I'm looking for resources for understanding the topics in the title. I prefer video tutorials as opposed to books but I couldn't find any video resources on Photometry and Radiometry (I guess I'll have to settle for books). As for Optics, I plan on studying the series on Khan Academy/iLectureOnline (unless you guys suggest something else).

In general I'm looking for resources that would help me understand the physics behind Radiance(the command line program), concepts and terminologies such as Lighting, Daylighting, Artificial Lighting, Sky types, Illuminance, Luminance, Radiation, Brightness, Luminosity, Flux, etc. including their relationship to material properties (e.g. transmissivity, transmittance, reflectance, specularity, etc.)

I have a background in multivariable calculus so it might be easier for me to understand these topics in terms of Math. I do have an idea of these topics, but they're descriptive for the most part, not concrete/mathematical. But of course it'd be better if the resources are both descriptive and mathematical.

Let me know if I've missed some topics that would be crucial for understanding Radiance.

Pretty sure it was you who posted this same question to radiance-general. I would definitely reiterate Roland Schregle's excellent answer over there; get yourself a copy of Rendering with Radiance, and I absolutely agree that Physically Based Rendering is an amazing text on the math of all this stuff.

Any general physics text will give you the deets on the radiometric and photometric quantities, measurements and calculations.

The IES Lighting Handbook is a good text for answering all the lighting questions you posed here, and personally, I love Color Imaging for its ability to tie a lot of this stuff together.

The IES does an excellent "Fundamentals of Lighting" course, which covers the practical side of lighting design, and the textbook is available as a self-study guide. See:

Would you also recommend The Lighting Handbook by IES?

Yeah, see above. =)

It is designer's working reference; large and expensive. It's a very good book, but unless you're planning on working as a designer perhaps more than you need, though it's nice to be able to consult it from time to time.

Oh yeah. Thanks!

I've always considered Erco's Handbook of Lighting Design to be like a condensed version of the IES handbook - with obvious manufacturer's product spin on any explanatory illustrations.
