Calculator
Calculate print dimensions from pixel dimensions and DPI, or find the required pixels for a target print size.
Video File Size Calculator
Estimate video file size from bitrate, duration, frame rate, codec, and audio bitrate for any resolution.
Aspect Ratio Crop Calculator
Calculate crop dimensions to fit a target aspect ratio from your original image dimensions with pixel-level precision.
Sunset & Golden Hour Calculator
Calculate golden hour, blue hour, sunrise, and sunset times from latitude, longitude, and date for perfect natural lighting.
Time-Lapse Interval Calculator
Calculate shooting interval, total shots, and final video duration for time-lapse photography with storage estimates.
Photo Storage Calculator
Estimate storage needs from number of photos, file format (RAW, JPEG, TIFF, HEIF), and camera megapixels.
