HDR (High Dynamic Range) processing of your photos by its nature can result in a lot of noise or graininess in your final image. While Macphun’s new Aurora HDR 2018 for PC’s does a great job overall reducing noise, there are still times when noisy areas appear in your processed HDR. This can be caused by many reasons, but most commonly it’s due to your settings in camera (such as shooting at too high of an ISO) or any image processing you have done to your images before merging them in Aurora (such as exposure adjustments). Regardless of the cause, you can remove most of this noise by using a “Luminosity Layer”. This technique saves a lot of time, giving you consistently good-looking results, quickly.
