Decrease Noise
As photographers we battle noise in our images on a regular basis. Whether that noise comes from under-exposure or from using a high ISO, we find noise in many of our images. HDR compounds that problem in a couple ways, one by multiplying the noise in each single image as it combines to one and also in the tone-mapping process. As we map tones to a different value we may bring up noise along with making something dark a lighter value.
We can try some of the simple tools in Lightroom to take down noise. They have gotten much better over the years and editions. But really I have found to tame noise as good as it can be but yet not loose a lot of detail and sharpness to our images it is best handled by using a dedicated Noise Reduction Program/Plug-in. Some of the best ones are
- Nik Dfine 2.0
- Topaz Labs Denoise 5
- Neat Image
You will see noise mostly in areas of little texture such as skies or smooth water. What I like to do sometimes to keep detail in highly detailed areas, I will use a layer mask to just keep the noise reduction on the areas it is most visible and off of textured areas where noise is not readily seen
