Depth of field, exposure and print size. 22 free tools, no sign-up.

Depth of Field CalculatorCalculate the depth of field for any lens from focal length, aperture, subject distance, and sensor size. See near, far, and total sharp zone.Hyperfocal Distance CalculatorFind the hyperfocal distance for any lens and aperture. Focus there to keep everything from half that distance to infinity acceptably sharp.Crop Factor CalculatorConvert a lens focal length to its full frame equivalent using your camera crop factor. Compare APS-C, Micro Four Thirds, and more.Equivalent Aperture CalculatorConvert an aperture to its full frame equivalent for depth of field and light gathering across sensor sizes. Compare lenses fairly.Field of View CalculatorCalculate the angle of view of any lens from focal length and sensor size. See horizontal, vertical, and diagonal field of view in degrees.Exposure Value (EV) CalculatorCalculate the exposure value from aperture, shutter speed, and ISO. Convert between EV, light value, and camera settings for any scene.Sunny 16 Rule CalculatorApply the Sunny 16 rule to find shutter speed and aperture for any lighting from your ISO. Meter-free daylight exposure made simple.Flash Guide Number CalculatorCalculate flash aperture, distance, or guide number for correct exposure. Solve any of the three from the other two in meters or feet.Print Size and DPI CalculatorFind the largest quality print size from your image pixels and target DPI, or the DPI you get at a chosen print size. Inches and cm.Megapixel to Print Size CalculatorSee the largest print size your camera megapixels support at 150, 200, and 300 DPI. Turn a megapixel count into real print dimensions.Star Photography 500 Rule CalculatorFind the longest shutter speed before stars blur using the 500 and NPF rules from focal length and sensor. Sharp astrophotography.Time Lapse CalculatorPlan a time lapse: find clip length, frame count, interval, or shooting time from the others. Includes storage size and card estimate.ND Filter CalculatorCalculate the new shutter speed after adding a neutral density filter. Enter base shutter and ND stops to get long exposure times.Bellows Extension Factor CalculatorCalculate the exposure compensation in stops for macro and bellows extension from focal length and total lens extension. Fix dark macro shots.Reciprocal Shutter Rule CalculatorFind the slowest handheld shutter speed that avoids blur using the reciprocal rule from focal length, sensor, and image stabilization.Photo File Size EstimatorEstimate RAW and uncompressed image file size from megapixels and bit depth, plus JPEG sizes and how many fit on a memory card.Stops of Light CalculatorConvert changes in aperture, shutter speed, or ISO into stops of light and back. Understand equivalent exposures and stop differences.ISO Invariance and Noise ReferenceUnderstand ISO invariance, when to raise ISO versus brighten in post, and how ISO, noise, and dynamic range interact on modern sensors.Golden Hour and Blue Hour GuideLearn when golden hour and blue hour happen relative to sunrise and sunset, with a planner that estimates the windows from your sun times.Diffraction Limit CalculatorFind the aperture where diffraction starts to soften your images based on sensor and pixel size. Know the sharpest f-stop to use.Motion Blur Shutter Speed CalculatorFind the shutter speed to freeze or intentionally blur a moving subject from its speed, distance, and direction across the frame.Color Temperature and White Balance ReferenceLook up the color temperature in Kelvin for common light sources and match the right white balance preset for accurate photo colors.
