PixelsWhat are pixels? The word "pixel" means a picture element. Every photograph, in digital form, is made up of pixels. They are the smallest unit of information that makes up a picture. Usually round or square, they are typically arranged in a 2-dimensional grid.
Setting the Right F-Stop
for Your Digital Photo
• Use an almost-wide-open f-stop to boost sharpness.
• Adjust your depth of field by moving f-stops.
• Avoid too-small f-stops.
Shutter SpeedThe unit of measurement which determines how long the shutter remains open as the picture is taken. The slower the shutter speed, the longer the exposure time.
The shutter speed and aperture together control the total amount of light reaching the sensor.
Shutter speeds are expressed in seconds or fractions of a second. For example 2, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000. Each speed increment halves the amount of light.
• A prefix on film speed ratings that stands for International Standards Organization, the group that standardizes, among other things, the figures that define the relative speed of films.
What makes a good photograph?
Composition
• Rule of Thirds
– The rule of thirds is the simplest rule of composition. All you do is take your frame and overlay a grid of nine equal sections. This means you split the vertical space into three parts and the horizontal space into three parts.
Perspective
• Photographing your subject straight-on is sometimes the right choice, but you can create visual impact by moving the camera left, right, above, and below.
