does anyone have a good method for (oil) painting rocks which show through water such as are
found in streams? i want them to appear to be underwater yet visible.
Hi, I saw your question on Google so thought I would reply. I have a very popular exercise on my website regarding "Painting Rocks Underwater" in oils. It is a step-by-step exercise showing the methods of using oils transparently in a glazing manner to create the effects of water over the rocks and water movement. The rocks and pebbles are very visible as this is a clear stream exercise.
The following link will take you to the page of free online lessons in drawing and painting.

I hope this is helpful
Outside of the other method described (glazing), you can paint the underwater rocks directly. They look underwater because of the of the color shift from surrounding rocks that are peaking above the surface. And many times the shape of the edges can be a little wobbly to indicate the water movement. If you're on location, look through a little circle in your finger so you can isolate out the color difference from the above-surface rocks. If you're working with oils, you can also soften the edges of the underwater rocks as well.
I have a friend who does a lot of underwater rock type paintings you can check out.
