Google Nik Collections Define Noise Reduction Lightroom Plugin
Another killer, FREE plugin for Lightroom users. This time aimed towards reducing noise or grain in a photograph. While you can do this already with the sliders under the details panel, the Define plugin by Google Nik Collection is easy to use and seems to do a much better job of maintaining all the details. For this reason, we had to show you this Lightroom plugin and how to use it.
Dfine lets you adjust contrast and reduce color noise separately, making it easy to control the type and amount of noise reduction applied to your photo. Unique profiles are created automatically for each image to ensure that noise reduction is applied only to noise elements so more details are retained. Add noise reduction only to the areas that need it so you can maximize detail throughout your image. Control points let you remove noise selectively, without using masks.
