Re: X-ray effect

If a film radiograph is made of a flower the result would be something like left hand image.

The denser parts of the object would absorb more radiation and consequently those parts would be lighter the lightest parts absorbing the most radiation and not allowing it to reach the film. The less dense parts will allow radiation to pass through and therefore blacken the film more.

If the x-ray film is then contacted printed a result similar to the right hand image would result.

The problem with these images is that where leaves overlap it should show lighter as the radiation will be absorbed more therefore the effect is just effectively a negative. You may be able to create better images by trying solarisation techniques

EDIT: If you really want to create a similar look without the expensive x-ray equipment. It might be possible to mimic the effect at the shooting stage by strong backlighting of the object. Creating the effect of the passage of x-rays through different densities of the object. Problem is likely to be that some areas will be just too dense for light to pass through thereby only recording as totally blank areas - but areas like petals should respond well
