How to take a good picture in bad lightning

Put the Sun to your back, Use the flash, Use a tripod it's very important to keep your camera steady to avoid blur, Put your digital camera on manual settings and set aperture to the possible lowest number, Boost your ISO, Be careful about auto-focus and last but not least move closer to the light source. http://wishandco.kr/

I notice the question said bad lighting, so maybe not just lack of light. One example of bad lighting is low ceilings with those little round lights that should be warming food at a dinner, not illuminating a dance floor. Avoid taking shots when people are directly under those lights. Wait until they are between the lights or at least off to the side of the light. If those are tungsten bulbs, try changing your cameras white balance using the color temperature setting. You may need to go down to 2700K before things look right.
See if your camera has "rear sync" or second curtain sync for the flash. Set the exposure based on the room light, then take a flash shot of two people dancing (you should be too close to fit more than two). You should see a motion blur trailing them, then they will be sharp, frozen, and well illuminated by the flash.

You can find the manual here. They have some suggestions for shooting in low light:

• Set scene to "NATURAL LIGHT" Capture natural light indoors, under low light, or where the fl ash can not be used.
• or set Scene t "PARTY" Capture indoor background lighting under low-light conditions.
