Because age spots are caused by damage done to the skin by UV rays, they tend to appear as small freckle like spots on a persons face. Also the backs of a persons hands, forearms, and shoulders are susceptible due to their increased exposure as well.
Dark spots on x-rays mean there is some fluid there. Fluid actually is radiopaque. Therefore, it blocks the x-rays from travelling through your lungs to the film and developing (darkening) that area. It is because of this that fluid, bones, and other structures actually appear white on an xray. Dark spots can show up due to pockets of air (hyperinflation) or even a pneumothorax (popped/deflated lung.) It is also widely known in the medical field that xrays are drawn to spots of cancerous tissue. (This is why chemotherapy is so effective.) Due to this, it could also be a cancerous tumor behind your lungs directing many of the xrays to one location, developing the film more in that area and showing up as a darker spot.
The reason for serial of light spots appearing on the measuring scale is due to an effect known as parallax error. Parallax error occurs when the measurer's eye is not directly over the scale, causing the light spots to appear in a series. This can be caused by the measurer moving their head or body while taking a measurement, or the measurer not being in the correct position to take an accurate measurement. The light spots will appear in a series because the measurer's eye is seeing the measurer's scale from different angles. As the measurer moves, the angles change and the light spots appear in a series. This can lead to inaccurate measurements, as the measurer may not be able to accurately read the scale due to the parallax error. To remedy this, the measurer should make sure they are in the correct position before taking a measurement, and should not move while taking a measurement.
