 The incandescent light bulb, incandescent lamp or incandescent light globe is a source of electric light that works by incandescence (a general term for heat-driven light emissions which includes the simple case of black body radiation). An electric current passes through a thin filament, heating it until it produces light. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation. Incandescent bulbs are also sometimes called electric lamps, a term also applied to the original arc lamps.

I would have liked a slightly deeper DOF so that the whole shape of the lightbulb is sharp, including the interior element

Great coloring! Even more spiderweb would probably add more feeling to it, but it is great as it is

I like the photo, particularly the colour. The DoF does not include the base of the bulb which is a shame. On a Scientific not the title frustrated me as there is no incandescence in the photo - the only light is from the florescence!

The duotone really is effective here as well as the comp. Nice work.

Very vintage look, added by the cyanotype effect. Nice placing and focus.
