Photoshop has a built-in filter system that you can use to adjust the appearance of your images. You can adjust things like brightness, contrast, saturation, and hue.
In Photoshop CC 2020, there is a filter called “Luma Filter.” This filter can be used to adjust the brightness of an image. To use the Luma Filter, you must first create a new layer. Then, select the “Luma Filter” from the Filters palette and click on it.
