Memories that we have. The happiness that we did. All actions happened. It can capture by a magic thing called Camera. If you want to be a photographer. Stop dreaming! Make it happen!
Getting start in the world of photography can seem overwhelming. Your digital camera has more buttons, dials, and menu options than any person can reasonably be expected to keep track of.
There are really only three things that you need to learn to understand photography. Once you understand these three basic elements, and how they relate to each other, you’ll only be limited by your own creativity and desire to practice. These things are:
- Shutter Speed
- Aperture
- ISO
Shutter speed
Shutter Speed is the duration that the shutter is open, and as you’d expect, the longer it stays open, the more light is able to get to the sensor. If the shutter stays open for 2 seconds, twice as much light gets through as if it were only open for 1 second, for example, and 1/2 of a second lets in twice as much light as 1/4. Since the sensor is exposed to light for as long as the shutter is open, it records an image of how far the subject moves during that time. So a 1 or 1/2 second shutter speed will record a blurry image of a moving person. On the other hand, even the fastest person can’t move very far in 1/1000th of a second, so that shutter speed will be great for stopping action.
Aperture
If you look into an SLR lens, you’ll see a set of blades that form a hole in the middle to let light pass through. That hole is the aperture, and the lens can move those blades to make the hole smaller or larger. The larger the hole, the more light gets through, obviously. Your camera’s aperture control, then, is another way to change how much light gets to the sensor. Changes in the aperture also change how your photos look. It can make more blurry effect on your subject background and that effect called Depth of Field.
ISO
ISO is slightly less obvious as the above two as to what it is and what role it plays, but has just as much importance in determining correct exposure. ISO is normally measured from 100, 200, 400 etc., with a low a number as possible preferred. This is because the higher ISO that is used, typically the more ‘noise’ you get on an image, where an image is not as sharp as in the lower ISO’s.
Whether your image is usable or not at high ISO’s depends on your equipment, obviously the more modern cameras such as the Canon 5D Mark 3 produces some excellent results even at high ISO’s such as ISO 12,800.
