The waveform monitor is used to evaluate the brightness of your image, regardless of the color. The scale of the waveform monitor is 0 to 100 IRE. IRE represents the scale invented by the International Radio Engineers society. Essentially, it is designed to match the capabilities of early televisions to display an image. Anything at 0 is completely black, with no detail, and anything above 100 will be clipped and white, with no detail. Of interest to note about a waveform monitor display, as opposed to a vectorscope or histogram, is that the waveform produces an abstract version of your image; viewing the waveform from left to right mirrors viewing the image from left to right, making it easy to reference the brightness of specific areas of your image/frame quickly.

Take Away: Make sure that the lines are not touching the 0 or 100 lines!

The vectorscope displays six color targets essentially fixed into an odd-shaped pattern on a grid. In fact, each color is represented by two targets, but what is important about the vectorscope is that it displays color information that the waveform monitor does not. In the old days of analog, the vectorscope, along with the waveform monitor, were tools used to align multiple cameras, so that their colors and brightness matched when shooting the same set. Specific color charts were shot, and the technician would adjust the cameras to make sure that red on one camera was the same red on another. This would be done by manipulating the camera electronically to make sure that the known color landed in the center of the target. Even in the digital age, or perhaps especially in the digital age, with productions using a wide variety of cameras with different sensors from different manufacturers, being able to read your camera on a vectorscope is precisely what you need. Getting your colors to align accurately when shooting will save you significant time in post, even if you are only working with one camera.

Take Away: We want the color to look natural. Pay attention to skin tones, make sure we don't have smurfs (blue levels are too high) or demons (red levels are too high).
