Today's cameras put an amazing amount of power in the hands of amateur photographers, but it's not always easy to make use of it. All those buttons, dials, and settings can be pretty intimidating. In this workshop, expert photographer Joseph Linaschke helps you understand what's going on inside your camera, explaining fundamentals like what an aperture is and how shutter speed works. Learn basics such as how to hold the camera, what various modes mean and when to use them, and even how and when to use the camera's flash. There's also creative instruction to guide you towards becoming a better photographer. As you become more comfortable with your gear, you'll find that many new creative possibilities open up for you and the quality of your photography improves.
Depth of field is defined as how much is in focus, the depth of what's in focus from the singular plane of focus. So, for example, let's say you're shooting this direction and you're focused right here. You have a shallow depth of field, just a little bit is in focus. If you have a deeper or larger depth of field than more is going to be in focus. But here's the thing. How do you know, looking through the camera, how much is actually in focus. As you're changing your aperture, which is what's going to affect your depth of field, how do you really know what you're looking at? Well all DSLRs have something called a depth of field preview button. And what happens when you push that button is the aperture physically stops down inside of the lens restricting the amount of light, but also changing the depth of field.
Now, when it does that, it does make it harder to see things, because if the aperture goes down to a really really small hole, not as much light's coming in, and therefore it's, you know kind of harder to see what's in there. But if you look closely, you can see what's in focus. So let me show you where the depth of field button is, on a lot of cameras. On Cannon models you will separately find it to the left of the lens just at the base and it's almost always unmarked. So, on this camera it's this little button here. So, while you are holding the camera if thumb will fall right on it and you can point and push the data field preview button to stop that down. On a Nikon camera it's on the other side, you'll see it's over here to the right of the lens but again at the base and again it's also unmarked. This might fall right under your pinkie or perhaps your ring finger. So we just pick up the camera, and push that button to stop the lens down. On the Sony camera you'll find it in the same place as the Nikon. To the right of the lens just at the base and again unmarked. Chances are in your DSLR it's either on the left or the right and again it's probably an unmarked button.
