First open a picture, any picture, in Photoshop. I use an image of trees for this tutorial.
Now press Ctrl + Shift + U to desaturate the image. That will turn your image into black and white picture.
Next press Ctrl + J to duplicate current layer and on the new layer on top, press Ctrl + I to invert the image.
Put the current layer (the one on top) in Color Dodge blending mode. Now don't be scared if your composition turns to white, cause it will change in a second. This is how your layers should look like:
Go to Filters - Blur - Gaussian Blur and apply it. The amount of Blur will change according to your picture size. For the size I used in this tutorial that value is good. For your pictures, you may wanna play around with that value in order to achieve the best possible result.
After you hit OK, this is the end result… pretty cool, isn't it? You just turned a picture into a drawing with Adobe Photoshop in a matter of seconds.
