I was biking home when I saw the aftermath of a car accident which had left a small car standing perfectly on its side. I happened to have my brand new Canon 50D digital SLR in my bag and decided to grab a quick night shot to test out exactly how vastly improved the low-light high-ISO performance is compared with my antiquated 300D. The visual quality is not fantastic, with a fair amount of noise and much loss of fine detail due to noise reduction, but keep in mind that these photos were taken at ISO 12,800. Even at such an extreme ISO, the noise levels are approximately the same as what my old camera got at ISO 1600, and with far, far higher resolution, more accurate auto-focus, faster performance, etc.
So, I thought I would just get an amusing photo of the car on its side (note: the occupants didn’t look to be badly hurt, so it’s ok to laugh) but then it got a lot more amusing when the police pushed the car over back onto its wheels, and one got in and drove it away.
[Update 2: Here is an example of a super high ISO file with no noise reduction. Not very usable.]
