The x-ray image is formed when the x-rays travel through the patient onto the cassette. The x-ray cassette is made with a Gelatin, bariums, and crystals the light up when interacted with x-rays. Depending on how much of the x-ray is absorbed by your body, the cassette will light up in different brightnesses, causing certain parts of the film to become slightly exposed. A fully exposed x-ray film will appear black will appear black when processed, while one the hasn't been exposed in any light will show be very light, and only show the color of the film, which has a slight tint, and a properly used x-ray film will show black, white, and different shades of gray depending on the thickness of bones, and tissue mass.

Why do x-rays leave a black hole?

If matter falls into a black hole, it will be accelerated so much that it will emit x-rays. These are emitted before the matter reaches the event horizon, that is, before it is "inside" the black hole. Any x-rays emitted after the matter passes the event horizon will stay inside.
