Taking shots in artificial lights When you shoot in artificial lights, the effects can seen as: 1. When the light is Flourescent (White), the effect is greenish. 2. When you shoot in yellow lamps, the effect is yellowish. My question is...do you get these effects even if these lights don't fall on your camera lens? If yes, why you dont have a yellowish tinge in the shot when you shoot a town during night?

The light falling on the lens doesn't matter. It is the light that is falling on your subject that makes the difference. The lights of a town are a mixture of many different light sources. Some tungsten, some vapor, some flourescent etc.. A great deal of these color casts (when dealing with negative film) are at the mercy of whoever prints the image.

Bipin, Light from man-made lamps is not the same as daylight. It is a different "color temperature" and will lean toward a particular portion of the spectrum. Fluorescent, arc and metal vapor (sodium, mercury, etc.) lamps are a particular problem because of the spectral "spikes" they have of a very specific color. Most film is "daylight" film color balanced for daylight. When used with man-made lighting it results in the color casts you mention. With color negative film, the print processor can correct for much of this when making the prints. However, as Jeff mentions, you're at the mercy of the person making the color balancing decisions for the print and their desire/skill at doing this. -- John
