Cold. Woke up at 4:00-something, Sadie wanted to go outside, so I let her out. It's not as cold right now as it has been, but it's not the kind of thing I want to be hanging around wearing just a bathrobe in either.

Played with Darthcam some tonight. Originally it was going to be a comparison between the TRV-950 and Darth, but the TRV was having some issues. It ended up not really being necessary, as the differences were pretty obvious once we started looking.

(I was gonna post an example here, but it turns out that the LJ scrapbook won't show images beyond the 640 x 480 size, and I don't wanna deal with online storage right now.)

A DV camera shoots an image in 16:9 format that's 480 pixels high. That's the best standard-definition format, and this image is actually a little higher resolution than what a DV camera puts out (DV fakes it a bit with non-square pixels), but it's close enough for the comparison.

What Darthcam shoots is 1920 x 1080. Since I can't show you a full 1920 x 1080 pic, I have this one to compare:

The inset picture is the equivalent of the output from a 16:9 format DV camera. The bigger outside pic is what Darthcam shoots.
This pic doesn't do it justice. Here's a closeup from the original shot:

And no, that's not a blowup. That's from the original snapshot. The whole picture won't fit on your monitor unless you have an Apple Cinema display or something equivalent.

You can see how grainy the image is. Noisy might be a better word, since it's electronic encoder noise and not actual film grain, but you get the idea. You can see the detail in my irises (as well as the bags under my eyes-- sheesh) and individual hairs on the side of my head.

This gives me really good hope that I can actually use the footage for greenscreen work. I still need to really try it, because there are some other technical issues to deal with, but it's a very real possibility.

And that's just cool.
