Here's a technique that I came up with. I used an hdr image and decreased the exposure to separate the light source(s) from the rest of the image and did a bit of distorting with warp transform. I've found that this is one of the best ways to achieve realistic looking reflections. I guess it's kinda cheating (not 100% PS) but it looks good.
For the sake of comparison, I whipped up an old tube and used an hdr map.
BTW, how exactly did you use that 'Select Edges' Plug-in and for what?
