Step 7: In this case, my Input number is about 213, which in mathematical expression indicates the lighter parts of the image. Then with the Eyedropper tool, I look for lighter parts in my image that could look better without a red color cast. In order to adjust the red color cast, I have to switch from the Blue channel to the Red channel. Step 6: Next, I adjusted the yellow color cast however my image now looks too red especially in the lighter parts. To add blue color to my image, I need to change the Output number to higher than 51. Since the image is too yellow I need to add blue to make it neutral. With my Eyedropper tool, I pointed to one of those parts and my Input number in the Curves palette pointed to 51. Step 5: Yellow color cast was mostly visible in the darker parts of my image.
That is why my next step is to change the RGB channel to Blue channel. As I explained before, yellow corresponds to Blue channel. I again start my correction by selecting Layer > New Adjustment Layer > Curves and after closer examination I concluded that my image is too yellow.
Step 4: Cool, now allow me to put this theory into action. The higher the Output number in the Blue channel is going to leave a blue color cast over my image and a lower Output number is going to create a yellow color cast. Now, if I lower the Output number extremely, then my image is going to have a magenta cast all over it. If I work in the Green channel, then the higher the Output number is, the greener the image is. That is the concept behind color correction. However, if I lower the Output number to about 80, then our image is going to look like this. Higher Output number in Red channel makes the image too red, and that’s not what I want to accomplish. Let’s see what happens when we change our Output number to about 160. I chose to color correct the image in the midtones and for that reason the Input number is equal to 128 (midtones range from about 128 to about 132). The red dot in the Curves palette represents the position of these numbers. The Input number is a mathematical representation of my color whereas the Output number is a mathematical representation of the color after my color adjustment. On the bottom of my window I have two numbers - Output and Input. In my channels options, I chose Red (for red channel). To better understand how it works, let’s look at it closer. Learn it, remember it! The Curves Adjustment tool allows us to work with RGB channels and their corresponding colors in order to adjust the colors correctly. Each of these colors has a corresponding color on the color wheel therefore, red corresponds to green, green corresponds to magenta and blue corresponds to yellow. Our image is composed of red, green and blue channels (RGB). Step 3: To color correct we need to know a few basic things about color. Now go to Layer > New Adjustment Layer > Curves. Remember to always work in layers instead of applying any adjustments directly to the image. Step 2: In this tutorial, I am going to use Curves Adjustment tool to color correct my image. I always start with cropping and straightening my image and then I go to any further adjustments. Step 1: I like to begin with cropping my image. First of all take a look at the image we'll be creating.
Let’s get to work then! This tutorial will teach you how to use this tool to color correct photos efficiently. I want to color correct my shadows, but I want to leave my midtones unaffected). The Color Balance Adjustment tool gives me limited options when it comes to correcting my images, whereas the Curves Adjustment tool allows me to color correct specific areas of the image without affecting the rest of the image (ex. I use this tool instead of widely used Color Balance Adjustment tool. One of my favorite tools that I use on regular basis is the Curves Adjustment tool, which not only helps me in creating desired contrast, but at the same time it allows me to color correct my images.
With these new tools many users forget about the ever-present tools that are still a standard in the professional field. Each new edition comes with newer tools, more presets and better interfaces which allow beginning users to learn Photoshop quickly and efficiently.
