It is possible to select multiple points along the curve. Think of it as a comparable function to an audio EQ. In other words, how broad of a range of hues that you want to affect for the selected color. These boundary points determine the envelope of your selection. When you sample a color, you end up with three points along the curve – the pin for the selected color and a range boundary pin on either side of that color.
These curve options let you grab a specific color and adjust its hue, saturation or brightness, without changing the tone of the entire image. If you toggle the curves pulldown menu, you’ll notice a number of other options, like hue vs.
Only adjust the R, G or B curves if it’s beneficial to your look. Therefore, make sure to disable ganging before you start. However, this means you are jacking around chroma levels when you might simply want to alter luma. The default is for these to be ganged together. In the custom curves panel you’ll encounter a typical layout of four curves for luma and RGB. This shifts the low and high ranges of the image to expand the signal back to full levels, while retaining a “filmic” quality to that image. Given the propensity of cameras to record with log gamma profiles, you often find the need to apply an s-shaped luma curve during color correction. Hover the mouse over the slider that you want to adjust and twirl the mouse wheel up or down to make your correction. This is great if you don’t have access to a control surface. An added benefit of this panel is that the controls react to a wheeled mouse. Simply move the blue lift slider lower to push the shadows closer to a true black. If the blue shadow portion looks too high on the RGB parade display, it means that the shadows of the image will look bluish. If you adjust color balance using the sliders, while monitoring the RGB parade display and/or the histogram on the video scopes, then it’s very easy to dial in perfect black and white balance for a shot. Adjustments made in either control will show up in the other. Most people gravitate to the wheels control panel, but the sliders panel is often faster and more precise. Resolve gives you two ways to adjust primary color correction – color wheels and sliders.

If you have an understanding of how to use a 3-way color correction filter and you comprehend procedural nodes as a method of stacking corrections, then it’s easy to get proficient with Resolve, given a bit of serious seat time. Even the free Lite version does nearly everything you’d want from any color grading software. Blackmagic Design’s DaVinci Resolve is one of the pre-eminent color correction applications – all the more amazing that it’s so accessible to any user.
