Join Chris Orwig for an in-depth discussion in this video Changing brightness with Luminosity blending, part of Photoshop for Photographers: Lighting Effects.
You know, there are so many different things we can do with blending modes in Photoshop and here in this movie, we're going to have some fun taking a look at another blending mode, which is called Luminosity. And here we'll create a black and white adjustment layer, change the blending mode to Luminosity, in order to be able to change the density or the brightness of different areas of this photograph. We'll also create a final adjustment layer in order to finish this project off. This is a picture of one of my favorite places in the world. One of the things that I want to do with this photograph is I want to have some fun with it, and kind of bring out some of the colors, in particular, I want to darken the sky.
One way to do that is to click on our black and white Adjustment layer Icon here in the Adjustments panel. Now as you may be familiar with this, what you can do here is you can change the density or the brightness of different areas of the photograph. For example, we can brighten or darken the sky. The only problem is, all of these adjustments and these areas that were affecting, require that the image is in black and white unless of course, we change the layer blending mode. Let's go ahead and do that. Here we have the black and white adjustment layer, we'll change the layer blending mode to luminosity.
What luminosity allows us to do is to see through the content of this layer so that it's primarily affecting the brightness value of the underlying layer. And because of that, it removed all of that black and white issue that we have here. Yet now, we can use these sliders, in this case, the blue slider in order to darken the sky and create a much more interesting sky than we had previously. Take a look. Here's the before. And then now, here's the after. We can also target the different areas as well. Perhaps, we want to go for a little bit more of an infrared look.
We can really brighten up the greens that we have there in the foreground. And just have a little bit of fun with the overall look in the photograph. Well now that we've accomplished that, here's before, and then here's after. Let's finish this off by applying a curves adjustment. Here we'll click on the Adjustment layer icon for curves. And in this case I'm going to darken the overall image up, we'll create that S-curve that we've talked about before. So I'll drag a point down in the darker area over here, and then in the brighter tones, we'll just drag that S-curve up in that area so we have this slight S-curve which gives us some nice contrast and also color saturation.
Now this isn't necessarily photo realistic, but it is kind of fun. And sometimes when you're working in Photoshop, you can make adjustments like this just to create different looks in your pictures. Here's the before and then here's the after. In other situations, you may use techniques like this perhaps on a lower intensity. Here I'll just take my opacity way down, so I just have a real. Subtle version of that. Here's the before and after, and you can see how we're affecting those areas in this way. So again, really, how far you push the sliders is up to you.
You do need to be careful because sometimes when you push the sliders really far and make those extreme adjustments, the image can fall apart in certain areas, so just keep an eye on that. Yet nonetheless, it's yet another way to be able to modify the tonality that we have here in out photographs by creating adjustment layers. And then by changing the adjustment layer blending mode to luminosity, so that it's primarily affecting the brightness value of the colors which its affecting underneath And then of course, we finish this one off by creating a simple curves adjustment just to add a little bit of snap to the overall photograph.
