The best photographers wait for the sun to get just where they want it. Most award winning shots (color) are taken just before or after sunrise and sunset. Rarely are photos taken at high noon or there abouts there just isnt any "dramatic lighting effects" taking place at those times. The light coming form the sun suffers through various refractions in the atmosphere before it reaches its subject and the refractive values vary greatly on any give day. Variables include smog, haze, virga, pollution, ozone layers you name it. All these variables cause a different bandwidth of light to strike the subject being shot and this alters the color hue, thats why most pro photographers carry a good selection of filters, uv, haze, skylight, polarizing and many, many more. As far as exposures from cameras are concerned, you can make any color whatever you want whether its a digital camera or a film plane camera. When you shoot in segmented matrix mode, (anywhere from 4-16 light metering areas are taken into consideration by the camera) light values for the exposure are averaged over the entire sceen and wont always render the correct color. Most people shoot that way. When you use spot, your usually trying to capture an image where your subject is surrounded by dark or light areas, the background will either be under or over exposed in most cases. You can compensate for under/over exposure if you meter just off of the spot you want to shoot, hold that setting, then re compose and shoot (if your camera has that ability). You can do this in either of the exposure modes mentioned above. Some cameras have bracket metering, yet a 3rd metering method in between the two above. Only the best digital cameras offer pixel by pixel averaging for light compensation and these units run anywhere from $2,000 - $10,000 (last time I looked) and still fall short in some of the color rendering areas in my opinion. Even the low end digital cameras have settings available where you can select the type of light your shooting in. (changes the color saturation) but that is subject to each manufacturers ccd imager and their opinion of what the final color should look like. Im looking forward to neaxt week. scott#2
