Aperture priority is a great mode to use anytime your shooting portraits. A lot of wedding photographers and portrait photographers prefer to use this mode and it’s very simple to use. Turn your mode dial to the A, this stands for aperture priority and what this allows you to do is by using the dial up in the front, you can control the aperture setting right back here. So, right now for example, mine is set at the 5.6, if I roll the dial to the left, the aperture becomes wider and the depth of field in my picture becomes more shallow. So adjust the subject on which I focus will be sharp, everything else will be blurred out. If I roll the dial in the other direction, I’ll make the aperture smaller and now the entire scene will look as though it’s in focus.

You should note this camera is capable of a 3.5 aperture when the lens is at its widest. As you zoom in, you can see that the aperture is changing and if I zoom in all the way, the widest I can have is 5.6. As I zoom back, the aperture will widen because it remembers that I set it to 3.5 earlier unless when I’m zoomed in, I used the dial to change the setting. Now, it assumes I want 5.6 and not 3.5 and as I zoom back, it will stay at 5.6. You do have control of your shutter speed in this mode but you have to use the exposure compensation to access it. With the aperture fixed, if you adjust the exposure compensation by pressing the dial in like a button, you can adjust the exposure compensation by rolling the dial and the shutter is what’s used to brighten the image and the aperture stays fixed.
