Let's tweak the overpowering blues and greens so more. Thus the graph in that corner is now a flatline indicating "No red." This step can be skipped if there is no overpowering areas of red. What I'm directing Photoshop to do is to reduce the red in the darkest parts of my picture. I have too much red in my dark shadows so I'm going to adjust the graph in the bottom left corner.Ĭlick on the bottom left corner and drag it to the right. The graph indicates how much red is in each part of that image between those two bookends. The bottom left corner are the darker spots of our image and the top right corner are the lighter parts of our image. In the figure below, we are looking at a graph of the reds in our picture. Step 4: Still in the Curves Pop Up Window, go to the "Channels" window and select "Reds" in the drop-down menu. In some areas, like the darkest areas of my reef in this photo, the red will go overboard and develop red spots. In our case, it dropped the blues and greens down and raised the red as much as it could. Hopefully, you should see some change in your image. Don't press okay or close the window yet. Step 3: Select "auto" in the Curves Pop Up Window. Remember, the main problem is we don't have enough red. Good, we're going to play with the levels of red, green, and blue in our picture. Step 2: Go to "Image" in the main toolbar-> "Adjustments" -> "CurvesĪ popup window should now appear. Not a lot of things of color so we can't drastically change it, but we can add slight improvements. Here we have a cute little picture of turtles having a morning snack on the sandy reef. You can also see if your improvements are pleasing by clicking the "eye" icon to the left of the layer and you should only see your original background layer. ( Hey, I told you I was going to walk you step by step)Ĭopy the layer that has your picture by pressing "control" and "j." I always like to work off a copy layer so if I screw up, then I can just delete that layer and start over. Here, I will walk you through it step by step. One quick tip is to add a layer, fill it with red, and then change it to overlay.Īnother method is a simple method of using the "Curves" function. Picassa does a pretty great job with the "lucky button." The first thing you have to understand is that as you dive down deeper, the first color to go is "red." This will give all your photos a bluish/greenish cast. There are various ways to fix underwater pictures in photoshop. How do you fix the color in underwater pictures?
