Go to some of the images available on the computer—some
images come with PhotoShop— or import your own images from a disk Practice: 1. Creating a new file Handy Keyboard Shortcuts SHIFT + TAB: closes everything but toolbar; click to bring back. “D” defaults chip to B&W “X” key flips chip from foreground color to background color In Brush tool: Brackets near “P” key: left/right bracket will enlarge or reduce brush size Space Bar + Scroll on mouse: Enlarges or educes document size Must indicate you want to do this under Edit>Preferences>General: Zoom with scroll wheel (available in CS2 and CS3) Inside Mask Icon: To swap
figure/ground: ALT + Backspace = Defaults to white foreground Inside Mask icon: SHIFT + CTRL = on/off mask ALT + CLICK = brings up mask so could view it Copy a Layer: DRAG LAYER into ICON layer inside Layers Palette CTL +J= creates its own layer Layers: rearranging layers; linking layers; making layers visible and not visible by using the Show/Hide column in layers (eye icon); applying a gradient in a layer and how to make that gradient’s effect on another layer; changing opacity of layer (e.g., can allow other layers to show through when working with multiple layers); applying different blending modes to the layer (can affect how an image blends with layers below it—note that blending mode is to the left of your Opacity text box in Layers palette); naming a layer; adding text to a layer color swatches History Navigation Palette/menu when a tool is activated 6. Tools: Selecting, moving
marquee (rectangular, elliptical)
move
paint bucket
lasso, polygon lasso, magnetic lasso
magic wand
eraser gradient Note: selection tools include marquee tool, move tool, lasso tool, and magic wand 7. Selecting, creating, moving, filling, undoing with history, using layers palette, deleting 12. cropping (remember to press Enter when done and not select>deselect) 13. Using brushes 14. selecting and painting—selecting and adding
gradient 15. adjusting tonal range of photo (Image>Adjustments>Levels) 16. removing a color cast—imbalance of color (Layer>New Adjustment Layer>Color Balance) 17. Replacing colors in an image using Replace Color Command (creates a temporary mask –masks let you isolate an area of an image so changes affect just the selected area and not the rest of the image) How to: select background layer, select marquee and draw selection around area you want to replace color. Choose Image>Adjust>Replace Color. In dialog box, use eyedropper tool to select any color that’ll be masked and replaced with a new color (first eyedropper tool selects single color, eyedropper plus tool adds color to selection, eyedropper minus tool subtracts colors from a selection). Adjust tolerance level (fuzziness) of mask located in dialog box. Use slider for hue, saturation, and lightness. click OK to apply changes. 18.
Hue: color Saturation: purity or strength of color I Lightness: how much white or black is in color 19. Adjusting saturation with sponge tool—try out different options in the toolbar 20. Adjusting lightness with dodge tool--try out different options in toolbar 21. removing unwanted objects with the clone stamp tool—you can clone an area of an image you want to eliminate— example: can eliminate an object by painting over it with the clone stamp tool (our boat and water exercise) Center clone stamp tool over the area/image you want to copy Hold down ALT/OPT and click to sample or copy that part of the image/area Click or drag clone stamp tool over the area/image you want to paint over 22. Replacing part of an image: Select area you want replaced (can use magic wand) go to an image in another document and do a selection of it and then >Copy Go back to the document where you want that image replaced and select >Paste Into. With the appropriate layer selected, adjust opacity to make
it blend better if needed. 23. Using Image>Adjust 24. Applying Drop Shadows 1. Layer>Layer Style>Drop Shadow 2. Try out different blending modes 25. Colorizing a Black and White Photo: Open B&W photo go to Image>Mode and change from grayscale to RGB create a new layer for colorizing the B&W select image you want to change/add color with a selection tool (lasso, marquee, etc) till marching ants Select color Edit>Fill -- be sure foreground color is selected for color to fill Select>Deselect. For each item in a photo you colorize, be sure to create a new layer. 26. Adjusting/changing color: Image>Adjust>Hue and Saturation 27. Cleaning Up a Photo: Be sure you’re in proper layer (background layer is OK) select area you want to touch up (like a scratch on a photo) with a selection tool (like lasso, marquee) close till marching ants Filter>Noise>Dust and Scratches move radius till blurs Click OK Select>Deselect 28. Feathering (blurs/softens edges—can be defined in marquee and lasso tools in their tool palette) To define a feathered edge for an existing selection: Select>Feather and enter a value for Feather radius.
