carsten_benni Posted September 5, 2002 Share Posted September 5, 2002 Dear Friend, Sorry for my english... Do you know any flashes with a good stroboscopic effect? I use a linhof 4x5 and a linhof 5x7. Thank you very much Best Wishes Carsten Benni Link to comment Share on other sites More sharing options...
art_haykin Posted September 5, 2002 Share Posted September 5, 2002 If you mean rapid repeating strobes, it would help to know just what power and repeat speeds you require, that is: flashes per second. Link to comment Share on other sites More sharing options...
carsten_benni Posted September 5, 2002 Author Share Posted September 5, 2002 Thank you Mr Art Haykin, I need few flashes per second, I think 5/6, 10 maximum. But I need a super rapid burst of each flash, 1/30000...40000 sec. Carsten Benni Link to comment Share on other sites More sharing options...
art_haykin Posted September 5, 2002 Share Posted September 5, 2002 My Vivitar 285 on 1/16th power can be manually triggered at about that rate. Of course, the power is fairly low. What are you shooting? Link to comment Share on other sites More sharing options...

ellis_vener_photography Posted September 5, 2002 Share Posted September 5, 2002 The old Balcar Monobloc, Monobloc 2 & Monobloc 3 all have a variable power, variable interval stroboscopic feature built in. Occaisionally you'llsee these units on the E-b*y. Bt the actual flash duration will be more in the range of 1/750th - 1/1000th of a second.<P>Another solution might come from <A HREF = http://www.lpadesign.com> LPA Design</A> the makers of the Pocket Wizard MultiMAX (which has a built in flash cycler and intervalometer) and other programmable flash & camera triggering devices.

carsten_benni Posted September 5, 2002 Author Share Posted September 5, 2002 I am shooting several house objects falling from the ceiling to the ground. May I repeat here a question I asked this morning to general photography forum, is it correct? Link to comment Share on other sites More sharing options...
scott walton Posted September 5, 2002 Share Posted September 5, 2002 Quantum X2 flashes... particularly the X with @400w/s... 20Hz 10 pops @ 1/64 power or 10 Hz 15 pops @ 1/64. You can change the Hz down and the pops up i.e. 6 Hz 27 pops at 1/64th and so on. Really works well. They go for about $1100 USD includes powerpack.

art_haykin Posted September 5, 2002 Share Posted September 5, 2002 If I understand you correctly, you want to track objects falling from the ceiling to the floor with a series of flashes. For this you'll need some sort of repeating strobe unit with sufficient power, and the ability to control the flashes-per-second. There are many such units on the market, and they range from a few hundred dollars to well over onethousand. Some are photographic, some are industrial, some are scientific, some are for the entertainment business, etc. One well known line is Strobotach, but there are others. The specs will differ on all brands, I'm sure, that is in terms of power and flash duration. Link to comment Share on other sites More sharing options...
dlabrosse Posted September 5, 2002 Share Posted September 5, 2002 My Nikon SB 24 does exactly that. They can be found used for around $200-$400 Canadian. Link to comment Share on other sites More sharing options...
carsten_benni Posted September 5, 2002 Author Share Posted September 5, 2002 Has Nikon SB 24 a strobo mode also? Do you know something about nikon sb 80 dx? Or about mecablitz 70 mz-5? Thank you. Link to comment Share on other sites More sharing options...

stephen_ratzlaff Posted September 5, 2002 Share Posted September 5, 2002 I've seen this technique used in the motion picture business. They use nail boards to set off special effects pretty quickly in sequence. You could beg, borrow, buy several Vivitar 283's and wire sync cords to the nail boards and use that effect. Depends on the camera to subject distance and aperture you're using but first I'd go into any one hour camera store and ask them for a bucket of "used" disposable cameras with built in flashes. I'd then rig up something with this "on-the-cheap" method to see how it works before spending any real serious cash. The nail boards are a pretty neat method to trigger sequences of events pretty quickly, but take practice. You have to wire one lead of the sync cord from one flash to one stationary nail in the nail board, then wire the other lead to the nail you're using to drag down the nail board (I'd insulate this nail, except for the tip). Then repeat the step above for each individual strobe you have. As you drag the loose nail down the nail board, as it touches the stationary nails, it competes the sync and fires the flashes in sequence. Kinda like a poor man's sequencer. Pretty much back to basics, but it does work. Anyhow, I'm rambling now. Regards SR Link to comment Share on other sites More sharing options...
