I work for Red Hat on the Fedora Linux distribution. Before that, I was a sysadmin in the Academic Computing group at Harvard School of Engineering and Applied Sciences. Photography is a hobby, and my main goal is simply documentation of my family life.

If you're a Pentax user, you may be interested in my definitive guide to Pentax hot shoe flashes and compatible 3rd-party options.

comment Color schemes and perception: If L*-linearity does not imply perceptual intensity linearity, then what is the best metric of perceptual intensity?
This question appears to be off-topic because it is about color for data visualisation in a way that seems unlikely to be useful to photographers.

comment Thinking of buying a canon 550D - few questions
Welcome to Stack Exchange! As this is a question and answer site rather than a traditional forum, please ask each question separately. (It's okay to post three right in a row if you have three questions.) But of course, please also search for existing Q&A first.

comment Is it possible to rotate an image by an arbitrary angle in Lightroom?
This is a helpful comment (for the case where leveling the horizon is the goal) but doesn't necessarily cover all cases where an arbitrary rotation might be desired.
