With the photo newly opened in Photoshop, we see in the Layers panel that the image is sitting on the Background layer: Step 1: Duplicate The Background Layer
Go up to the Layer menu in the Menu Bar along the top of the screen, choose New,choose Layer via Copy. Or, for a faster way to run the same command, press Ctrl+J (Win) on your keyboard:
Go up to the Image menu at the top of the screen, choose Adjustments, then chooseDesaturate:Step 2: Desaturate The Image
The controls and options for the Hue/Saturation adjustment layer appear in theProperties panel. To remove the color from the image, simply drag theSaturationslider all the way to the left to a value of-100:
This removes all color from the photo, leaving it in black and white
Next, we need to make a copy of our desaturated image. Go back up to the Layer menu,choose New, then choose Layer via Copy, or press Ctrl+J (Win) on your keyboard, just as we did in Step 1. Photoshop makes a copy of Layer 1, namesit Layer 1 copy, and places it directly above Layer 1 in the Layers panel:Step 3: Duplicate The Layer
In the upper left of the Layers panel, change theblend modeof the Background copy layer from Normal (the default blend mode) toColor Dodge:Step 4: Change The Blend Mode To Color Dodge
This inverts the image, giving it a film negative appearance:
Next, we need to invert the layer. Go up to theImagemenu at the top of the screen, chooseAdjustments, then chooseInvert. Or, pressCtrl+I(Win) on your keyboard for the shortcut:Step 5: Invert The Image
The document will temporarily appear filled with white. Depending on your image, there may besome areas of black here and there, but for the most part it will be filled with white:
After changing the blend mode to ColorDodge, the document appears white.
This next step is where we actually create the sketch effect. Go up to the Filter menu at the top of the screen, choose Blur, then choose Gaussian Blur:Step 6: Apply The Gaussian Blur Filter
Click OK when you're done to accept your setting and close out of the Gaussian Blur dialog box.
Now add a levals Adjustment layer by going to (image > Adjustment> levels).Step 8
And Were Done!
