Canon PowerShot G1 X Digital Camera Review

Noise Reduction

The G1 X does a great job compensating for image noise. At the lowest ISO, our tests recorded an average of only 0.44% noise under normal light, and this figure doesn't cross 1.00% flat until the highest sensitivities. From ISO 100 to 3200, noise increases steadily and predictably, suggesting an even-keeled smoothing algorithm in use across this section of the spectrum. A more aggressive technique seems to kick in after ISO 1600, and noise levels spike thereafter, just as we expect them to. Still, even at ISO 12800, image noise maxes out at an impressive 1.55% More on how we test noise.
