Glass Anyone?

You need to paint say a wine glass, bottle, vase or window, and you ask yourself, "what's to paint?" How can I paint something that I'm looking THROUGH. It's not opaque or even translucent for krist sake...it's transparent...there's NOTHING to paint! Wrong, silica breath!
There are essentially two things you need to know to paint glass. 1.You paint what you see BEHIND the glass, whether it's up close or far away. 2.You paint whatever the glass is REFLECTING. So with the wine glass, I simply painted what was behind it (the potted plant) and reflected high lights off the rim, sides, stem, and foot.. Note that some of these reflections follow the shape of the wine glass, and thus significantly help to define it as such. Same thing with the wine bottle... I painted the bluish green of the glass itself (it's local color), what was behind the front of the glass (that inside dome thingy), reflected high lights and the dark backside of the wine label ( again,painting what's behind the glass). This was all done with super thick paint (impasto), but because the local and reflective colors are all in the right spots, correctly shaped, and value contrasted accurately, they read as a wine bottle.
Finally, take a look how this pair of glasses on this devilishly handsome gentleman were painted. Remember, paint what is BEHIND glass and any reflections off the glass. The only thing that says glass here is the frame and all I had to do was paint the skin tones behind each lense! Who is this bearded fellow?... 1. Brad Pitt? 2. David Lobenberg? 3.Moses?

DON'T THINK GLASS! THINK WHAT IS BE BEHIND THE GLASS AND REFLECTIONS OFF THE GLASS.

Oh, one more thing: PEOPLE THAT LIVE IN GLASS HOUSES SHOULD NOT THROW STONES.

And one more, one more thing: ALWAYS TRY TO KILL TWO STONES WITH ONE BIRD.

End of lesson.
