Photoxor C1 Introduction

Photoxor C1 is a photography tool for exposure and depth of field calculations.

Use the device camera based lightmeter to estimate an Exposure Value (EV) reading, determine camera settings and calculate adjustments needed for a (neutral density) filter.

The Depth of Field calculation shows the near and far limits of sharpness, and additionally provides a graphical visualisation of the level of sharpness and diffraction. The Circle of Confusion (CoC) is automatically calculated from the camera sensor size, but may be overridden with a custom value.

The Depth of Field calculation also allows specifying the range of sharpness (near and far limits) and calculates the needed camera settings.

The key features are:

• Aperture, time, ISOExposure calculations and Exposure Value (EV)
• Lightmeter (using device camera)
• ND filters and “Black Glass”
  Calculation on how a ND filter light reductions affects exposure settings
• Depth of Field calculations with graphical presentation of distance dependent sharpness level (CoC)
• Depth of Field reverse calculationCamera settings are determined based on required near and far sharpness limits
• Field of View calculationBoth dimensional and angularalso dimensional reverse calculation
• Define own cameras and custom Circle of Confusion (CoC)
• Define own filter characteristics (light reduction)
• Set your stop system (full, ½, 1/3, ¼ stops)
• Customize light wavelength for diffraction calculation (Airy Disk)
