Advance comment: How to make a photograph of a cocktail in which the
only source of illumination is the cocktail itself, which is *not*
naturally a light source. A few solutions come to mind. This one will
be explained after the comments begin, if no one figures it out. I
suspect some, if not all, in this group will figure it out before
then.....

Alex, who doesn't mind sharing tips.

No this was not an ad for Bombay.....


If you're referring to your SI shot then this posting should have been
pre-fixed: [SI] Food - etc.

I see stray bits of white light in there, so I assumed there was a tight
light beam above.

Making that "glow" can be accomplished with UV light and tonic water
(simulates Cherenkov radiation look - used in movies.)

Congratulations, Alan. I knew someone would sniff it out.


It's true. Alan is wicked smart.

It's true that I'm wicked smart, but it's also true I read about that
trick a few years ago in the "making of" of a movie. That's just memory
(which is a finicky thing...) and now reading up on it again, the
secret is quinine (an ingredient in tonic water) which reacts to UV by
glowing blue.

Apparently today's tonic water's do not contain the same amount of
quinine as original tonic waters which were part of a strategy to
prevent (moderate? treat?) malaria.
