Rock candy, FTW!
Setup is light behind the subject, in the form of a small softbox, with a bare speedlight hitting the candy head-on, to light up the stick a little bit.
To either side of the subject are black flags, to give the edges some definition.
200mm (320mm APS-C equivalent) at ISO 100, 1/250, and f/11. The light at the back is set at around half-power, the speedlight is set to 1/16.
The setup looks like this:
One of the advantages to this shooting style, where the background is completely blown out is recomposing in post is easy. Extend your canvas, fill it with white, and drop the shot where you want it. No extracting necessary.
I added the vignette in post, and it's the first step toward turning this shot into a retro candy advertisement.
