Fuji Velvia and flash photography

Discussion in 'Film and Processing' started by anils, Jun 3, 2003.

  1. Hi,

    I recently shot a roll of Fuji Velvia under different conditions.
    However I found that some of the slides that I shot indoors using my
    cameras flash have come out completely dark. Under a lightbox I can
    barely make out the figures. The entire slide appears dark for all
    practical purposes. Has anyone ever experienced this? Could this be a
    problem in the slide development process or a defective film. I had
    purchased this roll from B&H and processed it at a pro lab in my
    locality.

    Thanks
     
  2. If other frames on the roll are OK, it's not the film or processing that's at fault.

    I suspect either "user error" when using the flash, or a faulty camera or flash. "User error" is the most likely cause!

    "...some of the slides that I shot indoors using my cameras flash have come out completely dark."
    Only some? It sounds as simple as your flash didn't go off. Keep both eyes open when using flash and even better is to compose the shot in the viewfinder and then, without moving the camera, look over the top of the camera to check that the flash is lighting up the scene.
     
  4. Also, mind you,
    Velvia has ISO of 50... I have similar experience.
    I think it's just that the flash did not have enough power to
    illuminate the whole area of your frame. Especially if the flash
    was weakly on-camera flash, the chances are high...
     
  5. Could the shutter speed have been far higher than the flash sync speed?
     
  6. Anil,

    A few things come to mind:

    1. Your batteries were weak and could not generate the power to
    push the flash to the necessary light output. Velvia will cause
    most shoe mounted flash heads to work hard -- and drain
    batteries quickly. I keep two sets of rechargeable batteries with
    me to avoid that problem. If I notice the flash is slow to recycle --
    time to put in fresh batteries.

    2. Your flash is not powerful enough regardless of battery
    strength.

    3. You were too far away from your intended subject. I learned
    this the hard way in underwater photography.

    4. Incompatible settings. You don't say what camera, lens, or
    flash settings were. Both the camera and flash should have
    been set to ISO 50. If the camera was set for ISO 50 and the
    flash for 100 or higher -- there's your problem. If you were in the
    manual mode I don't think we can help without specific settings.

    That should give you something to check next time....
     
  7. Thank you for all your comments/suggestions. I own a Minolta Maxxum 5 with a built in flash. Although I cannot recollect the exact settings now, I think I had probably set the aperture to a very small value and that might have resulted in not enough light reaching the film.
