Illustration Effects on Photos
We will complete this tutorial in class as an introduction to many of Photoshop’s photo transforming tools.
- Find a high-resolution color photograph of a person, preferably showing most of the body and with a solid background.
- In the Edit menu, select Define Pattern. Name your pattern and click OK to preserve an original state of this image that we will use later.
- Press Ctrl-J (PC) or Cmd-J (Mac) to duplicate the Background layer. Rename it as Sketch.
- With the Sketch layer active, go to the Filter menu and find Stylize > Find Edges. This gives us a quick line drawing effect upon which we’ll continue to build the illustration.
- Turn off visibility of the Sketch layer by clicking on the eye icon on the left edge of the layer.
- Select the Eyedropper tool from the Tools panel. Click anywhere inside the original photo to set an existing color as the Foreground color. We will use it to fill the background behind our subject.
- Create a new layer. Fill it with your Foreground color: Alt-Delete (PC) or Option-Delete (Mac).
- Name the new layer Backdrop, and move it to just under the Sketch layer.
- With the Backdrop layer active, go to the Filter menu and select Filter Gallery. Twirl open the Texture section, and click on Texturizer,
- In the settings for Texturizer, set the texture to Canvas. Set scaling to 100%, relief to 3, and the Light source to Top. Adjust to your tastes. Click OK.
- Turn visibility of the Sketch layer back on, and make it active.
- Change the blend mode for the Sketch layer to Multiply. This will make the white parts invisible.
- Create a new layer named Painting and move it just under the Sketch layer. Set its blend mode to Hard Light.
- Zoom into your image a bit. Select the Pattern Stamp tool, which is located in the flyout menu for the Clone Stamp tool.
- In the Options bar, click the Pattern Picker to open the menu. Locate your original photo image and select it.
- At the left end of the Options bar, choose a small, soft-edged brush.
- Start painting on the Painting layer inside the image. It should be aligned because you’re in the same working document.
- Use the Eraser tool with a soft edge to remove excess color on your Painting layer.
- We’re going to fade the bottom edge of the painting: begin by adding a layer mask by clicking the Layer Mask icon at the bottom of the Layers panel.
- Press the D key and then the X key to set the foreground color to black.
- Select the Gradient tool in the Tools panel. In the Options bar, click the triangle to the right of the Gradient Editor Swatch and select Foreground to Transparent. Make sure the gradient is set to Linear.
- Starting in the bottom half of the image, click-and-drag the gradient upward a ways. Painting black on the layer mask thumbnail conceals content on that layer and reveals the layer below.
- Add another new layer, name it Gradient and move it to just under your Painting layer. Set the layer’s blend mode to Screen.
- The Foreground color should return to your prior color. With the gradient tool still active, go to the Options bar and choose the Radial Gradient setting.
- Beginning at the center of the illustration, click-and-drag the gradient outward.
- Save your work.
Colorize a Grayscale Photo
In days gone by, photos were black and white. In order to achieve a color photograph, professional tinters painted directly onto photo prints. Let’s transform a modern image into an old-fashioned, hand-tinted postcard.
- Find a high-resolution color photograph that would look interesting with a hand-tinted effect. Avoid photos with mostly black or mostly white areas (pure black and pure white areas will not pick up the color with this technique.) Vintage or romantic images are a classic for this effect, because it gives images an old-fashioned feel, but you can try other types of photos.
- Open the photo in Photoshop. Press Ctrl+J to make a duplicate layer of your photo (this protects your original photo from being ruined, in case you need it again.) Rename the duplicate layer as Grayscale. Save as a Photoshop file.
- If the photo is in color, go to Image > Adjustments > Black and White. Adjust the sliders until you like the result, and click OK.
- Set your foreground color for the first color you want to paint with. Keep in mind that you want to keep your color palette limited and that you don’t need to paint everything. Just key areas. You can “cheat” by using the eyedropper tool to select a color from the Background/color image.
- Create a new layer at the top of the layer stack and name it after your color or what area you plan to paint.
- Select the Brush tool from the Tools panel.
- In the Options bar, select a round brush with 0% Hardness.
- Move your brush out over the picture. You can adjust the size of the brush by using the [ key (smaller) or the ] key (larger). Paint on your image a bit, on the active top layer.
- Change the blend mode for the layer to Color, and adjust the Opacity percentage so that it is more subtle.
- Keep painting the same color on the same layer. Adjust your brush size as you go. To erase, press the E key to access the Eraser tool. Then press B to return to the Brush tool.
- If you want to adjust the hue, go to Image > Adjustments > Hue/Saturation and slide the Hue slider a bit. Click OK.
- Repeat the steps above for each new color: choose a new foreground color, create a new layer and name it, set its blend mode to Color and bring the Opacity down, and paint.
Each hue should have a separate layer, so that you can more easily adjust each if needed. Adjust the hardness and size of the brush as needed. Save your file frequently.
