Camera Rapid Response

Coworker: Gha… Do we have a high-megapixel camera that can focus on just the interference pattern on these two films while filtering out glare from overhead lights?
Me: Kind of, give me a few minutes *runs to car, gets camera, tripod, and polarizer, returns*
Coworker:  Where did you get that?
Me: My car.
Coworker: Do you drive around with that stuff hoping for weird cases where an excess of camera equipment will be useful?
Me: Maybe….Yes.

The photos came out well.  I make inconsistent deformations in thin-layer films with sub-wavelength spacing look good.
