- Most lenses are sharpest closed down to how many stops from the widest?
- What do the bars on the left of a histogram represent?
- When buying a lens hood, you should get it in what size relative to the lens?
- Why is depth of field greater on a short lens versus a long lens?
- When the additive primaries are mixed together equally, what is created?
- a 1 or 2, depending on the lens, could be 2 to 3.
- b Relative aperture. The opening on a long lens must be larger than a corresponding opening on a short lens to produce the same f-stops.
- c Black (0)
- d It should match the focal length. Too wide and it's inefficient; too narrow and it will vignette; most likely the vignette would occur with wide angle of 28mm and below.
- e White (additive primaries are Red, Green Blue)
5 Multiple choice questions
- Add cyan
- Intensity (aperture) x Time (shutter)
- Sensor size - the larger the sensor size, the longer the focal length of a normal lens. (Corresponds to a diagonal line across the frame)
- Selecting portions of the image based on color
5 True/False questions
Bit depth refers to what? → The amount of information contained in each pixel
When the subtractive primaries are added together equally, what is created? → Black. Subtractive primaries are Magenta, Yellow, Cyan
True or false - a tonal correction can be accomplished by using a hue/saturation adjustment layer → False.
In short lighting, where is the main light placed? → To strike the side of the face away from the camera.
A normal (or standard) focal length lens approximates what? → Selecting portions of the image based on color
