Anyone who's studied photography knows that the main factor is light. There are two variables: aperture (how big the opening gets) and shutter speed (how long the shutter stays open). Both basically fulfill an equation that looks something like this:
light coming in x time= exposure
Lost yet? Yeah, that's what I thought. So I made a little diagram...
So in other words, you need a certain amount of light and the two factors have to balance that out. But--since each has a different effect-- you might want to swap one for the other. This is known as reciprocity. Like so....
You see, if your shutter speed is too long, all the sudden you need MORE time to make sure enough light gets in. I'm sure someday this odd fact will start to make sense to me, but for now... it's proof to me that math is completely overestimated and unpredictable.
I have no clue what you just said! Haha! But kudos to you! :-)
ReplyDeleteI don't have a clue either. Math smarts waved bye-bye to me when they started putting letters with the numbers.
ReplyDeleteGood luck with the fun part of photog stuff!
Photography is SO confusing to me. I have two beautiful film cameras, but have basically no idea how to use 'em. All the shutter speed, light, and aperture talk goes way over my head.
