Problems taking photos of semi transparent plastic
      #702260 - 05/09/2008 14:31

I am trying to take photos of some semi transparent red and white plastic pendants I have made. I have tried lighting them from beneath with an ordinary lamp and also with a lightbox. When I look at the photos the colours are solid and you cannot tell that there is any transparency to the plastic. Does anyone have any tips?

Items I have at my disposal are white acrylic sheet, clear acylic sheet, a borrowed lightbox, digital SLR and two mini type studio lights. Any help gratefully received.

Are they on chains or something similar? Artistically arranging the chain behind them may be enough if they aren't too opaque.

Another way may be to raised them of the background slightly and allow some light to pass through and colour their shadow. Again how effective this is may depend on the degree of opacity you have. Likely to work better with items that are not to dense.

A lightbox should be the way to go, are you using automatic or manual settings on your camera? If you are using automatic overexpose by a stop or two because the camera will be exposing for the back lighting and not the subject.

Thanks so much both of you. Raising the pendants up and putting the chain behind was really simple and affective. Also lighting from underneath along with some lighting to the side worked really well. Thanks again!
