Lesson 6 (Virtual web hosting) Use Filters, Opacity, and Blending Modes
Lesson 6 Use Filters, Opacity, and Blending Modes PHOTOSHOP 4-25 painted using traditional watercolors. Sharpen filters can appear to add definition to the entire image, or just the edges. Compare the different Sharpen filters applied in Figure 28. The Sharpen More filter increases the contrast of adjacent pixels and can focus a blurry image. Be careful not to overuse sharpening tools (or any filter), because you can create high-contrast lines or add graininess in color or brightness. Choosing Blending Modes A blending mode controls how pixels are made either darker or lighter based on underlying colors. Photoshop provides a variety of blending modes, listed in Table 1, to combine the color of the pixels in the current layer with those in layer(s) beneath it. You can see a list of blending modes by clicking the Add a layer style button on the Layers palette. Understanding Blending Mode Components You should consider the following underlying colors when planning a blending mode: base color, which is the original color of the image; blend color, which is the color you apply with a paint or edit tool; and resulting color, which is the color that is created as a result of applying the blend color. Softening Filter Effects Opacity can soften the line that the filter creates, but it doesn t affect the opacity of the entire layer. After a filter has been applied, you can modify the opacity and apply a blending mode using the Layers palette or the Fade dialog box. You can open the Fade dialog box by clicking Edit on the menu bar, then clicking the Fade command. QUICKTIP The Fade command appears only after a filter has been applied. When available, the command name includes the name of the applied filter. Balancing Colors As you adjust settings, such as hue and saturation, you might create unwanted imbalances in your image. You can adjust colors to correct or improve an image s appearance. For example, you can decrease a color by increasing the amount of its opposite color. You use the Color Balance dialog box to balance the color in an image. FIGURE 28 Sharpen filters Original image Sharpen filter applied Sharpen More filter applied excessively
