SO DevDays

Taking photos at the event was very difficult. For human eyes, everything was fine, but for a camera’s lens, there was very little light. I didn’t use flash during the event; a common courtesy to both presenters and audience in an already low-light environment. It made me really wish that I had a 50mm f/1.4 lens like this one, though; too bad such wide aperture lenses are so expensive!

Light source differences between two subjects in one picture cause color problems.

The other environmental difficulty for photography was all of the different light source types. There were fluorescent lights in the main area (blueish), recessed incandescent bulbs (redish-orange), and the projector light (near 6500K, or like-sunlight). So, in the picture at right, for example, the main subject, Joel Spolsky, was standing under incandescent lights. This gives him a redish-tinge. When correcting Joel’s white shirt back to white, the slides in the background, having a neutral tint before correction, end up tending toward blue after.

Regardless, I’m happy with the photos I did get. Again, feel free to check them out. Here’s the link in case you didn’t catch it earlier!
