Tint detection
If a vertical movement compared to the other colors is noticed for one of the three
colors, a tint is present. When you regulate the saturation using the video effects, the
result is immediately visible in the "RGB Parade" measuring instrument.
Histogram
The histogram shows the brightness distribution on the image.
X Axis (horizontal): Brightness increasing to the right
Y Axis (vertical): Frequency increasing to the top
Cases for using the histogram
Detect and correct overexposure / underexposure
If too many white portions are present, the right border is white (100% and
digital 255).
If too many black portions are present, the left border is white (0% and digital 0).
Analyze and adjust use of brightness space
When partial areas of the brightness space are not being used, there will be areas on
the horizontal axis with frequency value 0. No curve can be seen at these positions.
