In very low-light conditions, the built-in flash is not of much use even in high-end cameras. The flash is effective only up to a few meters away but it overexposes nearby objects and leaves farther objects underexposed. Thus it is good idea to disable the flash and use high ISO values. This induces noise but ensures that maximum light is captured. Set the lens at the widest angle so that you don’t lose light due to zoom. If supported by your camera, set the focus to infinity. Alternatively, you can use a larger aperture or lower the shutter speed. Be warned though: larger apertures will shrink the focus area and result in shallower depth of field (background blur). If the scene has no moving subjects/objects, using slow shutter speed makes sense. However, you should use a tripod for this or place the camera on a flat surface so that it doesn’t move. Use the self-timer to avoid shake during shutter release.
