    I tried the following setup:

    - person - wall distance = about 1m
    - flash (SB-600) on tripod, triggered wireless by my D70s, distance to person is about 2m, 45° angle direct/ceiling, selfmade white diffuser + built-in diffuser/widener glas (for 14mm focal lengths forseen)
    - camera D70s, 18-70 lens at c.a. 70 mm, distance to person about 3m, shutter at 1/30 (F4.5), about 90° between camera-person and flash-person triangle

    [​IMG]

    ...and unfortunatly the shadow is stil there. The light ist nice soft, no harsh shadows in faces, would say that everything is perfect, but the damn shadow on the wall behind is always there. The less the background light (200W lamp on ceiling in the middle of the room) the more noticable is the shadow.

    Any ideas? What could I try to avoid that shadow. It's really disturbing, it kills my photo (maternity photo with my wife). What am I doing wrong.

    The only way, I was able to remove the flash (from the photo) is to move the camera to left (so the 90° camera-flash angle increased), so the shadow is not included on photo...

    BTW, the photos are also quite underexposed. Not sure if I can set the BL / non-BL option for the wireless setups, too. The flash is recycled enough, the red led lamp is on...


    Thanks,

    I am nowhere a light man, in fact I just discovered that using a flash works when there is bright back-lighting !!

    However, I have tried bounce flash off the ceiling or even adjoining walls. Just a minor suggestion. I'll let the experts take it from here.......

    P.S. Show us a shot......

    4 possibilities:

    - Larger light source (get closer with the light, and lower it's power a touch)
    - add a 2nd light on the left to counter the shadow
    - add a reflector on the left to soften the sahdow
    - creative light placement and crop out he shadow Either so it's out of the frame or it is behind them. It depends on what you are looking for.

    In up close portraiture (head or bust), it is easier to control this vs full body portraits, but still if you take extra care to apply the same principals, it can be replicated. Also, it is also easy to use too much light or harsher light. I am often surprised that under some conditions even one studio strobe set to 1/8th shot through an umbrella give me too much light. Thats where a softbox comes in as the better choice.

    You mean, I should move the tripod with flash closer to subject? I tried the opposite (moved away) and of course it didn't helped. So I'll try this.

    Forgot to mention, the ceiling is 2,6m high, the flash is on 1,5m high.

    What about the fact, that the photos are (quite badly) underexposed? Any Nikon technical experts (BL/nonBL @Wireless)? :sexywink:

    You made this wonderful illustration showing your flash position camera position etc. but no example pictures showing the shadow you are complaining about.

    Jerry would know better than I, but if you have a bounce card on your flash that's going to increase the odds of a shadow on the wall... are you able to just bounce it off the ceiling?

    (oh and... btw... 498!) (lol... just realized I'm almost to 500 posts.) :)

    I had the same exact setup with the same problems. The umbrella and reflector seems to have helped, but my first time to use it was on a black background, so it wouldn't have shown much, but I can already tell that the light is much more diffused and even.

    I'm not a lighting master, but 45 degrees will probably give you "more" shadow than 90 degrees. I'd say you have to fiddle with it to get the effect that looks right for you.

    Again, Jerry would likely be better in this space. I usually work with a SINGLE on-camera flash.
