In this how to video, you will learn how to turn a photo into a line drawing in Photoshop. First, open your image in Photoshop. Create three layers of the same photo. The top two layers will be worked with. The bottom layer will remain the same. Take the top layer and change it to color dodge. Select control and I on the keyboard to invert it. Go to filter and blur to choose Gaussian blur. If you have dark lines, use a small amount of blur. You can use a lot of blur to get a unique look. Click okay to apply the filter. Once that is done, go to fill adjustment layer and desaturate the image. Once that is done, your drawing conversion is complete.
