Settings


Booooooorrrring....... to quote Mindy when she was 14....

Owners manuals are a drag, but surprisingly useful from time to time. But they are not known for their riveting prose, or their story line. Remember the Manual in "Beetlejuice?" "This reads like stereo instructions..."

I'll try to make a little sense here of those little icons on the dial or screen of your camera.

Every camera is a little different, so I'll stick to the basics,

First, is automatic. This assumes you have no brain, and are only barely capable of pressing one button. The camera does everything for you except aim. It determines whether you need flash, how to focus, what your exposure should be, whether your hands shake, and if you've had too much coffee.

Ok, yours might look a little different...
Automatic has some uses, particularly in those spur of the moment instances, where if you have to think, you will lose the moment, and the shot. But in most cases, I avoid automatic. But not coffee.

Second, and more useful is "P" or Program Automatic. We are slowly taking control over from the little computer in the camera. We can determine whether to use flash or not, and we can compensate for the overall brightness of the images. The camera wants to see an "18% Gray" image. The palm of your hand is a good approximation of the brightness of 18% gray. But what if you are shooting on a sunny day in a snow covered field? The camera will try to average the scene at 18% gray, making it look muddy. In this case, you can tell the camera to overexpose the image. The reverse is true for dark scenes.

Now we get to the icons, or little pictures on the wheel. The little face is "Portrait Mode", which adjusts the camera to blur out the background while keeping your subject in focus. Yes, the camera is still thinking for you, but you are telling it to think in a very specific way.

The little icon of the mountain does exactly the opposite of the portrait mode. It tries to get everything in the viewfinder in focus from the extreme foreground to the distance. It does this by making the aperture smaller, and increasing the ISO (sensitivity of the sensor).

The flower icon means "Macro" mode, or extreme closeup. It allows you to take very crisp images very close to your subjects.

The Sports icon tries to get clear images of things that happen very fast, like hockey or lacrosse.

I have to admit, I don't use those settings, except "P", but it is good to know what they do.
My goal for you, is to have you thinking for yourself, rather than depending on a thumbnail sized electronic brain do it. But while you are learning, play with these settings, see what they do and how they affect the images you take.

Next week, we'll play with "Depth of Field". I promise it will be riveting!
