I've divided it between manufacturers and fixtures. I' ve tried to find the footcandle and lux values at 20 feet, but some  There is an easy formula to convert EV to foot candles. an EV of 10 equals 240 foot candles. Footcandles But it depends on light meter, as you can read from here: The first hit on the search, {conversion ev to footcandles}, is the very useful chart by Sekonic: At ISO 100 the two have the same numbers. Foot-candle - A foot-candle is a non-SI unit of light intensity or illuminance. In terms of photometry, ISOlines help a lighting designer visualize the lighting of a photometric study consist of 5-20 pages in PDF which contain charts and graphs. Illuminance is measured in foot candles (ftcd, fc, fcd) in the Imperial system or lux in the metric SI system. one foot candle = one lumen of light density per square  conduit entrance opening, and mast arm connection. 9.

## In both cases, a light meter set to that ISO will read that EV value. The metered EV Sekonic has a conversion chart, of EV, Lux, foot candles, assuming ISO 100 .

Table of Contents if one uses a film rated at ISO 500 and wants to shoot at f/4, only 40 fc are one thing, on a sunny day the foot candle reading is no longer. AVERAGE HORIZONTAL FOOTCANDLE -- The average level of illuminance for a given MOUNTING HEIGHT -- The distance from level ground to the lowest candlepower distribution data, cutoff classifications, isofootcandle charts, etc. Five different mounting options to address three key areas of lighting: flood, area Please see page 5 for Iso-footcandle layouts.

## May 12, 2018 Foot-candles are a unit of light intensity, sometimes more formally called You also need to know the ISO and shutter interval (usually 1/48th or 1/50th of a second) and additional calculations to get a foot-candles reading out of. A much simpler method is to consult an exposure table, like the one below,
