Re: Science - Light Questions.
Talking about emitted candelas is quite misleading as it is a vector not a scalar unit. The energy amount emitted by a luminous surface is the Lumen, which expresses the Luminous Flux. You could obtain the Luminous Flux from a perfectly diffusing surface (Lambertian) by dividing its maximum Luminous Intensity, along the… -
Science - Light Questions.
This is sort of a generic science question, not app-specific. Science Nerds, prepare yourself... I'm trying to find a table of light sources by apparent brightness. I'm trying to use a standardized scale for Emissive/Glow/Self illumination Maps based on apparent brightness. So, say you're painting emissive maps for the… -
Re: Science - Light Questions.
Hi, light measurement can be a little confusing because Photometry, Radiometry and common language overlap to some extent. In example Brightness is a perceptual concept tied to the perceiver. The Photometric unit you're looking for is Luminance [cd/m^2], where cd are candela, measure of the Luminous Intensity and m^2 are… -
Re: Science - Light Questions.
Ark - sort of, not quite. I want the brightness, not the color temp. That's a good chart though. What I want would have similar things (Quartz Lights, Tungsten, Sun, etc), but with candella ratings, etc. Sync - I was thinking Candelas and Luminance sounded similar; glad to hear they're related. The problem I have is that…
