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, conversions, and understand how aperture affects exposure and depth of field.
Calculate sunrise and sunset times for any location and date. Essential for planning outdoor photography sessions.
Calculate how many photos or videos you can store on your memory card based on file sizes and card capacity.
Calculate optimal shutter speeds for different scenarios and understand 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 and lens selection.
Calculate optimal print sizes based on image resolution and desired print quality (DPI). Determine maximum print dimensions for sharp results.
Calculate and convert between different aspect ratios. Perfect for cropping, print planning, and social media formatting.
Calculate crop factors for different sensor sizes and understand how they affect focal length equivalency and field of view.
Calculate equivalent focal lengths across different sensor formats. Perfect for lens comparison and system planning.
Calculate golden hour times when the sun is low on the horizon, creating 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 and architectural photography.
Calculate moon phases, rise/set times, and illumination percentage for planning night photography and astrophotography sessions.
Calculate the total weight of your photography gear to plan for travel, hiking, and determine tripod requirements.
Estimate camera battery life based on shooting patterns, settings, and usage to plan for long shoots and travel.
