Lens and focus calculations

Calculate hyperfocal distance and depth of field in feet or meters. Find what angle of view has a lens on your sensor and what is the corresponding focal length on a full frame camera.

aperture

Diffraction aware

Digital Photo Calculator calculates diffraction for given aperture and sensor size. This allows optimizing the depth of field or hyperfocal distance settings to preserve maximum detail.

sensor

Resolution based DOF

Unlike traditional calculators and DOF tables, the hyperfocal distance and depth of field calculator uses sensor resolution to determine optimal criteria for acceptable sharpness. The resulting calculated depth of field ensures thato objecs within depth of field are as sharp as your camera sensor can resolve.

unit conversion

Support for meters and feet

Select meters or feet as base unit in DOF and hyperfocal distance calculations. The app will remember your settings so that you don't have to set it every time you use Digital Photo Calculator.

Color conversions

Convert color values between RGB color spaces and Lab, XYZ, xyY, LCh and LUV.

aperture

17 RGB color spaces

There are seventeen photography related color spaces to choose from. The selection includes sRGB, AdobeRGB, ProPhoto RGB in three variations and DCI-P3 now used in some Apple devices.

sensor

Non-RGB color support

Non-RGB color support includes Lab, XYZ, xyY, LCh and LUV. DPC also shows approximate color name, optical density and color temperature info.

unit conversion

Color gamut preview

Preview color gamut of RGB color spaces involved in the conversion. Find if the color fits in the target color gamut or compare gamut sizes. The gamut is displayed in 2D on top of CIE 1931 chromaticity diagram.

Sun and Moon

Sunrise, sunset, moonrise and moonset time and azimuth. Sun and Moon transit time. Dawn and dusk times. Sun and Moon elevation angle. Moon phase and illumination. Shadow length. Interactive display of Sun and Moon positions.

aperture

Any place, any time

Sun and Moon information can be obtained for future and past dates and times and for any place.Point the place on a map, search it by address or enter geographic coordinates.

sensor

Interactive preview

Every change in date, time, position or used lens is immediately processed and all relevant data a images are updated.

Extra details

Many details like dawn and dusk time, length of shadow, elevation, rise and set times are just a tap away in a separate view.

Sensor

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

aperture

52 sensor sizes

Select one from 52 sensor sizes, specify your sensor resolution in megapixels and the calculator will estimate width and height in pixels, pixel density, resolution in lp/mm, pixel pitch and suggests max. aperture that does not introduce blur due to diffraction.

sensor

Effect of filters

Specify if your camera has AA filter and Bayer filter to achieve more accurate estimate in resolution and max. recommended aperture.

sensor

Reused in other modules

Sensor information is used in DOF calculations, crop factor calculations and in the Sun and Moon module.
