When you're taking photographs, it's very important to understand how your shutter works. And, what exactly shutter speed means.
Basically, the shutter is a solid object that's going to close down in front of your camera sensors. Or, on an older film camera it's going to close down in front of your film. And, the little flap is going to move up for a certain amount of time. Which, you determine by choosing your shutter speed. And, that's going to determine how much light gets in.
You see here, I've got my camera set to a very slow shutter speed. So, you're going to notice that when I push the button the shutter moves and stays open. Because, I've got it set to like a two second shutter speed and then closes.
Basically, what's happening is that is moving up. It's allowing the light to come in. And, then it's closing when we say hey that's enough light.
Again, that was actually four seconds. Now, a typical photograph taken here we'll take it one two hundred fiftieth of a second. And, you'll notice this time it's going to move a lot faster.
So, when there's more light in the room you want a faster shutter speed. And, again we can crank it all the way up to eight thousand. And, you'll notice how fast this one eight thousandths of a second that the shutter is open. It is very, very fast.
Again, so the faster the shutter opens and closes the less light that comes in. So, if you're in a low light situation you want a slower shutter. When you're in a medium light situation, medium shutter. And, high light situations you want that shutter to be moving really fast. So, you don't get too much light in there.
So, it's important when taking photographs to understand exactly how the shutter speed works. Because, if you don't you're either going to let too much or too little light in on your film and/or your digital sensors.
