Một trong những lựa chọn này đặt ra một thương mại-off. Trong việc tạo ra nhiều hơn một hình ảnh, bạn hy sinh thời gian có giá trị lặp đi lặp lại quá trình sửa chữa trên các phiên bản khác nhau của một hình ảnh. Nó thường tự chuốc lấy thất bại để làm việc trên hai hình ảnh để tạo ra kết quả tương tự | can you have too much resolution 11 Either of these choices poses a trade-off. In creating more than one image you sacrifice valuable time in repeating processes for correction on different versions of an image. It is often self-defeating to work on two images to produce the same results even using a detailed script because the difference in size and volume of information in the image will produce different results with the same application of tools. In creating one image and resizing you have to allow either interpolation of new image information or decimation neither of which may be the optimal process. You can t work on small images and resize up because detail will not be present. The best way to go about working with multipurpose images is usually to work with them at the highest resolution and then resize them smaller. Working at the higher of two or more resolutions retains the details for the higher-resolution presentations and decimates detail that will not be reproducible at lower resolutions. Softening or other ill effects from severe resizing can be countered somewhat by sharpening. See Un Sharpening and Boosting Contrast in Chapter 5 for more information on sharpening. A similar concept in retaining detail holds true when considering color depth. You will want to work in larger color spaces and at greater color depth to retain image detail and then reduce color detail and move to smaller color spaces after making corrections to reduce loss. You will most often use images from your digital camera at full resolution in RGB during corrections before reducing color and resolution for specific purposes. Can You Have Too Much Resolution There are two answers to the question of whether or not you can have too much resolution yes and no. The answer depends on whether there are other circumstances that make high-resolution images a waste because the information won t ever be used. There does come a point where the amount of image information is simply too much
