I heard from a friend of mine. if you expose it optimally it won't be too obvious, meaning, you try to slow the shuttle speed, let it take in more lights but u got to be real still for the photos, as lil shake will make the photo blur. Best is bring long a stand for such shots. This will mainly apply for landscapes ba. Cos the more lights the camera take in, the less noise it will produce. so in the pics, onli the darker areas will be grainy.
