The lunar eclipse was just an excuse to haul out my binoculars…

September 27, 2015 | Astronomy, Optics, Telescopes | By: Mark VandeWettering

Tonight was a total lunar eclipse… Lunar eclipses are pretty, but not super rare. Tonight’s started before moonrise, and by the time I got out to snap a picture or two, totality was already over. More interesting perhaps than the eclipse was the optical gadget that I pulled out to have a look. Over the […]

Got a first generation (obsolete!) Lytro Camera…

April 24, 2015 | My Photos, Optics | By: Mark VandeWettering

I spent a couple years of my life working on a light field motion picture camera (and got named on two patents) as part of my former work, so I’ve been interested in light field photography and computational photography more generally. The company Lytro was basically the first to market such a device, and recently […]

Here are two more photos I took at last night’s camera workshop. I wanted to take something slightly more beautiful than a selfie, so I chose the Luxo statue outside the Steve Jobs building at Pixar, and some white flowers from the garden. Both were taken rather late in the day, under partly cloudy skies […]

An Experimental 4×5 Camera with a ridiculous lens… and a ridiculous selfie

July 2, 2014 | Optics, Photography | By: Mark VandeWettering

Over the years that I’ve been interested in computer graphics and telescopes, I’ve managed to pick up a bit of knowledge about optics in general, and specifically about camera lens design. In the past, I’ve been particularly interested in old cameras and photography, and in a kind of photographic minimalism. But it has remained mostly […]

On early camera lenses…

I like it when my life’s experience and interests toss me an opportunity, and out of the blue last week I received an invitation to help with a class a colleague is trying to put together to help people build their own cameras, and he wondered if I could give an hour or so introduction […]
