The colors it displays are red, magenta, blue, cyan green, and yellow. The YUV vectorscope displays the hue and saturation of the colors in the image on the circular graph. You have two options with the vectorscope, the HLS vectorscope and the YUV vectorscope. Vectorscopes are another handy visual post-production scope. While we’ve listed this as a production scope, it is also very commonly used in post-production to correct overexposure or “crush” blacks to make them richer and darker. It is most useful for preventing “peaking,” which is when certain parts of an image are too light or too dark, making details imperceivable. This graph only tells you how light or dark the RGB elements of your image are, not about saturation, tone or other color elements of the image. As you can see, there are peaks at the bottom and top of the graph, representing that there are some parts of the image that are very light or very dark, but overall most colors fall within the midtones. This graph shows the distribution of colored pixels within each value of lightness or darkness. Visually, in this example, the darks are at the bottom of the graph and the whites are at the top. This is a representation of the highlights, midtones, and shadows (also called blacks or shade) of your image.įor an 8-bit image (which is standard), pure black has a value of 0 and pure white has a value of 255. Here are the most common scopes used in both production and post-production: Production Scopes HistogramĪ histogram allows you to see the tonal values of your clip. They provide exact representations of what elements make up your image, from color values to lightness, and are your best friend when perfecting everything from skin tones to overall image color. These tools won’t lie to you like your eyes and monitors might. That’s because our eyes are incredibly good at adapting to different lighting conditions, but this built-in talent can work against us when we’re staring at the same shot for hours on end as we attempt to strike the right color balance. This is often due to improperly calibrated monitors, but even with a well-calibrated monitor, your eyes can still deceive you. When you’re editing and color-correcting your latest video project, many editors find themselves “eyeballing” the process, only to discover that once they export their final product, the colors and contrast dramatically shift when viewed on a different device.
