C O M T H E D I G I T A L E Y E enables you to combine the enhanced de- tail of the highlight, mid-tone, and shad- ow areas into one optimal image. Scanning at higher resolutions helps pre- serve detail. Scan the image at 300 pixels per inch (PPI) or higher on a atbed scan- ner. If the image is especially small, in- crease the scale and the resolution. Avoid exceeding the scanner's optical resolution if possible. For example, if the scanner's optical resolution is 1,200 DPI, you can scan it at 300 DPI and 400% size. ere is no advantage to scanning a black- and-white photograph in RGB mode. at will only produce an image with a larger le size. In most cases it will require desat- uration to eliminate discoloration. If there are stains on the image, scanning it in RGB can exaggerate them. For best results, scan the photo as a 16- bit grayscale to maximize the tonal range. After repairing it, convert it to an 8-bit grayscale before printing. If you later de- cide to add color or a sepia tint to the im- age, you can convert it to RGB mode and colorize it using one of the colorization features. CLONING Areas that are missing, scratched, spot- ted, or stained can be replaced with the Clone Stamp, Spot Healing brush, or the Healing brush. ese tools are specically designed to replace pixels in smaller areas. e Clone Stamp simply copies pixels from a sampled area and paints them to a target area with a brush. It's advisable to rst make a rough selection around the area to be repaired so as to avoid ap- plying the clone to areas that need to be preserved. In Photoshop, sample the area to be cap- tured by pressing the Opt (Mac) or Alt (Win) key and click the mouse to store the sampled point into the tool's memory. (In Corel Photo-PAINT, right click). Choose a soft brush and paint the areas that you want to correct. As you are painting, the cross indicates where the content is be- ing sampled and the circle indicates the area where it is applied. By default, these Figure 4 (above). As you paint with the Clone Stamp, the cross indicates where the content is being sampled from and the circle indicates the point where it is applied. Figure 5 (right). Photoshop has an extra feature called the Clone Source panel accessed from the Window menu that controls numerous characteristics of the tool including the size, angle, and offset among others.
