Just a quick question here people...
I was wondering if anyone knows if there is a filter you can use on camera to neutralize those awful colors from streetlights? I -think- the lights are High Pressure Sodium or something but either way they clearly don't fall under "tungsten" or "florescent". I have a couple of places that I like to shoot at night but because of the streetlights I get this horrendous "orange glow", especially in the sky and clouds. It's stuff I can fix in Photoshop, but in this case I'd rather get it right at the camera if possible.

I've tried search Google on this but didn't really find anything useful so any suggestions would be greatly appreciated!
Peace,
Jim

Might use an 18% grey card, and set a custom white balance. Might make it easier...

We must use Google different: Thread, Wikipedia, Another thread.

You probably won't be able to correct (fully), since the spectrum isn't continuous.

Not a hope. Low pressure sodium lights emit 95% of their light as yellow.

No amount of photoshop will fix that.

You could render it as black and white...

Actually I can and have fixed them in Photoshop without having to resort to b&w but it usually involves -a lot- of work...I was just looking an easier way.

Thanks one and all for the comments...I guess I'll keep doing it the "old fashion way" for now.

Peace,
Jim

I'm intrigued. Can you share a before and after with us?

Here's a link to one I recently posted in the Critique Forum...

I've done others as well but nothing that I have loaded to a hosting site at the moment...at least no "before" shots. Typically I only post my "finished" work for review so I almost never upload the before shots to my hosting sites. Either way while it's quite tedious work, in most cases it can be done.

Peace,
Jim
