How to Make a Color Image Look Like a Sketch

Open a color image in Photoshop. To get the best sketch image, high contrast images are preferable. If it’s needed, you can adjust the image’s contrast (Image>Adjust>Brightness/Contrast)

sketch1.jpg

Desaturate the layer that contains the image. You can desaturate by clicking on Image>Adjust>Desaturate.

sketch2.jpg

Duplicate the desaturated layer. On the layer palette, you can duplicate the layer by right clicking on the previous layer and selecting the option of duplicating that layer.

Select and invert the duplicate desaturated layer. You can invert an image by clicking on Image>Adjust>Invert.

Notice that now, with the inverted layer selected, change the blending mode to “color dodge.”

Set the Gaussian blur to this layer. You can do that by clicking on Filter>Blur>Gaussian Blur. Then you can set the radius in between 4.0-9.0. Choose the one that creates a nice sketch effect.

Pattern/silhouette tutorial using a layer mask

Step 1: Open your image. Duplicate the background layer and rename it.

reading1.jpg

Step 2: Make sure your new layer (not the background) is highlighted and run menu option Image » Adjustments » Threshold… The default value in the Threshold dialog box is 128. For this image I made it 75, press OK when you have it where you want it.

Step 3: With the threshold layer highlighted, run menu option Filter » Stylize » Diffuse… Select Anisotropic mode and press OK.reading3.jpgStep 4:Run menu option Select » Color Range… Use the eyedropper to sample the black portion of the image, then run the Fuzziness slider in the Color Range dialog box up to 200. Press OK. The black portion of the image should now be surrounded by marching ants.Step 5: Run menu option Select » Save Selection… Give the selection a name and press OK. Now deselect. We’ll reload the selection later.

Step 6: Make a new layer on top of the others. Select the Paint Bucket tool. Set the tool to fill with a patern rather than a color and fill the new layer. I used one of Photoshop’s built-in patterns.

Step 7: Make another new layer on top of the others and fill it with white. Add a layer mask to this layer by pressing the Add Layer Mask button on the Layers palette.

Step 8: Run menu option Select » Load Selection… Choose the selection you saved earlier from the dropdown menu in the Load Selection dialog box and press OK.

Step 9: Run menu option Edit » Fill… Fill the selection with black (which should correspond to your current background color if the mask layer is highlighted). Though you’ve filled the selection with black, you won’t see black in the image. What you should see is the pattern fill from the layer below showing through where the selected mask was filled. Deselect.


Step 10: With the mask layer still highlighted, select the Brush tool and choose a large, hard-edged brush. (I used the size 19 brush.) Painting on the mask with white as the foreground color, paint over those parts of the image you might not need, assuming you see extra stuff that doesn’t need to be there.

Step 11: Select the Text tool, get a font you like and add some text.

Step 12: Run menu option Select » Load Selection… The correct entry will already be selected by default in the dialog box, so just press OK. The text should now be surrounded by marching ants.

Step 13: Turn off visibility of the text layer. The text will disappear but the marching ants will be left behind. (Deselecting right now would be bad.)

Step 14: Highlight the mask layer and make sure the mask portion of the layer is selected. Run menu option Edit » Fill… Fill the selection with black (which should correspond to your current background color if the mask layer is highlighted, just like the last time we did this). Once again the pattern fill should show through the mask, making the text look just like the rest of the image. Deselect.

Step 15: Done!

Andy Warhol pop art

Open your portrait image, hold down the Alt/Opt key, drag the original image layer to the “Create a new layer” icon, call the new layer “Cut Away,” and click OK.

andy1.jpg

Use selection tools such as the Magic Wand and Color Range to roughly select and delete the background pixels from the new layer.  I like the Lasso Tool and the Pen Tool as well.

andy2.jpgandy3.jpg

Add a new, color-filled layer directly below the working layer—making it a Bright color so you can better see the final result.

andy4.jpg

To make the high-contrast image, ensure the Cut Away layer is active and select Image > Adjustment > Threshold. Move the slider so that the image contains only enough shadow to show the picture’s essential shapes.

andy5.jpg

Roughly select each image area that you want to paint with a single color, and copy the selection into its own layer.

Name each new layer, set the blending mode to Multiply, and click OK.

Activate each item’s layer in the Layers palette in turn. For each one click the thumbnail so that only its non-transparent pixels are selected, and choose Edit > Fill. Even if the Fill dialog’s Use drop-down shows Color, select it again. This triggers the Color Picker. Select a strong color and click OK twice.

andy6.jpg

Once you have repeated steps 4 and 5 for each colored item, you have a completed silkscreen-style image. Save the file and make copies in which you use permutations of the same colors. Each colored area is in its own layer, so it is easy to select and recolor it with a Hue/Saturation adjustment layer. Finally, combine all the versions in one large image.

Antiquing Digital Images in Photoshop

Here is one of my favorite tutorials.  Making new photos old.  I’m going to use one of the photos I took last week at my pho photoshoot.

antique1.jpg

Choose the crop tool (c). Hold shift while you click and drag the crop tool to keep it square. Crop your picture a little bigger than you want it to be.

antique2.jpg

Then duplicate the layer by dragging it to the new layer icon.

Go to Filter > Blur > Gaussian Blur. You want to blur the picture enough that some of the detail goes away, but so that you can still see what it is.

Give the layer a mask by clicking the button at the bottom of the layers palette that looks like a circle in a rectangle.

Pick the gradient tool (g) and set it to radial.

Start at the point of the picture you want in focus and drag away from it. The further you drag, the more will be in focus.

antique5.jpg

Now a grain Duplicate the bottom layer and move this layer above the blurry layer.

Go to Filter > Noise > Add Noise. Add enough so that you can still make out the picture.
In the layers palette, change the blending mode from Normal to Soft Light.
antique61.jpg


Click the button at the bottom of the layers palette that looks like a circle half-white and half-black.

Select Hue/Saturation. When the dialog box comes up, check the Colorize check box in the bottom-right.

Change the hue to a yellow-reddish color and pull down the saturation.

When your image looks good to you, select ok.

antique8.jpg
Create a new layer.

Make a selection with the marquee tool that’s a bit smaller than your image.

Go into the quick mask mode.

Go to Filter > Blur > Gaussian Blur and raise the level until it’s very blurry.

antique9.jpg

Exit the quick mask mode.

There should be a roundish selection around the center of your image.

Go to Select > Inverse (ctrl+shift+i), and fill with black.

To do that, make sure your background color is black, then hit ctrl+delete.

Change the opacity of the layer until it looks good to you.
