Aperture • physical light
A lower f-number lets in more light at the same shutter duration. At 14mm, this lens can open to f/4.
CAMERA LAB / CONCEPT LESSON
Frame rate: capture and playback are separate
Capture rate tells you how many frames are recorded each second. Playback rate tells you how quickly they are shown.
Canon EOS R50 VRF-S 14–30mm Verified endpoints
How the pieces connect
50 FPS capture played at 25 FPS runs at half speed. Played at 50 FPS, it runs in real time with more temporal samples.
Apply it to your camera
Use Full HD 50 FPS for the verified higher-rate example. Set shutter duration separately; 1/100 s is an optional 180° starting point.

What these settings change
Shutter • time collecting light
Each frame collects light for 1/50 second. A longer exposure collects more light and more movement.
ISO • output brightness
ISO 400 changes output brightness, not incoming light. With little captured light, noise can become easier to see.
