If you are just starting photography, you have definitely heard of DSLRs. They are the most popular type of cameras among photographers.
They have a lot of buttons and dials on the outside, but have you ever wondered what goes on on the inside?
If so, you’ve come to the right place. Today, we’ll be talking about DSLRs and what makes them tick.
What is a DSLR?
DSLR stands for Digital Single-lens Reflex. DSLRs are digital cameras which use mirror prisims to reflect light from the lens, to the sensor.
How does a DSLR work?
Light passes through the lens of a camera, and hits the sensor. In a lens, there are several glass elements which focus the light on the sensor. The type of image you will get depends on the type of lens you are using.
If you are using a zoom lens, you can adjust the magnification of your image with the zoom ring found on the lens.
On many lenses, you will find a focus ring. With this, you can determine what part of your photo will be in focus. This is particularly useful when doing things like portraits or landscapes.
All lenses have an aperture inside them. The aperture controls the amount of light that comes in contact with the sensor.
If your aperture is wide, more light will get to the sensor from various angles. This produces shallower depth of field in your photos.
Your subject will remain in focus, while the background will be out of focus.
On the other hand, if your aperture reduced, light will enter the sensor directly. This means that both your subject and the background will be in focus.
