Types of Cameras
•
Compact (Point and Shoot): Small, less expensive and super simple to use.
Most are aimed at beginners, shooting indoors and taking mostly family shots.
•
DSLR: “Digital Single
-
Lens Reflex” have grippable bodies, clear viewfinders,
great battery life, and good value for the money. Models for both
beginners/enthusiasts and experts/pros. They offer high quality images, ability to
use a variety of lenses and have lots of features.
•
Mirrorless: Newer trend. Lighter, compact, better for video than DSLR but
with less lenses and accessories to choose from.
Overview of
how DSLR
Works
• A DSLR system consists of two main elements: the lens and the camera body. These can be interchanged to an extent. Understanding their basic concept is not rocket science. It is explained best by showing the way of light.
• First, light (blue line) hits the lens from the front. Then, it travels through the lens, which shapes it to a form the photographer desires. It then makes its way through the lens mount to the camera.
• Then it encounters the main mirror. The mirror reflects most of it upwards, to the viewfinder. There, a pentaprism or a
pentamirror directs it to the viewer’s eye. This allows you to see exactly what the lens sees.
• In SLRs and DSLRs withautofocus, a small portion of the incoming light actually passes through the main mirror. There, it hits the secondary mirror. This directs it down to the autofocusing sensor.
• In this state, none of the light hits the imaging sensor. This is a key trait of DSLRs.
• When you press the shutter button to take a photo, the mirrors flip up. This enables light to hit the sensor. Because the main mirror no longer reflects anything, there is a blackout in the viewfinder.
• The shutter mechanism, right in front of the sensor, opens up. It exposes the image and closes down after a set amount of time. That time is called theshutter speed.
• After the exposure, the moving parts go back to their previous state.
