Hola! I'm Joey Gunz. You can check me out on line at joeygunz.com. Well we've talked about artistic control and the digital SLR camera. One of the key aspects of taking artistic control with your SLR camera is understanding your camera's aperture. Now your aperture is the iris; kind of like the iris you have in your eye and it opens and closes based on the way that you set it and it controls how much light falls onto your film or image censor on your digital camera. Now your aperture plays a vital role in controlling the depth of field that you get inside your photograph. Say Joey, what's that to feel. What is this depth of feel thing you are talking about. Well what I am going to do is I am going to ask that you zoom in with me and we are going to go on this ride and we are going to show you, get in here, how an aperture works and how an aperture controls depth of field. Now if you take a look here you will see that I've got a lens right here in front of me. I'm going to put it right here and when I have this aperture opened all the way up, on your camera it will give you a very very shallow depth of feel. It means a light of light is coming through. When I say depth of field, we are talking about the distance between what is in focus and far from the camera what is out of focus. That aperture opens and closes like the aperture in your eye. You see that . I can even look through there. Let me give you a real world demonstration. A shallow depth with a wide open aperture. Right now I am in focus. This closeup is in my contract. Have to get this close up in here so I can do my thing. If you take a look at mono light way in the back there, it is out of focus. Now what we are going to do is a shift focus. We are going to shift and put that focus on to that camera in the back and it will give you an example of how shallow of depth the field works. You can only have one thing to focus at a time with a shallow depth of field. Imagine how you can use these and implement it in your photography to create different illusions to create different artistic effects. So aperture, remember aperture controls the amount of light that lands on your subject and it is going to help you create that shallow depth of field or that infinite depth of field where you bring everything into focus.
