How To Use Your Camera - The Electronic Analog Exposure Meter

A lot of the people I visit with or coach about how to use your camera have no idea what this handy tool does, or for that matter how to use it. Most will turn it on accidentally, then work like the devil to turn it off again. I intend, as briefly as possible, to help you not only understand what it does but help you use it to your advantage.

Most camera's offer this tool but it isn't always turned on or it only displays when in a certain shooting mode. You may need to spend some time with your manual to figure out how to find and turn the meter on for your camera. The professional-grade cameras make this easier because the pros use this tool a lot. My Nikon D300 displays a meter in the viewfinder and on the control panel. It's that important if you want to have total control over your exposures.

The Electronic Analog Exposure Meter consists of a row of little vertical bars or possibly little dots. An example may look something like this: “+3..+2..+1..0..-1..-2..-3.” This would be a meter graduated to 1/3 steps between each full stop. A meter graduated to ½ steps would display a single dot or bar between each full stop.

The “+” sign indicates an increase in exposure while the “-” sign indicates a decrease in exposure. Exposure is simply the amount of light allowed to reach your film or sensor. It is controlled by either the shutter speed, or the size of your lens opening or “aperture,” usually both. If your meter is indicating an exposure in the + area, more light is being allowed in, if it is on the – side then less light is being allowed to pass. Ideally you should adjust you meter to the center for you first exposure. See how it appears to your eye and your histogram. You can then make adjustments by changing either your shutter speed or your aperture to get the exposure you want.

With your camera in hand and set to manual control or shooting mode, go out and take a few pictures while adjusting the shutter speed and aperture to see how it affects your meter readings and what the images will look like. I will take this topic further in a later post, so be sure to check back for more information about your exposure meter as you continue to learn how to use your camera.

Photography Tips

Here are a few things you can do to improve your photography that will apply regardless of what camera you use. These are the basics that every photographer should know and do to get reasonably good pictures out of any camera.

Make sure you have a clean lens. Don't just blow the dust off, but use a clean cloth suitable for cleaning lenses and do it right.

Set up so your camera is stable and won't move as you press the shutter. You can do this a number of ways. If you will be handholding the camera, hold your elbows in against your sides, and stand with your feet apart with one slightly forward of the other. You can also lean against a solid object like a light pole, tree, building or whatever. The best method though is to use a tripod or monopod. I have both but I like to carry the tripod best. If I want to use it as a monopod I just extend only one leg and us it as I would a monopod. I'll add instructions about to how to use these tools later.

Finally the "First" basic thing you need to do is read your manual and learn what all the parts of your camera are for and how to use them. If you understand how your meter works and what white balence is you'll go a long way to getting that shot you want when the light is wierd and you are wondering why your pictures are all dark or yellow instead of like what you saw on the monitor or in the viewfinder.

I'll expand on all these topics in the coming weeks and months so you'll want to check back and see what I've added from time to time.
