Wide Angle Lens Causes Shadow In Indoor Pictures

Discussion in 'Digital Cameras' started by Abraham W. Siff, Apr 24, 2004.

  1. I have a Canon PowerShot A40 camera . In order to take wide angle
    indoor pictures for my wife who is a real estate broker, I bought a
    CanonWC-DC52 Wide Angle Lens and the Canon LA-DC52B Lens Adapter.
    I have had no problems taking outdoor pictures, but when taking indoor
    pictures, there is a shadow in the lower right had corner of every
    picture. If I remove the wide angle lens package, I can take pictures
    with no such problem, but I lose the wide angle capability which was
    the reason for buying the wide angle lens.

    Can anyone help?

    A. use a tiny mirror like you get in a lipstick case to redirect the light
    up to the ceiling, you should get a better light anyway than direct flash,
    you may have to use a tripod too.

    B. or using a tripod just shoot without the flash.

    C. get a camera that has a hot shoe so you can attach a separate flash that
    is several inches away from the lens, hopefully one with a tilt so you can
    bounce off the ceiling or side wall for better lighting.

    D. see if a separate slave flash will work, you can buy some cheap $20 flash
    with a built in slave eye, one or two of those should compliment, over ride
    the built in camera flash and/or at least fill in the little shadow.

  3. I also have this problem with an a60, but utilize two small slave flashes. I
    found them to be available in most camera shops for around $14.00. Works
    great, and solves the problem of the lower right side of the photo being
    under exposed.

    It sounds like a shadow from the internal flash. You'll need to either
    shoot without using the flash, or use an external flash.

  5. If the camera doesn't have a "hot shoe" that's pretty much it.
    My wide angle is huge compared to the standard lens (77 mm filter
    ring). I use an offset flash in the hot shoe. On the D-70 the built
    in flash will create a half moon shadow all the way across the bottom
    of the frame and up somewhere between 10 to 20% of the frame when
    using the 12-24 mm lens at 12 mm. The off set flash shows no such
    shadows. Of course when going to an external flash you need one that
    can spread its light wide enough to cover the frame as well, otherwise
    the edges and corners will be underexposed.

  6. Thanks to all of you for your help. I also posed the question
    directly to Canon and they confirmed your explanation of the cause of
    the problem and suggested turning off the flash when shooting with the
    wide angle lens. Since that is not always practical, e.g., when
    taking pictures in the evening, I am going to look into the slave
    flash approach.
