Digital Photo Calculator

The Digital Photo Calculator is a tool for digital photographers, who need information about sensor resolution and diffraction limit, convert between RGB and Lab color spaces, calculate Dmax and Dmin values from their Lab measurements or want to calculate DOF and hyperfocal distance optimized for given sensor size and resolution.

Calculate pixel dimensions, pixel size, resolution and diffraction limit.

Convert values from Lab to RGB, RGB to Lab or between AdobeRGB, sRGB and ProPhoto RGB color spaces. Calculate color temperature or density from Lab values. Get preview of the color on your iPhone.

Calculate hyperfocal distance and depth of field. Use your sensor size and resolution as criteria for acceptable blur or use traditional, more forgiving standard. Find what angle of view has a lens on your sensor and what is the corresponding focal length on a full frame camera.

Sensor Properties

• Select MP and type of sensor (APS-H, APS C, FF etc.) and get dimensions of sensor in pixels and mm
• Get pixel density information, pixel size, estimated sensor resolution in lp/mm and diffraction limit (diffraction f-stop)
• Supported sensors: 1/6", 1/4", 1/3.6", 1/3.2", 1/2.7", 1/2.3", 1/2", 1/1.8", 1/1.7", 1/1.6", 2/3", 4/3", Nikon CX, Epic-M, Scarlet-X, APS C, APS Nikon, APS-H, FF (24x36mm), Leica S2, Pentax 645D, P 25+, 48x36 mm, 44x33 mm, P 45+, H3DII-31, H4D-31, P 30+, H3DII-39, H4D-40, AFi-II 10, Aptus-II 10, H4D-50, H4D-200MS, P 65+, IQ160, P 40+, IQ140, H4D-60, H3DII-50, Aptus-II 8, AFi-II 12, Aptus-II 12, IQ180

Color Conversions

• Convert color values between color spaces
• Lab to RGB
• RGB to Lab
• RGB to RGB
• Supported RGB spaces are sRGB, AdobeRGB and ProPhotoRGB
• Result is displayed as a set of numeric values and a color patch

Print Density

• Calculate density from Lab or RGB.
• Calculate Dmax or Dmin from Lab or RGB: Read darkest or lightest areas of your print with X-Rite ColorMunki and get Dmax and Dmin from ColorMunki's Lab reading.

Hyperfocal distance, closest sharp distance and optimal f-stop

Unlike many other calculators the hyperfocal distance is calculated from sensor data and diffraction limit and ensures that the closest distance and infinity are as sharp as the sensor can resolve and for the largest f-stop number that will not be diffraction limited. Traditional "Zeiss formula" calculation also available.

Calculate depth of field and near and far edges tailored to your sensor

Unlike many other calculators the DOF is calculated from sensor data. The calculated depth of field is shallower than that calculated by some other calculators and ensures that the edges are as sharp as your camera sensor can resolve. Traditional "Zeiss formula" calculation also available.

Crop Factor Calculations

• Select MP and type of your sensor (APS-H, APS C, FF etc.) and get dimensions of your sensor in pixels and mm.
• Get pixel density information, pixel size, estimated sensor resolution in lp/mm and diffraction limit (diffraction f-stop)
