for Joan R's @joansmor lighting group http://365project.org/discuss/general/29122/light-amateur . This is lit from the side with a single light aimed towards the backdrop. I spent a LOT of time trying to get the highlight off the front; final got it down to a tiny slit ... and didn't notice that the lines didn't quite line up. I wonder what would have happened with the reflection onto the left side of the glass had I moved the glass a bit further back from the background.
@skstein@grammyn This is (I learned) what water in a glass does to a background. There is a sheet of white and a sheet of black posterboard in back, then a lass of water in front. Yep. That's what you see in the glass. Might be called refraction.
