Digital image sensors are for the most part analog integrated circuits. Traditionally, analog ICs, and analog circuits in general, have been an area where a few highly-talented engineers made the breakthroughs and basked in the acclaim from their fellow engineers, if not necessarily becoming rich in the process. Everybody who knows a lot about hi-fi knows… [Read More]

Not too much celebrating
I ended yesterday’s post on celebrating the process by wondering if I should really kick over the traces and go with a white background and lens/sun artifacts like this: Cooler heads have prevailed, and I’m liking this better: The process of selecting the right set of images for this picture was time consuming.

Many watercolorists leave the edges of their paintings ragged, putting down color where the scene demands it, but feeling no compunction to fill the entire rectangle with paint. Both elevate the work… [Read More]

For some, that’s enough. If you’re one of those, move along; nothing to see here. Still around? I’m a numbers guy,… [Read More]
Still more infrared panos
Here are some panos I’ve done with the IR-modified a7 and the 28mm f/1.4 Nikkor-D. I’m getting a little looser with my framing. I ‘ve been playing with combining handheld HDR with stitching. AutoPano Giga will do the exposure blending and the stitching at the same time. It works well if there’s no wind. The… [Read More]
