Photography & Media Calculators
Whether you are a professional photographer, videographer, or hobbyist, having the right technical data makes all the difference. Our 12 photography and media calculators cover everything from depth of field and exposure settings to video file sizes and print resolution. Calculate the perfect shutter speed for motion blur, find equivalent focal lengths across sensor formats, or estimate golden hour timing for your next shoot. These tools help you plan, shoot, and deliver with confidence.

Frequently Asked Questions
How do I calculate depth of field for my lens?
Depth of field depends on three factors: aperture (f-stop), focal length, and distance to subject. A wider aperture (lower f-number) produces shallower DOF, while a narrower aperture gives more of the scene in focus. Our DOF calculator lets you enter your camera sensor size, focal length, aperture, and subject distance to see the exact near and far focus limits.
What is the exposure triangle and how do these calculators help?
The exposure triangle consists of aperture, shutter speed, and ISO. Changing one requires adjusting another to maintain correct exposure. Our exposure calculator and shutter speed calculator help you find equivalent exposures when you change one setting, so you can maintain proper brightness while achieving your desired creative effect.
How do I calculate video file size before recording?
Video file size depends on resolution, frame rate, bit depth, and codec compression. Our video file size calculator lets you input these parameters to estimate the storage needed for your recording. This helps you plan storage capacity for shoots, especially when working with high-resolution formats like 4K or 8K.
What is the golden hour and why does it matter for photography?
The golden hour is the period shortly after sunrise or before sunset when sunlight is warm, soft, and diffused. It produces flattering light for portraits and dramatic landscapes. Our golden hour calculator estimates these times based on your location and date, helping you plan outdoor shoots for the best natural lighting conditions.
