Inverse Square Law, Sunny 16 On Earth, Sunny 8 On Mars???
1

Yes the crude math in my head tells me that if I shoot sunny 16 on Earth then it must be about sunny 8 on Mars! LoL

Lets talk about the Inverse Square Law(ISL). I think most photographers don't know what the ISL is and why it's important or how it can benefit them.

Remember the photo threat a month ago about lighting the shoe? Some thought it could be shot with one light. Most Studio shooters know that the light falls off. If the light is correct on the subject then it's impossible to be correct at the background because of the ISL.

Here's a chance for all of you light engineers to shine a light on this subject!

What is the ISL and how can we use it to benefit from this knowledge in our every day photography?

But here's a hint, if it's Sunny 16 anywhere on Earth, will it be Sunny 8 on Mars?
