every lowlight processing will result in grainy pics, the photographer makes the diff, if you focus well on the brightest part of the area, it will reduce the grainy effect as it takes as much light from the focused light source.
i feel lg laser focus is the world difference here, makes noobs like pros!
err sala a bit...there are a few strategies to reduce noise....
1. Expose to the Right to reduce the least amount of information/levels contained in the darkest part of the picture
2. Stacking (image averaging) to reduce noise by taking multiple shots of the same scene on tripod to reduce the noise after stacking them together
3. Use of noise reduction plug-ins such as Google's Nik Define 2, Noise Ninja etc helps to reduce both the chroma as well as luminance noise
4. Image blending by exposing for various parts in the scene allowing maximum levels to be captured and then blend all the various parts together.
