Photography Tools

Calculate crop factor, 35mm equivalent focal length, angle of view, field of view, and equivalent aperture for full frame, APS-C, Micro Four Thirds, medium format, cinema, and custom sensor sizes.

Calculate depth of field, hyperfocal distance, near and far focus limits and circle of confusion for any camera and lens. Includes an interactive visualization and a real-time aperture comparison for photographers.

Balance ISO, aperture (f-stop), and shutter speed with equivalent exposure settings. Change one exposure triangle value and see the matching settings that preserve the same EV.

Calculate exact golden hour and blue hour times for any location and date. Get optimal photography lighting windows with stunning visual timeline, sun position animations, and detailed shooting recommendations for photographers.

Calculate the maximum print size from a camera megapixel count, aspect ratio, and DPI. See pixel dimensions, quality grades for standard print sizes (4x6 to 24x36), and viewing-distance recommendations.

Estimate the file size of a photo in JPEG, RAW, TIFF, HEIC, and PNG formats from megapixels, bit depth, and quality. See exactly how many photos fit on your SD card, SSD, or hard drive.
