Why are exposure times so long if light travels so fast?

[bribrius]

well the sensor doesn't want to just jump all over the light ya know. it wants to take time, get to know the light, get acquainted before it lets the light in to be absorbed. And it likes to go slow in increments. .

So what you are saying is that all images have a little Barry White embedded in the coding.....

Or maybe some Marvin Gaye. Push your camera's little button and it starts singing "Let's....get it on."

not all the time. just sometimes. slow. other times you put it on continuous and they like it hard and fast...
