Umgang mit den Folien
- Navigiere mit den blauen Pfeilen rechts unten oder über das Menü links unten
- Tastatur: "Escape" für Folienübersicht, "f" für Fullscreen; "s" für "Speaker Notes", Pfeiltasten zur Navigation, u.v.m. (mehr: "?" für Hilfe)
- Mobilgerät: Navigation per Swipe-Gesten möglich
- Es gibt horizontale und vertikale Folien (erkennst Du an den blauen Pfeilen oder in der Folienübersicht)
Camera
|||
Framerate
Captured pictures/frames per second - FPS
-
Capture framerate is set in camera and can be changed to create effects like slow motion in playback
-
Playback framerate is set in the editing software and detemains at wich speed the frames are played back
-
normal motion: capture framerate 30fps and playback framerate 30fps -> 1x speed
-
slow motion: capture framerate 60fps and playback framerate 30fps -> 0,5x speed
-
fast motion: capture framerate 15fps and playback framerate 30fps -> 2x speed

Common framerates
*Maximum sensor frame rate dependent on resolution and codec selected. Project frame rates of 23.98, 24, 25, 29.97, 30, 50, 59.94 and 60 fps supported.
Off-speed frame rates up to 60 fps in 6K 2.4:1, 120 fps in 2.8K 17:9 and 1080HD.*

Exposure
|||
Shutter
Shutter angle vs shutter speed
- 180° shutter angle -> "Normal"
- Large shutter angle -> increase motion blur
- Low shutter angle -> decrease motion blur
|||
Aperture
f-Stop on Photography lenses
|||
ISO
- Low ISO -> less sensitivity to light
- High ISO -> more sensitivity to light (but more digital noise)
Lenses
-
Prime lense with a fixed focal length. No Maginification of the image but a faster apterture.
-
Zoom lense with an alternating focal lenght.
-
Canon EF 24-105mm f/4,0 L IS II USM
-
Canon EF 16-35mm f/4,0 L IS USM
-
Canon EF 100mm f/2,8 L Macro IS USM
-
Canon EF-S 15-85mm f/3,5-5,6 IS USM

Focal Length
common focal lengths for wide lenses: 18mm, 24mm, 35mm -> less magnified common focal lengths for tight lenses: 85mm, 100mm, 135mm -> more magnified
a focal lenght of 50mm is concidered a standard lense equal to the human eye.
long focal length compresses the background and helps isolating a subject.
