    Hey guys,

    Here it is :
    there is a container where it contains " many white plastic covered items " , so when we apply LED lighting from the top to the container , the parts inside are getting reflected so the camera cannot able to capture it properly because of its reflections.

    So please suggest me good lighting conditions to make it more clear and more informative


    1. Infra LED
    2. Ultra violet Light
    3. Background is not possible, since because it a closed in all sides except from top ( side , bottom )
    4. polarized Lens / filter

    Welcome to APUG.

    You may be able to improve the situation somewhat using a polarizing filter. It may also help to combine that with using lighting filters to polarize the lighting at source.

    Adjusting the direction of the light may also assist.

    Have you tried "tenting" the container?

    no tenting is used, as people wants to take the plastic wrapper from top,so its open pas..but all the other sides are covered .

    What do you think about IR Light / IR Camera

    You must polarize your light source and polarize the light coming into your lens such that your camera cannot see your lamps. This way, light shining on your subject and not reflecting directly off of a shiny surface is seen because its polarization pattern is randomized by the irregular surface reflections of a nonspecular surface, whereas specular surfaces will not be seen as much because they will preserve the polarization.
    This is a technique used to shoot a lot of shiny objects such as pottery items. It's very important to show their patterning without so much surface reflection, and polarized light helps with that.

    You will need to set the polarizer on the flash so that it is black when viewed through the lens of your camera. If you have an SLR, this is relatively easy, but it's difficult with a rangefinder camera. Remember that you're going to lose a couple of stops of light because you're excluding so much. If your flash's polarizing filter appears black to the lens of the camera, reflections are minimized. If it appears clear, reflections are maximized. What you're doing is then illuminating the subject with vertically polarized light and photographing the horizontally polarized light coming off the subject. It works very well.

    I would suggest you hire a professional photographer.

    Aside from that, posting a photo would be really helpful, so we can see exactly what you are trying to photograph. Highlights are really useful in a photo and oftentimes describe packaging and surface texture, as well as contributing a contrast highpoint. For example, individually wrapped pieces of candy may look more appealing when shot brighter, with highlights topping out any bright colors and with fewer shadows. Also, telling us a little about the product and the photo's end use and final image size/dimensions might be helpful as well. If the photo will run really small then it may be more descriptive to zoom in tightly on the subject and use the copy to describe the container. Is this something that can be photographed outside the container, perhaps next to it? Does the product design, the manufacturer, the layout designer or the copy dictate that it be photographed in the container? Why must it be photographed in the container?

    More information would be useful.
