Description
Pretty straightforward.
1. Get planes of face and shadow boundaries from photo
2. Create a new layer and fill it with med to light gray and begin to fill in the most basic lights and shadows
Protip: it's a good idea to keep the reference photo beside where you are working or on another screen if possible.
I don't recommend painting over the photo itself because that can get confusing!
3. Start to add in the different values found in the shadows (shadows are not just one tone!)
4. Here I am blending in all of the shadows and highlights. I usually turn the sketch off at this point, or have it at a very low opacity.
5. Airbrushed some shadows and highlights in an overlay layer, painted in some more details
6. All done! (I used Iris Blur to blur some of the portrait)
