Re: Nathan's PAD 27/12/2008: I bought a tripod!

Nathan,
An old trick for shooting fireworks would work here as well. When I wanted to accumulate bursts of fireworks on a frame I would take a black card and cover the lens (while it was kept open on bulb or timer settings) in between bursts. When the next burst had gone up and formed the way I wanted it I removed the card and added it to the exposure. I suspect something similar could be done by removing the card when you wanted to add light to one side of the circle or the other. For example, when I looked at your picture the left, or headlight side, was more dominant. Once you had accumulated enough streaks on that side you could keep the lens covered for the headlight side and uncover it for the taillight side. Many possible variations. And we haven't even gotten into HDR exposure combining yet. Keep up the good work.

Thanks for looking and the suggestions, Ted. I kept the exposure at 4 seconds because to go longer with the M8 I need to use the B setting, and for that in turn I need a cable release, which I did not bring with me, and which I could not find in any of the local shops. If I find one, I will try. The exposure here was f11 and 4 sec., so I should be able to go up to f22 and 15 sec. if I get hold of a cable release.
However, it will be very difficult to have light streaks all across the circle. The traffic patterns (as determined by the lights) are such that you only get significant traffic on one side of the circle only at any given moment. 

Cheers,
Nathan

*Subject:* Nathan's PAD 27/12/2008: I bought a tripod!
When I posted the view from my sister's apartment the other day, some people suggested that the image would be better if the cars were rendered as streaks of light. So on the first shopping day after Christmas I bought a cheap tripod (all of EUR10) and in the evening I set up the M8 on the tripod on my sister's window sill. I was not sure if the M8 was compatible with a tripod ;-) but it turned out it was. So I made several 4-second exposures, like this one: http://www.greatpix.eu/gallery/4253606_netUM#444023538_kbEBS-O-LB <<<< Hi Nathan, 
Interesting.
However may I suggest a 30 to 45 second exposure next time. Or longer? Wild guess really. But the M8 and ASA rating 160 and allow the camera to set the exposure time with lens stopped down to 11 -- 16 -- or 22. But let the camera do it's own thing first! The longer exposure would allow vehicle lights to fill many of the blank areas on the road and in the circle itself. Now I said maybe? When I've shot this type of scene, I'd shoot one at what the camera selected, then add 15 seconds in 15 sec increments for a dozen or so frames. And in some cases cut 15 seconds because you never knew what you had until the film was developed. Remember that's shooting film, so we bracketed considerably, "just in case!" J Most of the time nearly every frame "worked" to some degree. But with digital every frame can be checked as each exposure completes. In this type of scene, a blessing of digital! J But I'd also bracket even with an M8 because you still don't really see the best until it's big on the computer screen. J Imagine I had the audacity and the nerve to type that to a guy who produces smashing great mages like you do. J J Cheers, 
ted
