I took this photo a couple years ago (it’s got a lot more snow this year). In the middle distance is the top of Mt Whitney. I was camped in the Lone Pine (California) Campground. This is a 15 second exposure at ISO 3200 taken with my Nikon D810. Below the three stars of Orion’s Belt, the bright star is Rigel. Just above Orion, the yellowish star is Betelgeuse. To the right the bright star is Aldebaran. The small group farther right is the Pleiades.
What’s new with this photo is that I used Lightroom’s new AI noise reduction to minimize the noise associated with the higher ISO and longer exposure. Below see the before and after image … zoomed in 300% so you can see the difference easier. (At 300%, you also see a little of star motion.) You see a lot of the color dots are gone … that was mostly noise. Unfortunately, a few were likely very faint stars. But mostly, I wanted to do a little show-and-tell. You can see it is smoother. Some images will benefit from this new feature more than others. Sorry, but you can’t use it on a JPG image (yet) …
Never tried this until now, must be fun to do. Living in a big town makes it a problem, to much light here in Antwerp. Must go at least to the south of our country (the Ardennen) near the French an d German boarder.
It is fun … when it works! Always worth getting out to dark skies, though.
It looked like it clean some of the noise. Milky Way Season is near, I need to try it out. What lens did you use on the photo? The Nikon D810 is nice camera.
That was taken with my 21mm Zeiss Distagon T*. Really sharp images. And you just rack it over to the stop and it’s focused at infinity.
It reduced the noise, but blurred it some.
But thanks, Ziggy. give it a try
I tried the noise reduction on PS on my latest Moon shot. I think it made a little improvement. I have to wait for a Milky Way later on this summer. Right now, the Milky Way isn’t visible until mid-night.
Love it!
Thanks, Pat!
