Whether you practice photography as a profession or as a hobby,
you would be able to get the maximum out of photography only if you
understand how photography works. You should have thorough knowledge of
aperture, sensitivity, shutter speed, and focal length to take great
looking shots. The following tips should help all amateur and
professional photographers equally.
• The first element that a
photographer should know is aperture. The aperture is the opening of the
lens to allow adequate light to the sensor or the film in the camera.
If the aperture is wider, more light passes through the lens. The
aperture size gets regulated by the fins that encroach from the edges of
the barrel of the lens. If large amounts of fins encroach into the
barrel, you obtain a narrow opening like f/16, f/18, etc. Smaller
numbers like f/3.2, f/2.8, etc. means a wide opening, with only smaller
amounts of the fins obscuring the light.
• When you change the
aperture, it has a dramatic impact on the quantity of the light that
enters the camera. You should not use aperture as a method to compensate
poor lighting. When you shoot landscapes with narrower apertures like
f/22, you have to increase the exposure time. You should use a tripod
for such shots to avoid any blur in motion due to shaking of your hand.
