aperture
controls amount of light entering the camera
F-stop
the number for aperture; f-stop= focal length/diameter of the aperture (open up/close down)
common f-stops
f/2.0, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22
what does a small f-stop do to the camera?
wider aperture= more light = shallow depth of field (blurred background)
what does a larger f-stop do to the camera?
smaller aperture= less light= larger depth of field (more of the image in focus)
what is Shutter speed?
aka exposure time; amount of time the camera sensor is exposed to light for each frame; shutter speed = fps(frames per sec) x 2
standard motion (shutter speed)/ normal speed
24 frames per second (23.98) (24 x 2 = 48 (1/48))
what should you set shutter speed to?
48 (1/48)
purpose of slow shutter speed
lets a lot of light in, blurred
purpose of fast shutter speed
sport mode, clear images (hummingbird can be captured)
ISO
the film’s sensitivity to light
High ISO
more sensitive, more grain, low-light conditions (1600, 3000)
What is standard ISO
800 (400 is also kinda standard)
Low ISO
less sensitive, less grain, for bright conditions (clearer image) (100, 200)
what is Color Temperature measured in
Kelvin
Tungsten bulb (indoor lamps) temperature
around 3200K (warm and orange)
Daylight temperature
around 5600K, (cooler and bluer)
Frame Rate
number of frames per sec
Standard frame rate
24 frames per second (fps)
Fast motion frame rate
12 fps
Slow motion frame rate
48 fps, 60 fps, 120 fps
Neutral Density Filter (ND)
reduces the amount of light that enters your lens, adds depth
ND stops (the numbers)
ND .3 (1 stop)
ND .6 (2 stop)
ND .9 (3 stop)
ND 1.2 (4 stop)
Resolution
how much detail the image has, based on the number of pixels recorded by the camera
