Your info panel should display values close to these You may follow how we've placed our stoppers by following the example here: Place a color stopper in each of these areas. Take a good look at your image to determine in the areas is closest to pure white, pure black and a gray midtone. While we can visually identify this issue, for precision we are going to use the Info panel to identify the color cast. Outdoor photos tend to have a blue color cast from natural light while indoor photos with incandescent lighting tend to have a yellow color cast. A color cast occurs when a single color is cast over the entire image. We want to improve the greens and browns of the natural background while preserving our model's skin tone and the colors in his shirt. This image has a nice range of color for us to work with. Navigate to class files folder and open colorcast.jpg in Photoshop. In the next few exercises we'll apply our knowledge of RGB values, the color sampler tool, and the Info panel to identify a color cast. Notice how the values of the top right and top left areas of the Info Panel display the color values in both RGB and CMYK. Try moving your mouse over color regions without clicking. Notice that the white values all equal 255, the black values are all zero, and the gray values are equal. The info panel will also appear, displaying the RGB values of the pixel your color stopper has labeled #1. You will see a small target-like icon appear along with the number 1. Click and hold the eyedropper icon until a menu of options appears, then select the Color Sampler Tool.Ĭlick once in the white area. Locate the eyedropper tool in your tool bar. This tool is different from the Eyedropper tool, which allows you to click a point in the image to set foreground/background color. Used to see the RGB or CMYK values for a given point in image. Take a look at the difference between the two pictures: This helps draw the viewer's attention by creating distinct light and dark areas. Here are two examples of identifying the higlights, midtones, and shadows in a black and white image and in a picture in color:īy increasing the intensity of highlights and shadows, we can increase the contrast in a picture. The shadows are the darkest portions of an image, which are often almost black in color. The highlights are the brightest areas, and the most extreme highlight is white. However, we can use Photoshop to fix the lighting by manipulating the highlights, midtones and shadows. Sometimes an image may be underexposed when the photographer captured it in an envrionment without enough light and the opposite situation could lead to an overexposed picture. We can use this knowledge to evaluate a photo and determine which method will be best to correct it. The absence of all three colors in this color mode creates color black. This means that adding all the colors together at full strength on the screen creates white. The image we will be using today is in this color mode. Most digital cameras also take pictures in RGB. RGB is the standard color mode for any kind of display device including televisions, projectors, and computer monitors. CMYK values can be very useful to reference for skin tone balance, which we will work with in a later exercise. CMYK is the standard for all printing devices, but Photoshop can approximate its look on a display. The "Key" color in CMYK is always a pure black.ĬMYK is only used for printing and is a subtractive color mode, which means that the absence of all color creates white. CMYKĬMYK stands for the pigments Cyan Magenta Yellow Key. There are a handful of color modes in the graphic design world, but the two standard are CMYK and RGB. Introduction to Color Modesįirst, let's take a quick look at color modes. We will work with Curves and Levels Adjustments. In this exercise, we will take an outdoor portrait and correct the color in the image using several methods. An extra project will be available for students to learn how to add color to black and white photo on their own time. This class details the use of multiple layers and layer masks for advanced blending and non-destructive editing. Learn to edit photos with techniques for beauty enhancement. Use the Healing Tool group to remove blemishes, wrinkles and other unwanted distractions. We will cover advanced techniques used by industry professionals for portrait retouching.Įxplore RGB and CMYK color modes with exercises in color correction and skin tone balancing. We will concentrate on color correction, retouching, and beauty enhancements. In this class we will build on basic Photoshop skills, so it is important that you begin with a basic understanding of the program. Welcome to Photoshop 2: Portrait Retouching and Color Correction!
