You should realize that photography is nothing more than an act of capturing light. The more light you have, the better chances of getting a decent picture.
On the other hand, the less light you capture, the more noise or grain the picture will have, the more chances for blur to happen, and the poorer the picture will be. Bear in mind that what is low light to you may as well be pitch black darkness to the camera already. Learn to compensate.
If you are in the dark and want to improve your pictures, move to a better lighted area or turn the flash on. If flash is too strong, simply step back and try again.
Now you know!
