Technical Terms in Videography
1.Aperture:
Definition: The opening in the lens that controls the amount of light entering the camera. It affects the exposure and depth of the field.
Example: A larger aperture (f/1.8) lets in more light and creates a shallow depth of field, while a smaller aperture (f/11) results in more depth of field.
2. Shutter Speed:
Definition: The length of time the camera's shutter is open to expose light to the sensor. It affects motion blur.
Example: A faster shutter speed (e.g., 1/1000s) captures sharper images, while a slower speed (e.g., 1/30s) creates motion blur.
3. Frame Rate:
Definition: The number of frames captured per second (FPS).
Example: Standard video is usually shot at 24fps or 30fps, but higher frame rates like 60fps are used for slow-motion effects.
4. ISO:
Definition: The camera’s sensitivity to light. Higher ISO values can be used in low light but may introduce grain or noise.
Example: ISO 100 produces cleaner images in bright light, while ISO 3200 might be used for dim settings, though it can increase noise.
5. White Balance:
Definition: Adjusting the colour balance of the footage to ensure that white objects appear white in different lighting conditions.
Example: Tungsten light (orange) will need white balance correction to look neutral on camera.
