Quarter II Computer Science Week 1 The Spot Healing Brush This tool’s cursor is a round brush, perfect for pimples or moles, fixing dust and specks in old photos, and removing anything that is roundish in shape. To use Spot Healing Brush, grab it from the Tools panel by pressing J (its icon looks like a Band-Aid with a circle behind it.) Then put your cursor over the blemish and adjust the cursor’s size so it’s slightly larger than the area you want to fix. The Options bar’s settings let you control exactly how the Spot Healing Brush works: Mode. Replace, Multiply, Screen, Darken, Lighten, Color, and Luminosity. Replace is handy if you’re using a soft- edged brush because it preserves some of the texture and details around the brush’s edges. However, Normal mode usually works just fine.  Type. This setting controls which pixels Photoshop looks at when it’s healing. You’ve got three options: - Proximity Match. This option tells Photoshop to use pixels just outside the edge of the cursor to fix the blemish. - Create Texture. Choose this option if the area you want to fix is surrounded by tons of details. Photoshop tries to recreate the texture by looking at the pixels inside the cursor. - Content-Aware Fill. This option is pure magic, and Photoshop comes from the factory set to use it. It’s great for removing objects from photos. You can either single-click or simply drag to remove the item and Photoshop fills in the area with surrounding pixels. Amazingly, the behind-the-scenes code can recreate complex structures like brick walls.  Sample All Layers. Turn on this option to have Photoshop sample pixel info from all layers instead of just the active one. This setting also lets you do the healing on another layer instead of on your original image. Just create a new layer above the photo layer and make sure the new layer is active; when you click to fix a spot, the fix happens on the new layer. Here’s how to use the Healing Brush: 1. Add a new layer above the one you want to fix. Click the “Create a new layer” button at the bottom of the Layers panel and name the new layer something like Healing. Make sure that it’s above the layer you’re fixing and that it’s active. 2. Choose the Healing Brush from the Tools panel. Press J to activate this brush, whose icon is a Band-Aid. 3. In the Options bar, set the Sample pop-up menu to Current & Below. This setting tells Photoshop, “Create a sample from the current layer and any other layers that lie below it, but make the fixes happen on the layer I’m currently on.” This process gives you a ton of flexibility: You can lower the layer’s opacity to lessen the strength of the fix, change the layer’s blend mode, or toss it in the trash if you decide you don’t like it. 4. Mouse over to your document and set a sample point by Option-clicking (Alt-clicking on a PC). Photoshop has no clue where the good skin is, so you have to tell it. Option-click (Alt-click) is an area of good skin that’s similar in texture to bad skin. Now you’re ready to start healing. 5. Click (or drag across) the area you want to fix. Mouse over to the problem area and click it or click and drag to paint it away. You’ll see tiny crosshairs marking the sample point as you drag and a preview of the sample area inside your cursor. If you’re fixing a small area, like the bags beneath the guy’s eyes. If you’re fixing a larger area, you may need to set a new sample point every few brushstrokes to match the tone and texture of what you’re fixing. The Patch Tool It works by fixing big areas like dark circles or bags beneath tired eyes. It’s also handy for removing piercings, tattoos, even entire objects. To use the Patch tool, grab it from the Tools panel (it is in the same toolset as the Healing and Spot Healing brushes), mouse over to your image, and then drag to draw an outline around the area you want to fix (marching ants appear when you let go of your mouse). Next, click anywhere inside the selected area and hold down your mouse button as you drag to reposition the selection outline so it’s over a good patch of skin. The main choice you need to make is what the Patch menu is set to: Normal. Photoshop is set to use this mode straight from the factory. In this mode, you see the following settings to the right of the Patch menu: - Source. It takes the texture from the good skin and tries to match it with the color and lighting of the area just outside your original selection. To produce convincing patches, leave this radio button turned on. - Destination. If you’d rather select the good skin first and then drag it atop the bad skin, turn on this radio button. - Transparent. Turn on this checkbox if you want to copy an area’s texture but not its content. For example, if you’re working on a photo of a brick wall, you could use this option to copy the texture of the bricks onto those that look newer, without duplicating the bricks in their entirety. - Use Pattern. To apply a pattern to the area you’ve selected with the Patch tool, click this button and then choose a pattern from the menu next to it. However, you’ll rarely use this option because, instead of merely making Photoshop copy and blend pixels from one area to another, it adds the pattern you picked from the pop-up menu to the selected area. That said, it’s useful if you’re trying to add texture to an area that doesn’t have any.  Content-Aware. The Patch tool sports a new Content-Aware option, which greatly improves its ability to remove objects in a realistic way by modifying the pixels inside the selected area. - Adaptation. This menu lets you determine how much blending Photoshop does inside the selected area and contains five options ranging from Very Strict to Very Loose. Set the menu to Very Strict for only a slight amount of blending or Very Loose for lots of blending. The other options—Strict, Medium, and Loose—fall somewhere in between. - Sample All Layers. This option makes Photoshop sample pixel info from all layers instead of just the currently active layer. This lets you use the Patch tool on an empty layer instead of a duplicate of your image layer, resulting in slightly smaller file size. First, draw an outline of the offending area freehand (left). Once you see marching ants, click inside the selection and drag it to a good patch of skin and then release your mouse button (right). Problem solved! The Patch tool can help you keep that piercing secret for a little while longer. And by doing the patching on a separate layer, the original image remains intact. Zapping Shines and Shadows Clone Stamp tool can get rid of shiny spots and unsightly shadows in a hurry. It works by copying pixels from one area of an image to another. This photo would be worth framing if the subjects weren’t so shiny. To fix it, grab the Clone Stamp tool and set your sample point as close to the shiny area as possible to match tone and texture (right). Be careful not to let the sample point (the crosshairs) go into the shiny area, or you’ll replicate the shine. No more shiny spots! The shadows on the subjects’ faces and necks have also been lightened. And by setting the Sample pop-up menu to All Layers, you haven’t harmed the original image. Toggle the visibility of the layers you just added off and on for a quick before-and-after comparison. Steps in Using the Clone Stamp Tool in Photoshop: 1. Select the Clone Stamp Tool from the toolbar on the left side of your screen. 2. Then set the brush size and hardness. 3. Put the cursor in the area where we want to duplicate the pixels. 4. Select the source area, Press the Alt key and move the cursor to the location where we want to take pixels from the source area. Click the mouse in that location. 5. Release the Alt key & move the mouse back to the original location. 6. Press the mouse button and paint the target location. Whitening Teeth You can begin by selecting the teeth—the Quick Selection tool works well. How to Whiten Teeth in Photoshop 1. Open an image and zoom in so you can see the subject’s teeth 2. Add a Hue/Saturation Adjustment layer. 3. Lower the Adjustment layer’s saturation and increase its lightness. 4. Fill the Hue/Saturation Adjustment layer’s mask with black. 5. Activate the Brush tool and choose a soft-edged brush set to paint with white. 6. Click and drag to paint across your subject’s teeth. 7. Save the document as a PSD file. End.
