Kitty Poop
Many years ago (21 years, 9 months as of this post), I used some as-of-then only slightly out of date equipment to record a one week time lapse of the cats’ litter box.
I found the video on a CD-ROM (remember those?) and thought I’d see if it was still usable. It wasn’t – Quicktime had abandoned support for most of the 1990’s era codecs, and as it was pre-internet, there just wasn’t any support any more. I had to fire up my old Mac 9500, which booted just fine after years of sitting, even if most of the rubber feet on the peripherals had long since turned to goo. The OS9 version of QT let me resave as uncompressed, which of course was way too big for the massive dual 9GB drives in that machine. Youtube would eat the uncompressed format and this critical archival record is preserved for a little longer.

Visiting the Burj Khalifa
Dubai is an interesting contrast to Iraq. The first time I went through DXB from BSR it was more than a little culture shock. Getting out of the airport only amplifies the experience.
Jared and I had dinner at the Mall of Dubai and before eating had a little walk around the fountains – the largest dancing fountains in the world at the foot of the tallest man-made structure in the world.
Dubai is an good place to spot cars. Obviously the gold accented rolls is more pose-worthy than the $450k GTO. Then again they were probably posing with the license plate number which I think was 1, and therefore cost as much as 20 Ferrari GTOs.

On the Road in Iraq
We took a very nice tour from Baghdad to Basrah by car. The countryside is pretty amazing, from the relative lushness of the fertile crescent to the desert sands of the south to the marshes of the deep south and the distant flare gas fires on the horizon.

HDR video with SLRs
HDR is kind of cool – a nice way to get past the limitations of solid-state image sensors and recover some of the latitude of film, even improving on it.
The problem is that solid state image sensors tend to have very linear responses to light – an underexposed image vanishes into the noise floor of the sensor while an overexposed image clips off to pure white. Film exposure response is commonly called an “s-curve” and basically means there’s some data in the random conversion of a light sensitive molecule here or there even in the most underexposed image, and a few that resist converting under the harshest blast of light such that there is perceivable data in both.
This film is a pretty impressive example of HDR video. But there’s something a bit odd about such a technical achievement in cinematography mixing up “underexposed” and “overexposed.” The funny thing is, they’re using the terms as in making a print (e.g. printing on photo paper) or an x-ray where more light darkens the print: the paper starts out white and turns black with more light vs. a film or digital exposure where the media yields a black result that increases in representational lightness with with increasing light exposure.
