consider. The new algorithms have largely overcome the tendency of conventional
wavelets to create artifacts like halos, ringing, or color bleeding in high-contrast edges.
Noise Ninja achieves smooth results, even in low-ISO images.
State-of-the-art noise reduction requires device profiling because noise differs from one
device to another. Noise Ninja has all the necessary data to tell it how different cameras
behave at various high-ISO levels, and it provides the correct filtering to counteract any
tendency to accentuate noise at certain color frequencies. Equally, it provides separate control
over color and luminance channels—another necessity for advanced noise reduction.
Noise Ninja is available in stand-alone and plug-in versions.
