1. Open a photo of a character in Photoshop, which is best for face outlines. 2. Press the shortcut key "Ctrl Shift U" to convert it into black and white colors. 3. Replicate the layer to get a copy layer. Press the shortcut key "Ctrl I" to convert the copy layer into a negative image. 4. Select the superposition of the copy layer to "color reduction". At this time, the picture will be almost unable to see, don't worry. 5. Select "Filter" menu to select "Fuzzy → Gaussian Value", the fuzzy radius value can be set according to the sketch lines you need. This is done for this descent image. Tip: If you don't feel very satisfied, you still want to be better, you can use shortcut keys "Ctrl M" or "CTRL L" to adjust, you can also use a brush, Beesier Pen, etc. Some modifications.
