Reflection problems... HELP!!!!

Discussion in 'Photography' started by Cøllap§ed Lûng, Feb 14, 2006.

  1. startin to pull my hair out now... my insurance company requires photos of
    a few small paintings I own, but whenever I try taking a pic all I end up
    with is a vague image of the painting and the cams reflection in the glass
    protecting the pics.. :eek:(

    is there anyway to get round this other than removing the picture from its

    any help gratefully recieved..

  2. Don't use the flash on the camera - it will just bounce off the glass
    and directly back at you. Instead, try lighting the picture from the
    side. You might also look into getting a circular polarizer filter,
    which can eliminate a lot of the reflection from glass.

    I'd either try taking the photo on an angel but enough to still capture what
    your try to show, or put the camera on a tripod and don't use the flash but
    do so in reasonable day light..

  4. ive tried lighting the picture from the side, but the painting seems to
    loose all clarity and becomes blured.. possibly due to a half inch gap
    between the picture and the glass.
    been down the filter road laready, just ended up with a rainbow effect on
    the glass and slight distortion if the image.. </sigh>

  5. it needs to be face on.. they are being very specific.. :eek:(
    not using the flash at all and even when moved out of direct sunlight i
    still manage to get a reflection of the cam.. even moved into subdued light
    and increased the exposure time with no improvement.. :eek:(

    You could correct it in photoshop but it will reduce the image size.
    alt-t to transform and hold control while grabbing each corner to shrink
    until square. I don't know why a polarizer would cause the problems you

  7. The simple approach, as outlined by others and I repeat, is:

    1. Turn off flash.

    2. Light the picture from the sides, preferably with two lights each at
    roughly 45 degrees, on either side of the camera. Use your eyes to
    determine the positioning for even illumination and zero reflections.
    Do this in a darkened room or at night, with no other light sources.

    3. Use a tripod and shoot straight on as requested.

    If it's a point and shoot, you may be having autofocus problems due to
    not enough light. The solution to this should be obvious (more
    light/manual focus/better camera..(O:)

    I would guess that the glass is actually plastic, i.e. something like

    There will *always* be a reflection when you photograph perpendicularly
    to a reflective surface.

    What you need to do is increase the light on the subject (but not that
    on the camera) so that the reflection gets washed out. You can do that
    by increasing the light incident on the subject, decreasing light
    incident on the camera or a combination of the two. Putting the camera
    behind a piece of black felt with just the lens poking through will

    Seems to me that you could have removed the picture from the frame, taken
    your photos, and had them all put back in the time it has taken you to
    write/read the responses......

  12. Google search term: how to reduce reflections


    Solution: Use a polarizing filter.

    Won't do squat for the OP's problem.

    This is only slightly off topic, but anyway, what medium are the
    paintings and how valuable are they?

    You might want to talk to a professional framer or painter about
    whether you should have the paintings under glass in the first place.
    If they are valuable (and they must be if you are insuring them), I
    think that many preservationists would suggest that you don't have
    glass in front of them. Oils, canvas, etc. need to breath.

    Take each picture out into the sun for good light. Put them on an easel
    or similarly prop them up. Put the camera on a tripod and shoot.

    Taking pictures of paintings is a well-understood technique. Google on
    'how to photograph paintings.'

    Do not use on-camera flash. The best lighting is flat and diffuse; a high
    north-facing window (or south-facing in the southern hemisphere) on a day
    when the sky is uniformly cloudy - no blue - often works well, but if you
    have to use artificial light then 'bounce' it off non-shiny white or grey
    surfaces; bed-sheets, table-cloths, or news-papers (not coloured!) if you
    haven't got a studio with lots of purpose-made lights and reflectors.
    Don't let the lights shine directly onto the glass.

    Put black velvet or matte black card or paper over anything that reflects
    into the glass.

    Off-set the camera to one side, or up or down, so that any light reflected
    from the camera to the glass in the picture frame is not reflected back to
    the camera. Keep the camera and picture parallel so as to avoid any
    'perspective distortion'.

    If you have to use a zoom lens, try different zoom settings to get the
    least distortion. Ideally, use a non-zoom lens of 'normal' or 'portrait'
    length (ie 50mm or 90mm or there-abouts if you are using a 35mm camera).

    If you have 'manual focus', use it. Likewise manual exposure and 'white
    balance', if possible.

  17. took a closer look at the pics after talking to the artists son who
    originally framed them.. in an attemmpt to show the fine detail within the
    pics hed placed a plastic magnifying lens directly over the pictures and
    then another layer of glass within the main frames. so it was kinda like
    taking a picture through double glazing.. :eek:(

    finaly got around the problem by covering the pictures with clear sandwich
    wrap/cling film and using a hair dryer to tighten the wrap over the glass
    removing any creases. doing this defused the light enough to stop the
    reflections in the glass whilst maintaining the clarity and detail of the
    original pictures ..

    am now a happy chappy now the jobs done and I have found a new NG to lurk
    in.. :eek:)
    Cøllap§ed Lûng, Feb 15, 2006
  18. nope.. but wifeys cling film did the job nicely.. :eek:)

  20. quite valuable..
    theyre water colours on a paper base and unlike oils & canvas cope well
    behind glass.
