Long Exposure... Wheres the Horse?? c&c

[Tulsa]

Took this, this past weekend. Seems alittle noisy to me, what you think? Also, why is it looking darker now that I post here? Something Photobucket did? I have never had this problem, but I did just start using CS5 and a new computer...

It's cool, but I would have preferred to see it with a second curtain flash properly exposing the horse near the end of the frame (in whichever direction the horse was going)

Also just looked at you exif data. I see the ISO was on 640 - I remember reading a thread somewhere a while back where they were saying that on canon's the 1/3 stop ISO values (everything except 100, 200, 400, 800...) were always noisier than the full-stop values above them. I have been [unscientifically] experimenting with my 40d since I read that and it seems to be the case. Could be something to remember.

He is right. ISO 1250 on my t1i is more noisy than ISO 1600.

Would have been nice, but the horse was at the other end, and this was not a planned shot.

Thats good to know, I had no idea. Thanks.

curious why you would use such a high ISO in the first place for a long exposure? Couldn't you have used something like 200? or even 100? and add a couple seconds? I'm asking for my own personal reference, not that you did it wrong.

I think in the time I had to get ready for the carriage coming I just did not have time to go to ISO, I set the 25" and 20.

doesn't detract from the fact that it's a very cool shot!

I understand what you're saying but put yourself in his position, it would've been pretty hard to nail that with only one attempt!

Love the light pattern

Hence the point (and value) of this forum. After reading this thread, it's given me the idea of going out tonight and trying to catch some trail lights and use my flash to freeze a car, as sam suggested, and practice this situation.

so great shot as is, but sam's point helps add to the checklist of things to think about (and practice before) when in a situation like this. Thanks to all for the info!

Hmmm.. where do you see this article about ISO? wth?

 

[starcluster]

Yes! it does have some noise, and a little dark at the end, (building where the green light is located)..
but nice light movement : )

well done

I could have sworn that was a normal light, hmm, maybe it had a tiny green tint in the old glass. odd.

Thanks!

It's actually been discussed on several forums. Here is an example and a good explanation of the issue.
