<p>[QUOTE="SuperDave, post: 2925861, member: 1892"]Everything you see in the image was reflected into the lens, and since the lighting by definition cannot be absolutely vertical, some of that background is going to reflect onto all parts of the sensor. The majority of the light might bounce off the coin, but light isn't a point source and there will be light arriving from a slightly different origin point which will bounce from the background into the lens at the exact same angle as light from the part of the bulb which illuminates the coin. The background won't "bleed into" the image, it will be an integral part of it.[/QUOTE]</p><p><br /></p>
