Color Part I Flashcards
What is color correction?
The process of making the image appear as it did on set (objective).
What is color grading?
The process of giving the image a creative look (subjective).
What is a primary correction?
A correction that affects the entire image (global).
If you add two complementary colors together what color do you get?
A perfect neutral.
Where do complementary colors lie on the color wheel?
Directly opposite from one another.
What is a secondary correction?
A targeted correction that affects only part of the image.
If you want to remove red from a shot which hue do you need to add?
Cyan, the complementary color of red
What do the scopes do?
They analyze color and tone within an image.
If you want to remove magenta from a shot which hue do you need to add?
Green, the complementary color of magenta
Why do we need to use scopes and not just our eyes?
Our eyes are adaptive to color and susceptible to cone fatigue. We use the scopes in conjunction with our eyes to make more accurate decisions.
Is a shade of gray absolute in its appearance to human vision?
No. It is influenced by surrounding tones and colors and can appear wildly different under certain circumstances.
If you want to remove blue from a shot which hue to you need to add?
Yellow, the complementary color of blue
What does graticule mean?
It is the information overlay on the scopes.
What does this highlighted line in yellow indicate?
This is the broadcast safe line.
What is trace?
It is the tonal and color data that appears on the scopes.
What can midtones control?
The mood
What is black point?
It is the darkest part of your image.
What is white point?
It is the brightest part of your image.
If you want to remove cyan from a shot which hue to you need to add?
Red, the complementary color of cyan
What does ‘0’ indicate on the waveform scope?
100% black
What does ‘100’ indicate on the waveform scope?
100% white
If you saw a vectorscope appear like this, what would that indicate about the image?
It would be grayscale or black and white. There is no visible trace except for a default spec in the middle.
What does the highlighted line in yellow indicate?
The skin tone line. Regardless on race, the skin should fall on or around this line in normal lighting circumstances.
If you want to remove green from a shot which hue do you need to add?
Magenta, the complementary color of green
What are the four functions of this scope?
1) Indicates the hues within the image 2) Indicates saturation levels 3) The skin tone line aids in correcting skin tones 4) It can help indicate white balance for a scene (the trace would be centered) that has an even distribution of color with a fair number of neutrals
If you want to remove yellow from a shot which hue to you need to add?
Blue, the complementary color of yellow
In the shadows, what color is likely creating a color cast?
Red. It is raised higher than green and blue, meaning there is more red in that region.
What is the function of the waveform scope?
It measures tonal information within the image.
Color curves: what does Hue vs. Sat mean?
You can choose a hue range and adjust its saturation.
What is a gray card used for when filming?
It can be used to white balance the camera, and when filmed, it can give the colorist or editor a known neutral to white balance the shot in post.
What kind of contrast does this waveform suggest?
Low contrast. The tonal information only occupies a narrow range in the scope.
What kind of contrast does this waveform suggest?
High contrast. The tones occupy the entire range of the scope.
In the highlights, what color is likely creating a color cast?
Green. It is raised higher than red and blue, meaning there is more green in that region.
In the highlights, what color is likely creating a color cast?
Magenta. Green is lower than red and blue, meaning there is less green. The reduction of green past a neutralization level indicates a magenta cast. Green and magenta are complementary colors.
In the shadows, what color is likely creating a color cast?
Cyan. Red is lower than green and blue, meaning there is less red. The reduction of red past a neutralization level indicates a cyan cast. Red and cyan are complementary colors.
Color curves: what does Hue vs. Luma mean?
You can choose a hue range and adjust its brightness.
In the shadows, what color is likely creating a color cast?
Blue. It is raised higher than red and green, meaning there is more blue in that region.
Color curves: what does Hue vs. Hue mean?
You can choose a hue range and adjust the hues.
