I was reading a post today where the poster asked if there was a “better way to ensure that an image is correctly exposed?”
Now if there is one question that can split an audience, it is this question.
It is like Marmite!
Firstly, this post is a direct result of reading this post on the Strobist blog. Secondly, after my experience with the last model I thought it time for a change, hence my new model Gurty d’ Giraffe. While I admit she may not be much to write home about, she does take direction well, where you put here she stays and she doesn’t expect small talk during the shoot. For a novice like me that’s a Godsend and leaves me to concentrate on the matter at hand which is taking pictures (lots of them and slowly). Anyway that’s enough about Gurty, on to the subject of Balancing Flash with Ambient Light.
An f-number (f/8 for example) is a unit that is used to describe the apparent size of a camera’s aperture (the hole that allows light to hit the sensor in the case of a DSLR). The difference between two sequential f-numbers is called a stop and each stop is effectively the halving or doubling of the intensity of light from one f-number to the next.
How come ghosts, ghouls, vampires, werewolves, zombies and other similar creatures use and understand the Inverse Square Law (ISL) when us humans fear it as much as we do them?
Don’t worry, I’m not going mad, but it’s true. If it wasn’t for the Inverse Square Law horror movies would not be what they are today.
