Amazing photos, guys. Can either of you guys give me some hints? Like, how long did you do for both of them? You're stacking, right? Do either of you have an intervalometer? If 3 hours plus, how are you getting all the battery power? Also, like, favourite aperture, ISO, WB, would be cool to know. I'm rocking out on WB 4000.

1600 ISO, f3.5, 30 second exposures, at 10mm on a wide angle lens. Used a freeware thing called StarStax to stack them, and I like a tungsten white balance with some shadow + black tweaks to silhouette the barn better. Mine was ~350 exposures. Used a decomissioned iPhone 4 to drive a TriggerTrap mobile (these are really handy!) until the phone died, about 3.5 to 4 hours. Trust me on this: remove any filter you may have to prevent the lens-to-filter pocket from fogging up overnight, this happened to me in steamy Myanmar and in the cold nights of Northern Ontario, so I think it's going to be a commandment going forward. The camera battery pack was fine - 7D with two aftermarket batteries in a battery grip.

Ok, so this question is really dumb, and I'm pretty sure I know the answer, but I'm hoping someone could clarify this for me a bit. Do longer exposures, in any way reduce the amount of light in the shot? I'm watching a video of a guy taking a nighttime shot of some rocks with a small brick building in the background. He paints the rocks with this massive flashlight, nick named "The Sun" or something. The shot comes out looking pretty decent but I'm thinking if you're shining "the sun" at a rock it should show up as white on the camera. As a note, he shot at ISO100 for 18 minutes.

In short, yes. If you use a very small aperture at a low ISO, you'll need a whole bunch of light over a long period to get it to show up in the image. When you're talking about 18 minutes of time, a couple seconds of light from a flashlight is not going to be enough to overexpose anything. I can't think of a great way to explain it other than go buy a copy of Understanding Exposure, it should help you visualize what's going on a lot better.

Given: Situation A: ISO100, f/22, 18 minutes Situation B: ISO100, f/22, 30 seconds If you have a quantity of light X, will both situations register it as X or would A register it at (fake values I just made up) X and then B register it at .23*X. (So that 23% less light gets in) Less technical, if you took situations A and B, illuminated a large rock for 5s in each shot, would that rock look exactly the same in both shots?

Oh man, that's awesome, and I immediately bought a triggertrap. I've been thinking about buying an intervalometer anyway, so that's great. I'll check out starstax too, I've just been using that photoshop action. huhu posted:Given: Yes, if you're in a room with zero light sources. No in any other scenario. And no for the first scenario if you're shooting at F22, ISO100. This is a weird scenario. Really, if you have a camera, just give it a go. That's how you get a better understanding of long exposure photography. I guarantee you everyone in this thread had to take a bunch of lovely photos before they got anything good.

I think star trails are one of those things that seemed a lot more straightforward with a battery-free camera. I used a $5 shutter cable on my fed 2. The main problem I ran into was light pollution/clouds. You have to have a nice dark sky, ideally a night with a new moon. I'm going to try again next time I go camping somewhere remote and try to get some better shots.

 Tumblr I nearly got bogged down driving in the snow. Don't get up to the mountains very much, but turns out when snow hits and you're in the mountains just before dawn above the freezing line a 2 wheel drive city car is asking for trouble.

Some great photos, guys. When I get a new camera I'll have a go using some of your tips. This is probably going to get drowned in pages full of New Year's firework photos but it is worth taking a look at a new book: FULLMOON by Darren Almond. He takes 15 min exposures under full moon. The book has about 300+ photos. The book isn't cheap but is very handsome (and large). Check it out here: http://www.taschen.com/pages/en/catalogue/photography/all/03123/facts.darren_almond_fullmoon.htm (Click "see all images" to see sample pages/photos) Would be interested to get feedback here. Is it interesting/new/surprising?
