The Camera - Focal Length and Frame Rate

 

FOCAL LENGTH

What is focal length

The focal length is the length of the lens is the difference between the lens and the focal point, this is usually controlled by the length of the lens.

What is the difference between a low mm lens and a high mm lens

a short low mm lens will give you a short wide-angle, a large mm lens will give you a more narrow field of view

When do you use lower/higher focal lens

Because lower mm focal Lenses give you a wide angle they are very landscape photography where you would want to capture a large portion of land from a distance. the higher focal lenses are generally better for catching very detailed images of a subject and can be useful in things like wildlife photography where the subject is often far away.

FRAME RATE

What is fps

framerate is dictated by how many pictures your camera takes per second or the FPS. so at a number like 24 fps your camera is forming a video with 24 pictures or taken every second leading to there being 24 frames every second of the video.

Advantage of using high framerate

With a high framerate footage can be slowed down more effectively because of all the frames for every second.

cinematic look frame rate

24 fps is the cinematic framerate in America and because most people are used to it in movies it looks natural to film things in 24 fps.
