Yes Scott, I am aware that North American AC power is 60 Htz (I believe 50 is still standard in some overseas places). What I was questioning is whether the "strobing" was caused by the cycle or if it was something else inherent in the LEDs. Now that I think about it, it makes perfecxt sense that it is caused by tha AC cycling as being a diode it is probably only lighting on one half of the cycle and blocking the other half. I just didn't think about it last night, all I was thinking about it was how easy it was to see it when the lights were in motion or even by turning your head (so long as you don't fix your eyes on them). In addition to the Christmas lights outside my house I light most of the interior with LEDs also, as they are so much more efficient than incandescents and even compact fluorescents (not to mention they don't contain mercury like the CFLs do). Now that they're getting some good lumens per watt out of them the only disadvantage to them is the price, and even that is getting better.

Not sure what to tell you... it's certainly different.

Agreed. Both of these reshoots are really interesting, and fun to look at. Maybe they need a new reject button "High caliber work - these shots are too classy for RP"!

Or a new initial, "RNP" for ridiculous nit pick.

Why do you need to stand right next to the tracks?

No offense directed toward the OP, as these sorts of shots are commonplace, but can someone, such as one or both of those originating the two enthusiastic posts I quote, explain to me what in the world is so interesting about a wall of light, or three stripes of light, lined out across a non-descript night scene?

I don't intend to offend, I honestly have no clue what anyone sees in shots like this that represent interesting composition, interesting light, interesting contrast, etc. What do you see?

I refer specifically to the trackside night long exposure shot where the main light is the line of the passing headlight itself, not those taken from farther away where the main light in the scene is what the headlight illuminates. Why the stripes?

I appreciate that tastes vary, sometimes significantly, and it doesn't bother me that others have a taste for something for which I have none. It does bother me that it makes no sense. There are lots of other shots - tunnel glow night shots, for one - that I don't usually take much interest in but I can understand why others would. But the three strips especially - the shots at issue in this tread being the same concept with more than three lights - I just don't see it.

I do see value in the crossing gates dashed red quarter circles shot, and sometimes I see the value in the dashed red passing EOT device night shot, as some sort of indicator of passing, as opposed to a white stripe which makes me think first of a defective negative rather than of photographic content.

Merry Christmas everyone.
