I have a guy driving 2 hours to "take a look at" my Tokina 11-16. I'm pretty sure he's going to buy it. He better not try to haggle!

Seriously, if he's driving two hours then he's obviously interested. As long as you described it thoroughly then really if he tries to haggle and gives you poo poo because he drove two hours then all you need to say is "hey look, you knew the price I listed at.

Doing it with a sound activated flash and a small aperture and long exposure sounds like it might create a better result.

I think you'll still be going on luck given how fast a bullet comes out of a barrel. The latency of the flash trigger, flash and camera added together may be too long. One way you can tip the odds in your favour is using a slower cartridge like .45ACP, .22LR or black powder. When I'm at the range and the light is just right(bright sunlight on the bullet against a shadowed background), I can actually see .45ACP bullets flying out of the barrel.

You can buy electronic timers you can use to delay sending a signal when the trigger is pulled.. giving thousandths of a second accuracy you can adjust with a dial. So assuming that the bullet has no variance in how long it takes to ignite, you can adjust the delay until you get it right. Mythbusters has done it several times for various projects, I'm sure it's a common application but Mythbusters is probably the most widely documented.

Last time I heard about this someone was using a laser trigger along with some insane high-speed flash he built himself (!) to do freeze frames of bullets piercing things, it was pretty cool. Anyone know who that was?

I built this trigger a little while ago http://hiviz.com/kits/mt.htm and tried some gun stuff with it in bright sunlight. I put my camera downrange and to the side, then used the sound trigger, spliced to a Yongnuo trigger. My camera fired via a Yongnuo receiver. It looks like the delay from sound --> trigger --> receiver --> fire camera was too great to catch any bullet hits (we shot .223 out an AR and a .40 handgun), but I still caught some cool stuff. Now that I have a .22lr I want to go and do some more, maybe with subsonic ammo, and with a better way of triggering the camera.

I think the easiest thing to do to catch a bullet coming out of the barrel would be to hold down the shutter on a burst, shoot the gun in the middle of the burst and hope you catch lightning. They have timers that detect gunfire for timing shooting competitions, but again, we're talking a whole new level of speed if you're trying to get a just-fired bullet versus a bullet hitting a target a distance away.

This is assuming a muzzle velocity of 1000m/s. His rimfire is probably half that and subsonic ammo would help even more, but with the shutter delay it would still be best to use the dark room + flash trigger method. Cool picture though.

TheLastManStanding posted:If you have a camera that shoots 10fps, the difference in bullet position between frames is around 100m (~300 feet). If your shutter speed is 1/1000, the bullet will appear faint and roughly 3 feet long. This is why a flash is used since you can have flash durations that are much shorter than 1/8000. No, my idea was to put the camera on burst and shooting in the middle of the burst in hopes that you catch the bullet just as it's leaving the barrel through sheer luck and coincidence.

High-speed film cameras used to capture bullets impacting things go through tens of thousands of frames in one second. They use motors that could run a lawnmower to spin the film reels.

So how does everyone handle their gear in public? I went to a local pub quiz tonight and some guy was there taking photos for something. He left a Canon 70-200 2.8 IS I in the corner with his bag of gear and then wandered around the bar taking pictures. Is this normal? He had a friend helping him but neither of them seemed to be paying particularly close attention to his stuff. I was sitting there shooting random photos with my 7D in the table right next to the corner so maybe he figured I'd watch it for him. I don't know, is this normal and I'm just over-protective of my stuff? I keep my poo poo on or around me at all times. If I was leaving it somewhere to take pictures of the bar I'd probably leave it behind the bar or at least leave my $1500 lens in the bag and not right out in the open. I don't know, Maybe I'm paranoid, but I thought it was weird. I wouldn't leave my 50 1.8 just sitting around in public like that.

I don't know, is this normal and I'm just over-protective of my stuff? I keep my poo poo on or around me at all times. At Quakecon, I saw someone leave a 5d2 with a 16-35 II on it for HOURS on the end of a table row. I think just because it was kind of near the NOC they thought it would be safe. Personally, I put my camera bag somewhere "safe" like in the DJ Booth (just ask any DJ, they function as coat checks!) or behind the bar or something while I have my camera on me. If that's not an option, I bring a satchel that will hold my 70-200 or 2 other lenses and just wear that. I would never leave my camera bag on a bar seat or something completely unattended. I often have friends who will watch my bag for me, as they're aware of how expensive camera stuff can be. So yes, that guy is crazy. Even if he knew the bar really well and a lot of the patrons, 30 seconds of going to the bathroom and that lens could be gone forever and no one would notice.

I carry a D3s when I'm travelling. If I'm not carrying the bag, the bag is between my feet. It is under my arm. It is under my head. If I'm sleeping, I'm hugging it. I don't show people it. If someone sees it, I am extra vigilant. Mind you, I'm not sure if I have trust. That poo poo is just rust with a t.

Blowing things up in your back yard isn't really a crime. More of an American pass time. I'm going to use my TFR powers to venture a guess that it was one of those little propane tanks. Like the ones you hook up to a coleman camping stove. The problem is you need an ignition source, if not all the gas just escapes in that white plume and disperses, most people will stick a road flare near by to solve this issue. I've done it a couple times myself with the bigger tanks. I've never gotten a decent photo though. I've always been too busy giggling like a school girl. Here's a pretty decent example. You don't need a .50BMG like those guys, just a decent velocity rifle round like a .308 or a .223.

Yeah, sorry. Just because english is my first language doesn't mean I'm any good at it. Mounting a candle near the object you're shooting is a great way to ignite whatever gas you're putting into the air.  You can also make some glorious fireballs throwing flour on a campfire.

If any of you Bay Area Dorkroomers want to come out of your parents' basements on Saturday night (11/20) I have some work in an art show in SOMA. http://www.wix.com/purposebeyondreach/inksoftruth There are several good photographers as well as a bunch of painters and also some live music. It's at Rancho Parnassus at 6th and Minna from 4-10:30. The show is a benefit for a local food bank, so the cover is 5 cans of food. It should be a pretty cool event, we actually got a little pre-coverage in the Guardian. http://www.sfbayguardian.com/pixel_vision/2010/11/16/sf-local-artists-purpose-within-reach

I just set a price of more than I really want for it. Something worth a few hundred I'd add something like $50 to my real asking price. If they wanna haggle I'll give them $25 off and if they're really stubborn I'll give them $50. Last time I sold a lens the guy didn't haggle and gave me that $50 more than I expected.
