Which are types of noise reduction in Camera Raw?

Reducing noise in Adobe Camera Raw and Lightroom (the controls and results are identical) is easy. The Detail panel provides tools to reduce two kinds of noise – Luminance (light and dark) and Color. Results can be targeted with the Detail slider into smoother (low setting) or more textured (high setting) areas.

What is noise reduction algorithm?

Digital noise reduction schemes are being used in most hearing aids currently marketed. Unlike the earlier analog schemes, these manufacturer-specific algorithms are developed to acoustically analyze the incoming signal and alter the gain/output characteristics according to their predetermined rules.

What is image noise reduction?

Photo noise reduction is a way to reduce image noise in post-processing. Photo editing software smoothes the image by evaluating the differences between values of adjacent pixels. They may use the intensity or the color of the pixel as a reference.
