It brings up a little menu here and the top option is ISO (in a lot of cameras the top option is ISO). Now you have a lot of different choices here, a lot of different numbers. The lower the number the more it’s going to saturate color but also the more light that it’s going to require.
So I shot this picture inside a cave and I shot it at eighty ISO. And you can see that in the cave there’s not a lot of light. So since this takes a long time to soak up light the picture came back a little blurred. Now I did the same shot again and I brought the ISO up to four hundred. And as you can see with this picture, it fixed the blur because it soaks up the light quickly and takes a good image. But you’ll also notice when we zoom in close to this, there is more grain because this image has been amplified.
All right now, let’s talk about aperture. Now what aperture does is it governs the depth of field. Now here we’re looking through a lens here. This is you know from a professional Nikon camera but it’s similar to what you have on your compact digital cameras. Now right now you can see that it’s wide open on the inside. That’s a large aperture like a big O, usually like an f2 or an f1.
Now what this does is it lets a lot of light come through the lens so you get a very short depth of field to blur that background, so your subject is in focus and really stands out. Now look when you make your aperture higher, it makes it very small like this, so that it lets a little bit of light through. Now what this does is it gives you a great depth of field, which is great for landscape pictures, mountains, scenery, things like that in nature, when you want the background and the foreground to be in focus. All right now here’s how you set your aperture value. Lot of these little cameras have this wheel on the top, which makes it very easy and I know you’ve seen these letters and wondered…what do these mean? So you just stay on auto. Well it’s time to move away from auto.
This Av that stands for aperture value. You get to set your aperture to control the depth of field and right here on the bottom is a number corresponding to the aperture. Now that’s a 2.8, which means it’s very open, it’s going to let a lot of light in and make the subject in focus and the background blurred. Now if you wanted to change it, if you want to take a landscape picture you can move it up. On this Canon it’ll go up to 8. Some cameras go higher 15, 20 even. And this is good for landscapes and that sort of thing.

Digital Camera Basics-Images
In the past twenty years, most of the major technological breakthroughs in consumer electronics have been built around the same basic process: converting conventional analog information (represented by a fluctuating wave) into digital information (bina…
