Lateral Chromatic Aberration corrects differences in the image magnification and image size due to different color wavelengths at the image margins.
The Red compensation slider adjusts the magnification of red light and the Blue compensation slider adjusts the magnification of blue light.
The Noise Reduction panel offers tools for reducing image noise.
Random noise reduction reduces random noise (especially electrical noise visible in dark areas).
