In our last lesson, in our look at learning DaVinci Resolve, talked about working with Windows, and how you can use them to isolate parts of your shot. In this lesson, I want to move on and talk about Qualifiers, and how you can use them to do secondary color correction inside of Resolve.
The first thing that’s important to understand is, what is secondary color correction? Think of it this way. Primary color correction deals with the fixing of colors across your entire image. Secondary Color Correction is when we’re going to adjust the color in one specific color in our shot. Now, keep in mind that this is where we’re going to star combining concepts that we’ve learned through this series. If you have different areas of a shot that are the same color, you can start to use Windows to isolate the specific color or area of the shot, to “garbage matte” the area you want to focus on.
Let’s make sure we have a shot to correct in our timeline, and then head to the Qualifier section of the Color Module.
Once there, we’re going to use the Color picker to isolate the color we want to adjust. In our case, we’re going to use the color of construction workers helmet
Once we have selected the color, it will look like nothing has happened, but if you look at the Node window, or head to the upper left corner of the Timeline Canvas, you can turn on the “Highlight” command to see only what has been “keyed” out in your image.
Keep in mind that this is essentially what you’re doing with Qualifiers. You’re keying the color that you want to make a color adjustment to, and if there’s more than one variation of that color in your frame, you can use Windows to isolate (garbage matte) the specific region you want to focus on. Now, if you want to go in and clean up, or adjust the matte, you can use the tools in the Matte Finesse section to Add or remove shades of the color, adjust feathering, shrink, and clip (to name a few) that matte, to get the exact look that you want. Now that we’ve isolated our color, any color correction we do to our image will only affect that specific color, and not anything else in our shot.
