Tài liệu Photoshop cs5 by Dayley part 55

Chương 12: Điều chỉnh quy trình làm việc Điểm mấu chốt ở đây là bạn có thể sử dụng các điều chỉnh tự động cho một sửa chữa nhanh chóng mà thực sự có thể làm việc nếu bạn dành thời gian để tìm ra thiết lập là tốt nhất với mỗi hình ảnh cá nhân. Điều này có vẻ như làm việc quá nhiều cho một cái gì đó được cho là dễ dàng? Tôi cũng nghĩ vậy. Stick để điều chỉnh tùy chỉnh, bạn sẽ có ít hơn để nhớ, và hình ảnh của bạn sẽ nhìn tốt hơn. | Chapter 12 Adjustment Workflow The bottom line here is that you can use the Auto adjustments for a quick fix that might actually work if you take the time to figure out which setting is best with each individual image. Does this sound like too much work for something that was supposed to be easy I think so too. Stick to custom adjustments you ll have less to remember and your images will look better in the long run. Using the Adjustments Panel The Adjustments panel is your one-stop shop to quickly click an adjustment layer over your image. I ve already introduced you to the icon in the Layers panel that allows you to add a fill or adjustment layer the half-black half-white circle. The Adjustment panel is accessed with the same icon as shown in Figure 12.2.

Use the Photography workspace to quickly readjust your panels so that the Adjustment panel is in the main panel area above the Layers panel. If you are unsure how to do this review workspace presets in Chapter 2. Adjustment icons The upper portion of the Adjustment panel is dominated by the Adjustment icons. Although they are not labeled you will soon get the hang of which is which. To get started hover over and highlight each of them and watch the name appear in the Adjustment name area of the panel. These adjustments are found in the Adjustment panel Brightness Contrast This option gives you two basic sliders. The first adjusts the brightness of the image unilaterally enhancing or reducing the brightness of the pixels. The second adjusts the contrast changing the value of the midtones in the image by making the tones on the dark side 50 percent darker .
