How to attain Perfect Exposure when shooting Indoors or outdoors

First, set the white balance. Your camera should have settings for sun, shade, flourescent light, incandescent and probably a few others. Adjust that for the type of light you'll be shooting in. Second, you'll have to pick the ISO speed. 100 is best, but you can really only use that when the light is fairly strong. If you're using low light, set it to 400 or 800. Once you've done that, you can use the camera's light meter. Press the shutter halfway, and you should get something that looks vaguely like this: -+ There should be some segment of the line blinking, it may be the plus or minus. That's what your camera is currently set to. You'll have to change the shutter speed and aperture until the blinking part gets in the center of the line. If it's blinking on the plus side, then your shot is overexposed and you need a smaller aperture or shorter shutter time, and if it's blinking on the minus side you need more light. Open up the aperture or lengthen the shutter speed. It sounds like a lot to remember, but practice, and it'll become second nature.

well one way to attain a right exposure if by following your camera's light meter it would tell then what f-stops and shutter speed your supposed to used whether your in indoor or outdoor, another way is to always setting up the right color settings thru white balancing, after you've done these your exposure surely will be fine

Basically its all about playing with the light and make it suitable to meet ur needs.......i have added u as a friend kindly accpt it..

There are really only three ways. One is to have an exposure meter. You set the ISO rating and shutter speed on the meter, push the button and it gives you the aperture to set the camera to. The second is to take test photos. From these you look at the camera's histogram. When you get a good spread across the histogram, you have a decent exposure. This can be a little misleading, though, if you have a lot of black or white in the subject. At that point, you just have to go by looks. Finally, the camera should have a built-in meter. This may not be extremely accurate, but it will get you very close. The camera's manual should tell you how to use it. The amazing thing is that as you do it more and more, you will be able to step into a room and get very close just because you have been in the situation before.

Sir your Nikon d80 has metering features, it measures the amount of light from your subject to your cmos sensor. Basically to obtain a perfect exposure the metering guide should be in the middle of + and - sign, but of course it's up to you to experiment.
