If you want to increase the luminosity of an image in Photoshop, there are a few different ways to go about it. One way is to use the Levels tool. To do this, first make sure that the Image layer is selected and then click on the Levels button (located in the Layers panel). The Levels dialog box will open. In this dialog box, you can adjust the brightness, contrast and color levels of your image. To increase the luminosity of your image, click on the Luminosity slider and drag it towards the right. You can also use these same settings to adjust the brightness, contrast and color levels of individual colors in your image. Another way to increase the luminosity of an image in Photoshop is to use one of Photoshop’s filters. There are a number of filters that can be used to achieve this effect, including Gaussian Blur, High Pass Filter and Sharpen Filter.
