nicole_russell Posted November 10, 2002 Share Posted November 10, 2002 Hello- i posted several days ago about compensation problems with my Macro lens. thank you to everyone who emailed me!! The problem is while im figuring out compensation, something else is wrong- a roll of film from a Minolta had the same problem and now today a roll from the Nikon came out with a thick (soft, but pitch black dark) black line across all of my frames. Mostly it is about 1/4 of the frame, but in a couple it obliterates the frame covering it 3/4s. Does this have to do with the lens? It is not a faulty piece of equipment as it happened ealier in the week with a Minolta AF 28-85 lens. Am i on the wrong Fstop for my magnification? or what? It cant be shutter as that would be a vertical black line, not horizontal. I am using Speedo strobes as well (for those who didnt read my previous post). And was shooting around F22 @ 1/250, bracketing ranging from F32 and F16. Sorry to be flooding the board with my problems, but thank you all for helping!!!!!! Best Regards, Nicole<div></div> Link to comment Share on other sites More sharing options...
ellis_vener_photography Posted November 10, 2002 Share Posted November 10, 2002 Your problem is the shutter speed you chose; it is shorter than the x-sync speed of your <U>camera</U>. The x-sync speed is the shortest duration your shutter is fully open during the mechanical time it takes your camera to make the connection to the flash . It is definitely not a problem with your lighting unit. Which camera bodies are you using? Link to comment Share on other sites More sharing options...
NetR Posted November 10, 2002 Share Posted November 10, 2002 Hello Are you sure that the shutter moves sideways? Most Nikon cameras now have shutters that move vertically - you can see the blades when the back cover is open. The posted shot looks to me as though the shutter speed was set too fast for the flash. The aperture you set on the lens will have nothing to do with this problem. If it was the aperture, or the film, the whole slide would be under- or over-exposed. The fact that only a portion was under-exposed points to the shutter being the problem. You must ensure that you are using the correct shutter speed for the camera body.

Jerry_ Posted November 10, 2002 Share Posted November 10, 2002 You may have to keep notes and bracket one roll of film. You likely used a 1/500th second shutter speed (with the partial black area in your posted image.) If your lighting setup is requiring f32, you may consider a ND (neutral density) filter to reduce the f-stop needed in your exposures, while keeping your shutter speed at the max allowed by your camera. Most Nikons sync at 1/250th, the F5 can be adjusted to sync at 1/300th. Link to comment Share on other sites More sharing options...
bruce_rubenstein___nyc Posted November 10, 2002 Share Posted November 10, 2002 For the type of shot you are doing there is no need for a high shutter speed. A high shutter speed, for a still life, would only be used to avoid having any ambient light register on the film. I wouldn't use a shutter speed above 1/60 sec.

Michael R Freeman Posted November 10, 2002 Share Posted November 10, 2002 Nicole, Looks like a flash sync problem to me. A vertical shutter will leave a horizontal unexposed band on a portion of the film if the shutter speed is set too high for flash photos. Is your camera's maximum flash sync LESS than 1/250?

vedearduff Posted November 11, 2002 Share Posted November 11, 2002 Nicole, I had a look at your profile. If the camera you list is the FE and not the FE2, you have a flash sync speed of 1/125. As others have mentioned, the image you posted shows evidence of a flash sync problem. Try an ND filter or a slower film if you cannot adjust your flash setup to allow for a slower shutter speed. I hope this helps. Vernon Link to comment Share on other sites More sharing options...
