why are my pictures dark when i zoom in?

Answer 1

Zoom lenses, unless you spend some serious bucks, are variable aperture. (The aperture is the hole in the lens that lets light in to make a picture.) Variable means it is "faster" at the wide end and "slower" at the telephoto end. Slower equals less light getting in to make your picture, hence your image appears darker.
Also, you are probably using a flash indoors. The flash on a point and shoot will cover maybe 8 to 12 feet. Although you can zoom in to make action 30 feet away appear closer, your flash still only reaches 12 feet adequately. So there isn't enough flash power to illuminate your subject. Zoom with your feet when possible.

Answer 2

It's probably the aperture of your lens. In most standard lenses the aperture size varies with focal length, for example the nikkor 18-135mm f/3.5-5.6 is a good lens, but if not used properly can result in lackluster images. The aperture is not constant throughout the zoom range, and where lighting is a concern, the two stops will have a darkening effect. You can usually retain your exposure by using a different mode, like aperture priority. This will automatically set the shutter speed slower to compesate for the smaller aperture. Or if you can bracket your exposure, set for a +1/3 EV. All of this is assuming you have a DSLR.

Good question here. A wide angle lens (45mm or higher) covers a lot of landscape in a photo. It also lets in all the light in that same area. Zoom in, and you reduce all that landscape. You also reduce the light. You only have the light from that narrowed area around the subject - like looking through a keyhole. In those cases, you need to increase the exposure time. This will probably require a tripod to keep the camera still while the shutter is open. Good luck.

This is a hard one, I know what you mean though. Basically you have to remember one thing light works in fours. When you are closer to a dimly lit place due to your lens, It's going to be a multiple of four times dimmer. This works the opposite as well. But no matter what light works in fours. So you need to use candles, a flashlight, a car flare, or a flash, especially a mobile flash unit on a tripod man, there's no other way around it. My teacher Mike Credon told me this, I had noticed it before because my folks have a hellava nice zoom lens, and I practiced like crazy with it whenever I could. All things considered, I never really use the thing. And thinking about it I knew my teacher's answer was the only rational answer. Older people really know stuff.

Because you didn't use Expodisc White Balance Filter,this filter was correction different lighting and colour balancing,

You don't get enough light into your sensor. ~
