Transparent water drops are very appealing things to paint. With a bit of practice and careful planning you'll find they're not as impossible to paint as you might have thought.
The first thing to get decide is which direction the light is coming from in your painting as this will determine where the highlights and shadows in the drops will be.
Then apply the following 'rules':
- There'll be a shadow underneath and to the opposite side of the light direction (in this illustration the light is coming from the right, so the shadow is underneath and to the left). Or just underneath if the light source is directly above.
- There'll be a highlight on the top; not in the center but towards the side the light is coming from (right in this illustration). This is the light source reflected in the water drop.
- There is a shadow at the top of the water drop (this may not seem logical, but it's caused by the refraction of light through the droplet from the shaded surface below).
- There is a highlight at the bottom of the water drop (again this may not seem logical, but it's also caused by the refraction of the light through the drop, this time from the light source).
