Looking carefully at both images, you can see that the stacked image on the right looks cleaner than the other. How would DeNoise AI, uh, stack up against this tried-and-true process that night photographers and astronomers use? I used a stack of 15 photos for the comparison. I’ve done this for several years to reduce the noise. I did have several hot pixels, and it did not remove those, but everything else looked great. Looking at the comparison, you can once again see that DeNoise AI has significantly reduced the noise while keeping the details of the rock and stars intact.
#TOPAZ DETAIL VS ISO#
The 4-panel comparison in Topaz DeNoise AI, applying noise reduction to a single high ISO exposure.Ībove, I chose the Low Light from the 4-panel AI Model options. I realize that no one looks at their photos this way, but for the sake of comparison, it makes it easier to see. We’ll compare all the photos at 200% zoom. I use an app called Starry Landscape Stacker (Mac only) to combine the images. These random elements are rendered invisible in the final image. However, it removes random elements such as digital noise as well as elements that change from one exposure to the next, such as airplane trails. The final image shows the parts of the exposures that are consistent through each layer, like the stars. The stacking process is based on the median of all the stacked exposures. Stacking is when the photographer uses the same camera and tripod setup and the same settings and takes several photos in succession. Many people love to stack photos to reduce the camera’s digital noise.
Topaz DeNoise AI, and a stacked photo vs. From the same camera and tripod setup, I wanted to compare two scenarios - a single exposure vs. It’s also a nearby place to photograph the night sky. After all, it’s the location of the epic slow-motion battle between Captain Kirk and the Gorn lizard-man. It’s a special place, particularly for “Star Trek” lovers.
Vasquez Rocks is a state park north of Los Angeles. I decided to really challenge it even more at one of my favorite locations nearby, Vasquez Rocks in Agua Dulce. Its ability to reduce noise while keeping the stars sharp and intact was impressive. Previously, I had had used Topaz Labs DeNoise AI with a high ISO Milky Way image, which I wrote about here.
