FAQ
What lighting calculations can LuxCalc perform?
LuxCalc can calculate interrelations between luminance, aperture opening, sensitivity, and exposure time on its Exposure page. It also handles interrelations between luminance, light intensity, and distance on its Photometry page, and calculates key-to-fill light ratios on its Contrast page.
Can I customize how LuxCalc displays exposure time?
Yes, LuxCalc allows you to choose how exposure time is expressed. You can select between a combination of frames per second and shutter opening for video style, or as fractions of a second for photo style.
