Two shots of Balancing Rock. One a single shot and the other a six image stack. Stacking images increases the Signal-To-Noise Ratio (SNR) effectively reducing the background noise in the image. The noise is reduced (SNR improved) by the square root of the number of samples. A image stacking of 4 images doubles the SNR, or reduces the noise in half. In this image the noise was reduced by the square root of six (or about 2.5 times).
