Sociotard Posted September 7, 2012 Report Share Posted September 7, 2012 Re: "Neat" Pictures Very strange diffraction pattern on the streetlights. Hmm, what do you find odd about them? Photography blather spoilered The diffraction effects Cancer posted about are the rays coming off the lights. They happen when the aperture (the hole that lets light into the camera) is kept very tiny. Keeping the aperture tiny is a good technique for catching lightning, since they let you leave the aperture open for a good long while, perhaps even several seconds. So you just put the camera on a tripod and have the camera continuosly take pictures. Then you have good odds that any given shot will have lightning in it. Besides, lightning is so bright, even a tight aperture lets in plenty of light The other possible trick (not shown, I think) is to rig a "slave" to trigger the shutter on the camera. A slave is normally a triggering mechanism for a flash. A slave 'sees' a flash go off somewhere else and triggers whatever flash it's attached to, so normally it's a good way to coordinate multiple flashes. Anyway, the diffraction looks similar to other ones I've seen. What stands out to you? Quote Link to comment Share on other sites More sharing options...
Cancer Posted September 7, 2012 Report Share Posted September 7, 2012 Re: "Neat" Pictures Nothing to see here (unless you want to sink into optics), move along. There's a large number of diffraction spikes, and they aren't equal in magnitude. They look to be bilaterally symmetric, but not azimuthally symmetric. I don't have the Fourier transform in my head to figure out what the shape of the blockage in the aperture plane is, which is unusual.

Michael Hopcroft Posted September 8, 2012 Report Share Posted September 8, 2012 Re: "Neat" Pictures The same reason Texas is generally thought of as being a desert. Then again, at least half the area of Oregon is pretty much desert. Hence the neverending controversy about who gets how much of the diminishing water supply in the basin of the Klamath River in the eastern part of the state. People there are used to using it to irrigate fields in land that would be useless for agriculture otherwise, never mind the effect on fish and wildlife (to which many of the farmers are openly hostile).

I daresay we are all guilty of that sort of thing to some extent. Quote Link to comment Share on other sites More sharing options...

Sometimes it's hard to remember some states are more than one environmental zone. Agreed. Texas is quite arid in its western regions, very much "plains state" in its central region, and heavily forested in its eastern region. At least three different biomes.

Captain Obvious Posted September 8, 2012 Report Share Posted September 8, 2012 Re: "Neat" Pictures I looked up the 100 biggest US cities in 1880, and it's not there at all. Can't be gold rush. Probably has a lot to do with military bases there. Quote Link to comment Share on other sites More sharing options...
