Understanding Photography Basics.

There are certain basics of photography that one needs to master before taking a step ahead in photography. 
When they were first introduced, digital SLR cameras were enormously expensive and a tool for professionals only. Since then, they have come down in price into the consumer price range. Because of this, many people buy digital SLRs without understanding how they work -- and, consequently, not making the most of them. This article will guide you through the most common functions they have, and show you how to learn to use one by experiment. The principles herein are the same for any camera, but you will probably not be able to set your shutter and aperture manually on most non-SLR cameras.


Our Biggest Enemy "The Auto Mode".

Today, most cameras, either film or digital, are equipped with so much automation they promise to do it all for you, allowing photographers to concentrate solely on what they wish to capture. “Just keep this dial here set to P and fire away! The camera will do everything else,” says the enthusiastic salesman at the camera shop. Oh, if that were only true! Chances are that most—if not all—of you who are reading this article have a do-it-all-for-you camera, yet you still find yourself befuddled, confused, and frustrated by exposure. Why is that? It’s because your do-it-all-for-you camera is not living up to that promise, and/or you have finally reached the point at which you want to consistently record creatively correct exposures.
The do-it-all camera often falls short of its promise, yielding disappointing results. Use your camera’s manual settings, or at the very least, know how light and shadow interact on film or digital media so that you can be assured of getting it right even when you are in auto exposure mode



Setting and Using Your Camera on Manual Exposure
 
I know of no other way to consistently make correct exposures than to learn how to shoot a fully manual exposure. Once you’ve learned how to shoot in manual exposure mode (it’s really terribly easy), you’ll better understand the outcome of your exposures when you choose to shoot in semi- or full auto exposure mode.
With your camera and lens in front of you, set your camera dial to M for manual. (If you’re unsure on how to set your camera to manual exposure mode, read the camera manual!) Grab your kid or a friend to use as your subject and go to a shady part of your yard or a neighborhood park, or if it’s an overcast day, anywhere in the yard or park will do. Regardless of your camera, and regardless of what lens you’re using, set your camera dial to M Mode and the lens opening to the number 5.6 (f/5.6). Place your subject up against the house. Now, look through the viewfinder and focus on your subject. Adjust your shutter speed until the camera’s light meter indicates a “correct” exposure in your viewfinder and take the photograph. You’ve just made a manual correct exposure!

  1. Shanky, I have a question. How does camera in M mode indicate the 'correct' exposure ? Are you referring to the image graph ?

  2. The image graph is called a histogram. I'll make a separate post about it. Not all cameras have a live histogram.
    When we look into the viewfinder we find a number of indicators flashing.

    Please refer to the above image.
    The [-2..-1..0..1..2] is a exposure level indicator. When its on 0 the camera thinks exposure is correct.
