Notes:

So, for the case of a photograph of your vacation, the captured image is a representation of how sunlight was reflected off the scene (which consisted of many objects) then captured onto a light sensitive material called film.

For an x-ray picture of your hand from the doctor, it is the transmitted x-ray captured on x-ray sensitive material.

And Television is really a series of reflection images captured one after another, transmitted, received, then converted back to form moving images!
