Bokeh

What makes this case so interesting is that later scrutiny revealed nothing exotic at all.

The key to understanding what viewers were seeing lies in the physics of nighttime photography, specifically a phenomenon called bokeh.

Bokeh describes the aesthetic quality of blur produced when parts of an image fall out of focus.

It can be influenced by the lens aperture shape, which is often triangular or hexagonal.

Most consumer cameras use circular apertures, but many military night vision devices employ square or rectangular openings to maximize light intake.

Well, it does that with software.

Yeah, it's called Bokeh.

B-O-K-E-H is the photography term.

But it's being done digitally.
