Long Exposure with Rotating LED Colors
Jun 24, 2015 19:38:48 #
When shooting something at night, and the colors are changing faster than your shutter speed, what color would the final image be? Is there a particular color that is more dominant than another? Or should it just come out mixed or white? Thanks. -M

It depends on which colors are on during exposure. Red and blue will give you violet. Red and yellow will give you orange. If there is RGBY colors it will give you white. Hope this helps.

So, although that was quite a long exposure, if we blend all of those replies together, what color of language did you use when your computer crashed?
Could this be a record in time to reach 14 pages while still being as sensible and content rich as many threads?

Well I'm glad it came back, but please look at backups, losing all the time you put into making photographs can never be replaced. Time has no price....
or as was said many, many years ago in the IT industry:
"Jesus saves. So should you..."
Very good luck and get someone to watch your backup.

The sum of light may end up with plain white (from overexposure), or mixed colors if you keep your exposure lower. Go to an amusement park and experiment. Distance to subject, ambient light, shutter speed, and EV will all contribute to the result.

That would depend on the dominant color.

Ferris wheel? What are you doing? In my mind, likely unpredictable. Too many variables. You would just have to try it. Personally I have not tried much action night photography. But one can certainly get a number of odd effects. One I've gotten that looks weird to the mind, though perhaps not to the eye, is a timed exposure of traffic lights. And getting both Red & Green lights in one image at the same time (as the lights cycle though during your exposure). Might even if a fast enough cycle get all three, Green. Yellow, and Red.

Ferris Wheel turns out great. Try different times, you will get great results. Try zooming in or out during the exposure. Can't beat it.
