In this tutorial, you will learn just how powerful this tool really is.<\/h2>\n<p>While we&#8217;ll be using DaVinci Resolve in this specific tutorial, the information can be implemented from Final Cut Pro to Photoshop, because the way the curves work is universal \u2014 even if their appearance and functions differ from software to software.<\/p>\n<p>They allow you to make precise luminance and color adjustments to an image \u2014 from slightly raising a specific region of the midtones to drastic highlight changes. At their core, they are a fundamental tool to bring your images to life.<\/p>\n<p>In the video tutorial below, I&#8217;ll run you through the core features of both the Custom Curve and HSL Curves.<\/p>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/ZCI_Ci7y0kk?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<p><em>*While we always provide a written transcript of the tutorial, it&#8217;s recommended you watch the video to see the image reacting to the curve adjustments in real time.<\/em><\/p>\n<hr \/>\n<h3 id=\"custom-curves\">Custom Curves<\/h3>\n<p>Across all software, this is a typical representation of the curve graph.

If you add just one control point, the entire curve will shift with the adjustment, resulting in an overall image alteration.

Well, if you feel like this shot is too warm, and you look at the scopes and see the red value has a larger presence than the blue, you might think: <em>Well, let\u2019s add blue to cool it down.<\/em> When, in fact, you&#8217;d be better served to pull the red out of the shadows by lowering the red curve down.<\/p>\n<hr \/>\n<h3 id=\"hsl-curves\">HSL Curves<\/h3>\n<p>The Custom Curve is just one of six total curve adjustments available within Resolve. The other five being the <a href=\"https:\/\/www.premiumbeat.com\/blog\/hue-vs-curves-davinci-resolve\/\" target=\"_blank\" rel=\"noopener noreferrer\" data-wpel-link=\"internal\">HSL curves<\/a> \u2014 an acronym for Hue, Saturation, and Luminance. So, let&#8217;s briefly run over these curves and how they differ from the custom curves. In total, there are:<\/p>\n<ul>\n<li>Hue vs. Hue<\/li>\n<li>Hue vs. Sat<\/li>\n<li>Hue vs. Lum<\/li>\n<li>Lum vs. Sat<\/li>\n<li>Lum vs. Lum<\/li>\n<\/ul>\n<p>Thankfully, I don\u2019t have to explain how each one works, as even though they operate differently from the custom curve, they all operate identically. However, the operation results will vary from curve to curve.<\/p>\n<p>To understand the practice, let\u2019s have a look at hue vs. saturation. Like the Custom Curve, we have a histogram within the curve graph. However, you&#8217;ll notice that this curve is displayed differently. We have a more elongated graph, with a horizontal curve, with the hue spectrum present.<\/p>\n<div id=\"attachment_143688\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.premiumbeat.com\/blog\/wp-content\/uploads\/2020\/11\/Hue-Vs-Hue1-2.jpg\" target=\"_blank\" rel=\"noopener noreferrer\" data-wpel-link=\"internal\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-143688\" class=\"wp-image-143688 size-large\" title=\"Hue vs. Hue\" src=\"https:\/\/www.premiumbeat.com\/blog\/wp-content\/uploads\/2020\/11\/Hue-Vs-Hue1-2.jpg\" alt=\"Hue vs. Hue\" width=\"755\" height=\"400\" \/><\/a><p id=\"caption-attachment-143688\" class=\"wp-caption-text\"><em>An example of hue vs. hue.<\/em><\/p><\/div>\n<p>The information within the histogram directly represents what is present within the viewer. There\u2019s an abundance of reddish-green and blue in this specific shot, described in the curve graph. Therefore, if I wanted to adjust the blue saturation, I could make two control points around the spike, then increase or decrease that hue. Alternatively, we could move over the preview monitor, and a qualification tool appears. Upon selecting any hue in the image, the corresponding control point will appear in the curve graph, making for a more precise adjustment.<\/p>\n<p>We could increase the green saturation while decreasing blue saturation, all in one curve, all in one node.<\/p>\n<div id=\"attachment_143687\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.premiumbeat.com\/blog\/wp-content\/uploads\/2020\/11\/Hue-Vs-Sat1-1.jpg\" target=\"_blank\" rel=\"noopener noreferrer\" data-wpel-link=\"internal\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-143687\" class=\"wp-image-143687 size-large\" title=\"Hue vs. Sat.\" src=\"https:\/\/www.premiumbeat.com\/blog\/wp-content\/uploads\/2020\/11\/Hue-Vs-Sat1-1.jpg\" alt=\"Hue vs. Sat.\" width=\"755\" height=\"400\" \/><\/a><p id=\"caption-attachment-143687\" class=\"wp-caption-text\"><em>With just one curve, you can simultaneously increase the green saturation while decreasing the blue saturation.<\/em><\/p><\/div>\n<p>And, this works the same way right across the other four HSL curves. Although, the luminance vs. sat and sat vs. sat are slightly different and perhaps more niche in their use. For example, if we pull up the lum vs. sat curve, the graph is now monochromatic, representing the saturation levels from the black to the whites of the image. By adding several control points toward the shadow region, we can decrease the saturation of the darker areas of the image.<\/p>\n<div id=\"attachment_143686\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.premiumbeat.com\/blog\/wp-content\/uploads\/2020\/11\/lum-vs-sat-1-1.jpg\" target=\"_blank\" rel=\"noopener noreferrer\" data-wpel-link=\"internal\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-143686\" class=\"wp-image-143686 size-large\" title=\"Lum. vs. Sat.\" src=\"https:\/\/www.premiumbeat.com\/blog\/wp-content\/uploads\/2020\/11\/lum-vs-sat-1-1.jpg\" alt=\"Lum. vs. Sat.\" width=\"755\" height=\"400\" \/><\/a><p id=\"caption-attachment-143686\" class=\"wp-caption-text\"><em>Decrease the saturation of the darker areas by adding several control points toward the shadow region.<\/em><\/p><\/div>\n<p>So, on just the one node, you could adjust the tonality of the image, increase the saturation of a specific hue, and decrease the luminance of another hue. It\u2019s a powerful tool.<\/p>\n<p>Now, some of the fun with curves come when you start making extravagant adjustments, but lower the node&#8217;s intensity\u2014kind of like lowering the opacity of the layer in Photoshop.
