These are amazingly similar to thin section under crossed polarizers... Who knew that rocks and beer had more in common than Geologists.. :)
Apparently that's not even polarized light.. They claim it's just one source of natural light from the side, and one from the top..
Interesting..
My immediate thoughts when looking at them were that they were either using polarization or DIC. I don't know how one would get the saturated colors without one of these techniques. Then again, I haven't tried it myself. Hmmm, might be an excuse for an experiment!
I actually have two neckties that have images like these on there...can't remember which two but they are similar to these here (but mine don't look so wild): Microscopic image neckties <-scroll down
To kirbic and to coryboehne. This is Lester Hutt, president of BevShots. You are correct about using crossed polarizers. I was interviewed by someone in UK's press about this, and I was accidentally misquoted and/or I didn't explain the process clearly enough. Sounds like you've shot these kinds of pictures before for geology... would love to hear from you.
