Three camera features that contribute to your ability to take good pictures indoors

1) ISO range (The higher the ISO number, such as ISO 800 or 1600, the more capable the camera is of capturing an image in low light without long shutter speeds.)

2) Lens speed/brightness (When I say lens "speed" I don't mean mph, but the largest/brightest f-stop on the lens. A lens that can open up to f2 is faster/brighter than an f4 lens ... and an f2 lens is better able to capture images in low light at faster shutter speeds than an f4 lens.)

3) Flash (Built-in flashes are okay for close-range snapshots within a few feet of your subject or "fill flash" outdoors, but for real quality lighting you need an external flash ... and a camera than can use an external flash.)

A "possible" fourth feature than can help indoors is "image stabilization" (IS) or "vibration reduction" (VR). However, IS and VR only help reduce YOUR movement while holding the camera during long shutter speeds ... IS and VR to NOT reduce SUBJECT movement. So, if you are taking a picture of a building at night you can us a camera with IS/VR and hand-hold the camera with a long shutter speed like 1/4th sec. But if you try to take a photo of moving people with your camera at 1/4th sec shutter speed the people will be blurred and the background will be sharp ... because the shutter speed was not fast enough to freeze the subject motion.
