Try changing the blend mode of the Dust&Scratches layer to Darken. You’ll find you can turn up the D&S radius to get rid of more pesky hot pixels, while retaining the fine structural detail in the landscape. Just applying a D&S filter is always going to blur some level of wanted fine detail. But a Darken blend mode helps retain it. Though the sky still needs masking out as you show.
Wish I could thank Alyn again for his perpetual contribution to the hobby. This one video solved a couple years of frustration with trying to produce the best images from noisy originals.
Thank you for sharing these techniques. I had shot 180 second exposures for a star trail photo last year and I had scrapped the two hours of shooting because once I raised the shadows and stacked the 40 images the noise was so bad. I just went back and tried your technique on the stacked image a voila! A clean image!
Yeah Alyn, great tips!! Now I can finally complete a photo with several hot pixels (i also tried to put the camera in the fridge to replicate the conditions and get some dark frames, but not perfect results). Thank you for sharing, very helpful videos like this
Alyn this is fantastic! I dislike the in camera noise reduction for the exact reason you pointed out in beginning, just takes up too much time. I have heard of the dust and scratches technique before but I really did not like how soft it made the foreground. That second method you demonstrated is like holy moly wowasauris rex. Awesome video dude!
Nice video Alyn, but one of the easiest ways to do this (and is free and good for your subscribers who don't have Lightroom) is to use the hot pixel removal tool in RawTherapee. Works fantastic and is very easy. Go give it a try with your raw images before stacking and other processing!
Brilliant tips Alyn, thank you so much. Saved me a lot of time. Dust and scratches at 1 - 2 pixels is also useful for getting rid of noise 'worms' artefacts but some older noise reduction software. 🙂
Hey man, really amazing content. Thanks for sharing your art with people like me, really appreciate it.❤️🙏 Are you gonna do a what's in the December night sky?
Hi man, thank you so much for constanting help! Can you do a video on winter milkyway and galactic arch? To me that kind of photography seems to be the top of night landscape photography today.
I always underestimated how hot pixels look horrible in my photos! Never tried the Select with color range + Fill, I want to see what happens and if I can create an action. Thank you!
I don´t know if this technique can be used in landscape astro but in deepsky astro we use dithering to remove read noise and hot pixels, once stacked they pretty much disappear.
Needed to learn about this so much for my mobile astrophotography. Thanks! Also, Can you tell how to replicate this in the sky part without selecting/affecting the stars? Like when i select the noise in sky, stars also get selected as a few of them have similar colours like those of noise? Can you help me in this?
I just got back from arches national park and all of my shots got pixels on the whole screen. what'a annoying is it showings on the rocks. help what are you best tips to do on post?
I wonder how your method works compared to Topaz Denoise AI on the low light or RAW model? There are a lot of settings in there that can be very good at cleaning up images, I find it great on northern lights shots, as well as some of my photos I've run through Deep Sky Stacker.
Hey Alyn, another great video, thanks. BTW, purchased the book during your “signing” promotion and perhaps your hands are sore but wondering if they’ve shipped to the US (WA) yet? 😝 Cheers!
Would there be any chance of you doing a tutorial to remove Hot Pixels and NOT using Adobe software? I refuse to pay for any software that has a monthly subscription to use it which means I’m still on Lightroom 5.7. My Micro Four Thirds camera (GH6) is plagued by these dreaded Hot Pixels. I found a couple of Tutorials using GIMP, including one with a Hot Pixel Removal plug-in. Not everybody wants to, or can afford Adobe software in the current economic climate and having a Gimp Tutorial may get you new subscribers to the channel as well. BTW still loving dipping in and of your book. 😀
@@hottgamerman Gold Standard as in the most customers, or because it’s the best? PhotoLabs and Topaz are equally good. PhotoLabs do a very good job of reducing Hot Pixels when it opens RAW fils. And for video work Adobe Premier is left in the dust compared to Davinci Resolve which is free. Adobe has been trading on its name for decades and offering very low licences to students for years so that when they go professional, they have to pay Top Dollar and are hooked into the product because that is what they trained in. Maybe that is the Gold Standard to keep monthly subscriptions well beyond the cost of a stand alone licence?
What is the point of hot pixel correction on de-Bayered RGB image? Single hot pixels are already blended, by demosaicing process, in the neighbor pixels.
@@AlynWallace I've had shots with a Sony camera, since it recorded on 1.44MB floppy disks, but I've never corrected the hot pixels on them... BTW, I know that some camera are not using CFA.

That's a great tip, thanks Alan! I'll pin your comment :)
Wonderful tip!!.. thats why you are the BOSS!!
Hot pixels and hot object outlines are the bane of editing night photography. Thank you again, Alyn.
Thank you very much.
There is no way in hell I see a notification for a new Alyn Wallace video without clicking on it in 0.4 seconds
Why not 0.3 seconds?
Just kidding of course!
Super brilliant trick. Having used PS for years it's always astonishing how you can use the same tools in new ways for extremely good results :D

really thanks for this workflow... my A7IV produce a lot!

Thank you!!! This will save me hours and help cut down my cursing. Now to go back to those pics I gave up on...
Thank you. Excellently explained easy to follow tutorial

So easy and obvious yet I never thought about trying that myself. Thanks for the great tip!
Great tutorial and techniques, Alyn. I’ve lost count of the hours I’ve spent cloning hot pixels out of my foregrounds!! Genuine timesaver, this. 👍
Wow ... this is a worthy content.. love you man .. thanks for the knowledge.

Beautifully explained as usual Alyn! This is a lot better than spending hours using the spot removal brush! Thank you very much!!! 😀

Great video thanks.
Very helpful. Thanks. You didn't talk about removing the hot pixels from the sky though 9without removing the stars). Is there a simple way?
Another great video and tip. Thank you.

Most useful
Very helpful, thank you 👌
Very handy! Thanks Alyn!
Have you tried any automated software for this? Is Topaz DeNoise any good for removing hot pixels in just the foreground?
Needed to learn about this so much for my mobile astrophotography. Thanks!
Also, Can you tell how to replicate this in the sky part without selecting/affecting the stars? Like when i select the noise in sky, stars also get selected as a few of them have similar colours like those of noise?

Good guide! 👍👍
Hey Alyn, I got some cool picture of the planets. Which one would you like to see?

Hot pixels? I thought I was just capturing some colorful stars 🤣👍🏼 haha

Highly doubt it. It's the gold standard of editing software
Give RawTherapee a try when you develop your images before stacking. It works fantastic! It's free!
