Retroreflectors are used in optics to send a beam of light back from whence it came. While this can sometimes involve laborious alignment of adjustable mirrors, these custom-built “zero degrees of freedom” mounts hold the high-reflector mirrors against perfect-90º prisms to guarantee the correct geometry.

2024 National Invitational Rowing Championship
As the semester finished, I traveled to support Trinity Rowing at the National Invitational Rowing Championship in Worcester, Massachusetts.
Unlike most other spectators, stationed down at the finish line, some coincidence and some bushwhacking led me to a position near the starting line. The benefit to this view was capturing the boats while they were still closely spaced, making for some really dramatic competitive compositions.

“No Filter”/Obligatory Eclipse Image
And of course, I had to take a picture of the eclipse. I stepped out from lab with my camera but didn’t have a filter. Instead, I took narrowed down the aperture and aimed to get some rainbow effects that might spice up the image.

Black Silvia
This black Nissan Silvia was a sinister presence at #GRIDLIFE last year, but the reflections from its surfaces killed the dark-and-menancing tone. I’d typically address this with a polarizer, but didn’t have one handy. Luckily, some polarized sunglasses did the trick. I rather like the effect of the bokeh’ed-out lens in front of the car, like a bodyguard waving away paparazzi.
