Professional photography tools and calculators for perfect shots every time. Calculate depth of field, exposure settings, golden hour times, and much more.
Calculate the depth of field for your shot based on camera settings. Depth of field is the distance between the nearest and farthest objects that appear acceptably sharp in your photo.
Find the closest distance at which a lens can be focused while keeping objects at infinity acceptably sharp. When focused at the hyperfocal distance, everything from half that distance to infinity will be in focus.
Calculate equivalent exposures using the reciprocity law. Change one setting and see how to maintain the same exposure by adjusting the others.
Calculate f-stop relationships and understand how aperture affects exposure and depth of field.
Calculate optimal shutter speeds for different scenarios using the reciprocal rule for handheld photography.
Calculate ISO adjustments for exposure compensation and understand noise implications at different sensitivity levels.
Calculate flash power settings, guide numbers, and flash-to-subject distances for proper exposure.
Calculate the field of view (angle of view) based on sensor size and focal length. Useful for composition planning.
Calculate optimal print sizes based on image resolution and desired print quality (DPI).
Calculate and convert between different aspect ratios. Perfect for cropping and social media formatting.
Calculate crop factors for different sensor sizes and understand how they affect focal length equivalency.
Calculate equivalent focal lengths across different sensor formats.
Calculate sunrise and sunset times for any location and date.
Calculate golden hour times when the sun creates warm, soft lighting perfect for portraits and landscapes.
Calculate blue hour times during twilight when the sky has a deep blue color, perfect for cityscapes.
Calculate moon phases and illumination for planning night photography and astrophotography.
Calculate the total weight of your photography gear to plan for travel and hiking.
Estimate camera battery life based on shooting patterns, settings, and usage.
Calculate how many photos or videos you can store on your memory card.
