Arduino and the TSL230R: Photographic Conversions

Projects | Time-lapse Video 26 26 Comments

In the previous post on using the Taos TSL230R with the Arduino, I covered the basic operations of the chip, and some essential conversions for going from radiometric to photometric representation of its data. In this post, we’ll expand on that knowledge to calculate exposure times and apertures using the Exposure Value system and produce much more accurate lux calculations using multiple wavelengths of light. After reading both of these tutorials, you should have enough information to create your own photographic light meter using a few simple components.
