My father had photography as a hobby for most or all of my life, and I guess I got it from him.  I remember him using a Canon AE-1 when I was a youth – I only had a Kodak 110 Tele-Ektra at that point.  As an adult, I eventually got various Canon PowerShot point-and-shoot digital cameras, then got an Elan 7 film SLR.  In 2003, IEEE Spectrum used one of my photos.

In early 2004, I got a Nokia 3650 smartphone – one of the first in the US to have a camera.  I took it with me on a long bike ride up the coast that February, holding it at arm's length to take photos of myself with surrounding scenery.

Four months later, I received an email from someone I'd never heard of, who led a team I'd never heard of.  He had found my blog post, looked at more of my blog, and wanted to discuss where to bike while vacationing where I lived... and also his team's need for a photographer/techie to do occasional work, all over the world.

I joined the team a couple months later, right around the time I started working around space science.  For over a decade, I alternated between operating and using astronomical telescopes and cameras, and flying places to take photos.  In fairly short order, I picked up the first of a few Canon Digital Rebel DSLRs, and some EF lenses, mainly mid-range USM ones.

Flying around meant I took a lot of photos of airliners, and one of them made it into the UK aviation magazine Air International in 2007.  The DSLRs also came in handy for taking a lot of pictures of observatories doing their things, which led to a photo of the Keck Observatory's twin lasers making it into the French science magazine La Recherche in 2013, and a photo of the Keck and Subaru lasers wound up in the 3rd edition of the Encyclopedia of the Solar System in 2015.

I also upgraded to phones with gradually better cameras - a Palm Treo 650, an iPhone 3G, and so on.  I stopped flying around the world in late 2015, and although I still enjoy photography, these days I mostly use my phone to shoot photos and videos of scenery and my family.

Why I'm leaving Twitter.

I've stuck it out and continued participating on Twitter while Elon Musk has run it into the ground, made it progressively more inhospit...
