How To: Calculate Exposure for 'Black Glass' Filter

You would like to capture long exposure photographs in daylight? Then you need to significantly reduce the amount of light reaching your camera sensor. 'Black Glass' (BG) is a popular term for Neutral Density (ND) filters reducing the light by 10 stops, which means by a factor of 1000! Such filters are very, very dark and once attached to the lens of your DSLR you can't really see through, and in most cases the camera will be unable to focus or measure for exposure settings.

How to determine the camera exposure settings? This is where the Photoxor C1 filter calculator comes to help.

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.
