NoiseControl 1 is a plug-in for Photoshop and compatible programs (both Mac and Windows) that’s remarkably effective at reducing image noise while keeping edge details and natural grain. It can also sharpen a noisy image without increasing noise, and even add simulated film grain to an image to make it appear more natural.
Topaz Labs’ reputation for easy-to-use and effective plug-ins for Photoshop makes them a favorite developer for a lot of photographers and designers—myself included—but while their latest addition, InFocus, is great in theory, it requires more experience and finesse to produce the results in the same ways as its siblings.
