A data transfer rate of 1x equals? |
150 Kbps |
|
|
Why is a camera's processor speed important when considering memory card write speeds? |
The processor must be able to write at the speed listed on the memory card. If it can't write as fast it doesn't make sense to buy a faster card. |
|
|
Raw files contain what? |
Minimally processed picture data from the camera's image sensor. |
|
|
What are the three parts of the photographic triangle? |
ISO, shutter speed & aperture |
|
|
A number corresponding to a specific opening in the lens is an? |
f-stop |
|
|
A small f-stop number means the lens opening is? |
Larger |
|
|
A large f-stop number means the lens opening is? |
Smaller |
|
|
The size of the lens opening (aperture) controls what? |
The volume of light reaching the camera's sensor. |
|
|
An f-stop is a fraction indicating what? |
The diameter of the lens opening (aperture) |
|
|
Elements of the f-stop Example: f/4 |
Lens focal length / the stop in use = diameter of actual lens opening |
|
|
Descending from one aperture opening to the next is called? Example: f/4 to f/5.6 |
Stop down |
|
|
Each stop down does what to light entering the lens? |
It cuts the light in half. In reverse, the light gets doubled. |
|
|
Each halving or doubling of light is referred to as a? |
Full stop |
|
|
What are some common full stop f-stops? |
1.4, 2.0, 2.8, 4.0, 5.6, 8.0, 11.0, 16.0, 22.0 & 32.0 |
|
|
Aperture is what? |
Hole or opening inside the lens that either increases or decreases the volume of light passing through the lens into the sensor. |
|
|
Shutter speed controls what? |
How long the volume of light coming through a lens is allowed to stay on the sensor. |
|
|
Shutter speed is measured as a? |
Seconds or as fractions of a second. |
|
|
A faster shutter speed does what? Example: 1/250 or 1/2000 |
Faster shutter speeds decrease the amount of time light enters the camera. |
|
|
A slower shutter speed does what? Example: 1/30, 1/15, 1/8 |
Slower shutter speeds increase the time light enters the camera. |
|
|
A slower shutter speed does what? Example: 1/30, 1/15, 1/8 |
Slower shutter speeds increase the amount of time light enters the camera. |
|
|
How does a fast shutter speed effect motion? |
Faster shutter speeds "freeze" motion. |
|
|
Aperture is a vital component in determining what? |
Depth of field |
|
|
What factors influence depth of field? |
The focal length of the lens, distance between you and the subject and the aperture. |
|
|
Achieve a greater amount of detail or sharpness in an exposure requires what size aperture? |
A smaller opening, larger f-stops. |
|
|
How does a larger aperture opening, smaller f-stop, effect the sharpness in a photo? |
The focused subject will be sharp while other objects will be out of focus |
|
|
Unfocused light records? |
Out of focus shapes. |
|
|
Think of depth of field as |
Sharpness |
|
|
A narrow depth of field will render a ______ background. |
Out of focus |
|
|
Stopping down a lens means? |
Shifting from a smaller aperture number to a larger number thereby reducing the opening's size and reducing the amount of light |
|
|
A greater depth of field will render more? |
Sharpness |
|
|
How does the lens focal length impact a shallow depth of field? |
A lens can focus on one thing at a time. Other objects, depending on their distance from the focus subject will be more out of focus. |
|
|
3 aperture choices |
Storytelling, small apertures Isolation, large apertures Who-cares, average apertures |
|
|
Storytelling compositions use small apertures (f/16 to f/22) and provide? |
Sharp, greater depth of field from front to back |
|
|
Isolation compositions focus on a single object while _____? |
Intentionally leaving other objects out of focus |
|
|
Telephoto lenses have inherently _______ & _____ |
Narrow angle of view & shallow depth of field |
