These are the only fireworks I saw this year, on the eve of our independence day. M'lady and I were all set up to camp out here, chillin' and grillin' hot dogs, when the lightning and wind came over Steens mountain with little warning. We packed up the Subaru in a hurry, as I kept setting off 30-second exposures, just missing each burst of lightning between them. The second I got this exposure, we raced off the playa at 60mph, as the storm rolled in behind us.
POSTSCRIPT LOLOL: Please ignore all the good things I said about the D7100 in response to commenters' queries, here and on other sites. It is, in fact, NOT like the D7000/600/800 - it apparently has a Toshiba sensor rather than an oh-so-sexy Sony one, and it bands real bad in low-light shadow-push situations. It's not as bad as a 5D2, but it's certainly not as impressive as its predecessor. AS SUCH, this is the last image my D7100 will have taken under my purview, since I've already picked up a D7000 to replace it. I'll take better dynamic range over the extra detail possible in ideally-lit ISO 100 exposures - especially at half the price.
EDITOLOL: Regarding some comments I've received: I'm not saying the D7100 is bad - I've made some of my best images on it. I'm saying it's disappointing that it costs twice as much as its predecessor currently does, but it's far worse in low-light and super-wide-dynamic-range situations. It's just not the same type of performance I'd expect from an ostensibly high-end modern Nikon sensor. My thoughts come from experience with many different bodies, not from reading DxO charts or reading articles. Either save the money and go with the 7000, or man up and go with the 600. Both will probably serve you better if you shoot in dramatic light.
