In this tutorial by Denny's Tips, you'll learn how to achieve the pastel teal and yellow look inspired by Ben Thomas. Although this is a Lightroom tutorial, you can still follow it in Photoshop using the Camera Raw filter (Filter > Camera Raw). This is a quick tutorial that will show you how to create flat tones and shift the colors towards teal, yellow and pink. Because the color changes are so drastic, you have to combine the hue adjustment in both the HSL and Camera Calibration settings. It's an interesting technique that can be adapted to create many other color combinations.
Also mentioned in the video are also 5 presets that you can download for free. Simply copy them to your Develop settings folder and they'll appear in Lightroom's presets panel. These presets work for both Lightroom Classic and Lightroom.