How to make a vignette using marquee tool, inverse, and feathering: Open document with photo that you want to make a vignette Select image using elliptical marquee till you see marching ants in marquee palette, change feather value (e.g., 25) Select>Inverse (marching ants now include outside border of image) Strike the delete key Select>Deselect 29. Inverse (to delete area outside selected image) Select image with marquee or lasso tool till marching ants Select>Inverse Marching ants will now include outside border of your selected image strike Delete key Select>Deselect 30. Making a soft edged product shot background (as seen in some ads): Open new document in RGB mode Choose a light foreground color that you want to appear in the center of your background Fill using paint bucket In layers palette, create a new layer—make sure this layer is on top of the other one In new layer, set foreground color to a darker shade of the color you used earlier (e.g., if you started with light green, then choose a dark green) Fill the layer using paint bucket select Rectangular Marquee and draw a rectangular selection in your new layer that you painted dark color (eg., dark green) about ½” to 1” inside the edges of the image (your image is an all dark color that you selected, such as a dark green) Select>Feather, enter 25 for value or 60 if you have a higher resolution (300 ppi), click OK (feathering will soften edges of your selection—you’ll see the edges of your selection rounded on the screen) Press Delete on MAC or BACKSPACE on PC to knock out a soft-edged hole in your top/darker layer Open the head shot of a person or other silhouetted image you want to place on this background. Select just the image and drag it on top of your original document to give a studio backdrop look to your head shot or silhouetted image. Add headline and/or body copy 31. Resizing your image: Edit>Transform>Scale Hold down Shift key and drag on handles to the size you want (to maintain proportion) Press Enter/Return 32. Reflection of Image (like the Ducky exercise) Open new document with transparent and RGB add color to background layer—can use a gradient if you like Open Ducky image drag a copy of Ducky into your document resize Ducky image (Edit>Transform>Scale; hold down Shift key while dragging handles to resize; Press Enter/Return) Delete the white space in the ducky image (ducky is its own layer—be sure you are in that layer): Can use Magic wand to select white space and press delete While in Ducky layer, click in Layers palette flyout for Duplicate Layer While in Duplicate Ducky layer: Edit>Transform>Flip Vertical Drag Ducky down below the original Ducky where their bottoms are almost touching Lower the opacity of the duplicate Ducky copy to about 40% (gives it a reflection look) Add text if desired 33. Making
Clouds In document, select area you want to make clouds (or if you want an entire document, of clouds, then do File>New) Select color for clouds till foreground color chip is color desired Filter>Render>Clouds OK To adjust color: Image>Adjust>Hue and Saturation 34. To add
sun/sun glare in clouds Filter>Render>Lens Flare Adjust brightness level In dialog box move flare where you want it Select lens type OK 35. Blending two images as one (an example of a way to do this) Open two files Drag one picture from a file and drop it into another file (select one picture for the background and put the other on top in Layers palette) Edit>Transform>Scale (hold shift key and drag picture to cover the background layer) Go to blending mode flyout in Layers palette. Select multiply 36. Adjusting color Image>Adjust>Hue and Saturation 37. About Flattening your image You can make a copy of your file with the layers flattened once you have edited all the layers in your image. Flattening a file merges your layers into a single background and reduces the file size. Flatten you image only when you are content with your design. You should save a copy of your file with all its layers in case you decide to make changes later. Layer>Flatten Image 38. Softening Edges of a Selection Two ways to smooth hard edges of a selection: Anti-aliasing: softens color transition between edge pixels and background pixels; no detail is lost. Good to use when cutting, copying and pasting selections to create composite images. Once a selection is made, you can’t add anti-aliasing. Select Marquee or lasso tools In tool options bar, check Anti Aliased Feathering: blurs edges by building a transition boundary between the selection and its surrounding pixels. Blurring can cause some loss of detail at edge of selection. Select Marquee or lasso tools. Enter a feather value in the tools options bar (value defines the width of the feathered edge and can range from 1-250 pixels) To define a feathered edge for an existing selection: Select>Feather. Enter value for Feather Radius and click OK. Boat Exercise: Practice/Review1. Crop Crop tool Drag around image Grab handles to shrink, enlarge, and rotate (to rotate, place cursor on corner handle till double curved arrow appears and then rotate) 2. Adjust tonal range (contrast/detail in image)
>image>adjust >levels Histogram: dark triangles are shadows, white triangles are highlights, gray ones are midtones/gamma Drag Left and Right sliders (dark triangles) inward Make sure preview is on You can also use Image>Adjust> Auto Contrast 3. Remove Color Cast (imbalances of color) Layer>New Adjustment Layer>Color Balance (good to use an adjustment layer in case you later want to make changes) Drag sliders (15, +8, 0) Midtones Make sure preview is on OK 4. Replace Colors Replace Color command creates temporary masks based on specific colors and replaces the colors. Masks let you isolate an area of an image so changes affect just the selected area and not the rest of the image Options let you adjust hue (color), saturation (purity of color) and lightness
