manel_soria Posted July 22, 2005 Share Posted July 22, 2005 Just a bit of fun. Who knows how was it made ? http://www.photo.net/photo/3563169 Maybe it is too easy ? Link to comment Share on other sites More sharing options...
peufeu Posted July 22, 2005 Share Posted July 22, 2005 Hey, you're a pretty fast shooter ;) Methinks the border of the frame hides a flash cable connected to the "victim" camera... Link to comment Share on other sites More sharing options...
dan_brown4 Posted July 22, 2005 Share Posted July 22, 2005 Uhm, just pull the camera half way through a shutter cock cycle, push the advance lever back in, and take the pic at your leisure? Link to comment Share on other sites More sharing options...

manel_soria Posted July 22, 2005 Author Share Posted July 22, 2005 Of course it was a flash involved.. but how ? Link to comment Share on other sites More sharing options...
Robert_Lai Posted July 22, 2005 Share Posted July 22, 2005 That's what the film would see if you set the shutter speed faster than the X synch speed. If X-synch is 1/60, and you set the shutter speed to 1/125, then only 1/2 of the frame is uncovered by the time the flash goes off, as the second shutter curtain has already travelled half-way across.

Robert_Lai Posted July 22, 2005 Share Posted July 22, 2005 I agree with Pierre. Take X synch cord, have it come around the camera to a flash unit which illuminates the Nikon F. Set the F's shutter speed to 1/125. Second camera which takes the image is set on B. You have the entire setup in a dark room. Now, fire second camera (B). Fire the Nikon F with your finger. Flash goes off when the shutter is at the half-way mark, as stated earlier, to make the exposure. Close the second camera's shutter. Turn on the room lights. Develop the film, scan and post on photo.net. Link to comment Share on other sites More sharing options...
albert_smith Posted July 22, 2005 Share Posted July 22, 2005 <I>Of course it was a flash involved.. but how ?</I><P> The flash used to take the photo was triggered by the camaera in the photo. The flash was connected to the F with a pc cord (just out of the frame to the left) and held at the location of the camera that took the photo. The camera that took the shot was probably used open-shutter (on "B" setting) in a dark room.<P> After the set up was composed, the lights went out, the camera with the film was opened via the "B" setting, the person pressed the shutter on the F to a non-sync'ed speed (so that some of the shutter was still in the shot), and the flash fired by the "F" exposed the film in the second camera. After this, the taking camera's shutter was closed and the lights came back on. Link to comment Share on other sites More sharing options...
albert_smith Posted July 22, 2005 Share Posted July 22, 2005 Robert, I was composing my answer when you posted yours. I was not copying your thoughts. Great minds... ;-) Link to comment Share on other sites More sharing options...
manel_soria Posted July 22, 2005 Author Share Posted July 22, 2005 Ok, that was it. Except that a second flash was needed to illuminate the subject being "photographed" by the F body. The light off is not really necessary. I hope it was at least a bit interesting... This was the same idea but with a FM2 and a nicer "subject" http://www.photo.net/photo/3099212 Next question: This is possible only because Nikon F can be used beyond synchro speed, say at 1/125. This is not the case of F3, that is so clever that refuses to shoot faster than 1/80 with a flash attached. Would it be possible to catch the travelling shutter of F3?? The answer (my answer) at the end of August.. I'm going out of civilisation for three weeks (!) Link to comment Share on other sites More sharing options...

The shutter does not even know the flash is there when it is not "talking" to the camera via the dedication terminal contacts. Link to comment Share on other sites More sharing options...
manel_soria Posted July 22, 2005 Author Share Posted July 22, 2005 No, that is what I thought, but it knows it, even using the sync wire !But there is a way to do it.. For the 801 there is no clean way, it refuses to fire with the back open. Link to comment Share on other sites More sharing options...
albert_smith Posted July 22, 2005 Share Posted July 22, 2005 <I>No, that is what I thought, but it knows it, even using the sync wire ! </I><P> Boy do I feel stupid! It is not the flash, it is the open back. I forgot that other half of the equation. Yes, you are right, the F3 reverts to 1/80th when the back is open, and for the first few frames to keep the action quick when loading film in the dark.

ellis_vener_photography Posted July 22, 2005 Share Posted July 22, 2005 "Except that a second flash was needed to illuminate the subject being "photographed" by the F body. The light off is not really necessary." A second flash is not needed. It isn't like what you see through the open film gate in the Nikon being photographed is exactly fully lit. here is one way to do it Set Camera ( A) being photographed on a tripod and choose a shutter speed shorter than the flash sync for that camera. Connect sync cord to A and to flash. Set up camera (B) that will take the photo. Set B to bulb or any long exposure setting. turn off lights in room. push shutter release on B andthen push shutter release on camera A, openign that camera's shutter and firing the light.

mr.wind-upbird Posted July 22, 2005 Share Posted July 22, 2005 What I want to know is how he got the camera to take a picture of the back of itself--and with no film in it! Link to comment Share on other sites More sharing options...
lex_jenkins Posted July 22, 2005 Share Posted July 22, 2005 Hmm... I was gonna guess two flashes, one on an optical trigger, the other hooked up in the sync socket with the socket set to the wrong sync. I was overcomplicating things, as usual.

dennis lee Posted July 22, 2005 Share Posted July 22, 2005 Hey Manel, Did you post this question somewhere elso too, or did I respond to it in this forum and never hit the send button? My point was, I used to do this at weddings and events when lots of other people are taking pictures. I open to bulb or something kinda longish, at f8 or so, focused on my subjects and wait for someone elses flash to go off. It's a lot of fun, you are using someone elses timing but your own framing, and who knows where the light is going to come from. I've only done it with film, I imagine digital will make it much easier. Althought film has a bit more latitude for the erratic exposures. Link to comment Share on other sites More sharing options...
