How to Reduce Noise in Photoshop
The best way to reduce noise in an image is to shoot with a low ISO in camera. The camera creates an exposure based on three values - ISO, Aperture, and Shutter Speed. ISO is the only variable that will result in noise. Ideally, one would adjust the shutter speed and aperture (to let in enough light to create an exposure) at a low ISO to prevent image noise.
The best ISO settings to use for lower noise levels are 100, 200, 400 and 800. Anything above that is likely to create noise on the image. Cameras are getting better all the time, and there will come a day when ISO 6400 looks perfectly clean, but until then, keep ISO as low as possible!
Reduce Noise Filter
The first step in removing noise in your image is to use the 'Reduce Noise Filter'. In the 'Reduce Noise Dialog' one can control strength, preserve details, reduce color noise, and sharpen details. The strength of the filter determines how much it reduces noise - go as high as you need to remove noise, but don't over-do it. Bringing the 'Reduce Noise' lower will make the filter more effective, but will also reduce detail in the image - find the balance that works best.
If there is a lot of color noise, use the 'Reduce Color' noise option to remove it. Also, there is an option in 'Advanced Settings' to reduce noise on each color channel individually. 'Sharpen Details' will add artificial sharpening to your image after the 'Reduce Noise' filter is added, so it's best to keep this at zero.
Using the Surface Blur to Reduce Noise
If there is still noise after the 'Reduce Noise' filter is used, adding a Surface Blur may help. The key to using a Surface Blur to reduce noise in photos is to balance the radius and threshold. If the threshold is too low, the image will not be effected. Threshold controls where the blur will stop. It uses differences in tone to find edges, and tries to preserve those edges. The higher the threshold, the more separate elements in the image will blur into each other. The Blur radius determines the area that will be blurred - the larger the radius, the more blur.
It's best to bring both of these values as high as possible without destroying image details.

What I love about these videos is that you go into detail and explain exactly what's going on. Most other tutorials only go as far as telling you what tools to use and not why you're using them.
This is one of the most common tasks in image manipulation but until Phlearn covers a topic I'm not satisfied regarding the informations I have about it. Thanks for yet another awesome video!
There is a much better way. I zoom in about 800% and adjust hue, saturation, and value on each individual pixel. It takes years, but there is no loss of detail.
lol
tutorial on that please :P
A. Lincoln Hahaha
Can you link or upload a tutorial please?
You work your way through 2 073 600 pixels in a normal HD image? :P
Great job! I like how you explain the process in the beginning, giving us the 30,000 ft view, and how you do a quick overview summary at the end. It makes it helpful when we need to go back for a refresher on one of your lessons. Great work Phlearn!
I take pictures (I not consider myself a photographer, kind of a hobbyist maybe) of classical music concerts and I really struggle with this things. First, because in my college they don't let you take pictures been really close to the stage because you can distract the artists and also the public, so since I didn't have a lot of money to buy a lens that would let me take pictures from a far, I buy a super zoom camera. Also, in classical music people tend to like more pictures with no motion what so ever so low shutter speed is not an option. Finally poor lighting and not able to use extra lights make it worst. This was really useful thank you.
I literally today, came across this problem and was like damn, the reduce noise filter isnt enough. Thanks guy this is a real life saver for my shoot.
I had 2 wedding images of a mother facing her daughter pulling on the veil and had to shoot it in such low light that I just couldn't get rid of the noise no matter what!!!! You just SAVED my wedding! (I tried LR too) I'm always telling folks about your channel...and I watch all your videos....their the BEST!!!!!
they're*
Ahhh once again Phlearn saves me. Love the "in conclusion" stuff at the end too! Very helpful for when I forget part of the process and I just need a quick skim through! Keep up the good work.
I really appreciate this tutorial. Not only did you teach me about noise reduction, I learned about the ISO, Aperture and Shutter Speed settings on my camera - something I was having issues with! Thank you!
Mr. Phlearn your tutorial was awesome and very helpful. Very informative, easy to follow and fun to watch! Please continue to make more! They are truly a blessing! Pray all is well! grace and Peace!
Perfect in photo touching tutorial.
He is awesome, honest and great artistic!
Keep moving ahead Phlearn!
OMG I live the warm lights and feeling of this video!!!
The results are amazing! Thank you!
Love your tutorials. Usually find it hard to make it through whole tutorials but never have that problem with yours. Thanks for all the info!!
I liked the last step of reducing the opacity of the group. looked a little strange to me after all the filters. Bringing back a little bit of the noise seems more realistic. I would even go as far and say, that maybe only reducing the color noise makes it look more "analog grain-ish" which would also be a nice look, i guess. Thanks for the episode! This surface blur thing is genius!!
Terrific video Aaron! Probably the best explanation I've heard on aperture, shutter speed and ISO!
Thanks for sharing. I always like your tutorials.
Thank you Aaron, I love your tutorials. They are not too long!! And you explain everything in a straight forward way..
Thanks for explaining it so detail. This is the first video I found about reducing noise that I actually understand how and why we chose this and that function or %. Really helpful for a beginner like me
That is the best explanation of threshold that I have seen! Thanks for that.
Awesome. Your videos are so helpful. Thanks a million!
Great tutorial, worked like a charm.
brilliant u guys thank you sooooooo much!
Thanks man, exactly what i needed! pretty new to photography. Amazingly helpful!
Thank you so much. This helped me actually understand what to do. I made my pic look awesome!! with your help. Thank you
Thank you so much for teaching. Thanks to your vídeo I was able to restore a picture which initially had halftone dots AND a lot of noise. Thank you so much for the noise removing explanation.
So so helpful!! Thank you so much!!😊
Nice video and easy to understand. Thank you.
Can always trust that iam going to get good tips tricks and tips from you . Keep up the god work
This is exactly what I'm looking for! Also, thanks for the little recap/quick version at the end!
Thank you for this nice tip with the surface blur, it's amazing what you did with this image.
I also like your new position of the table in the Phlearn office and the warm lighting.

Thanks for the great tutorial!
This is a really good tutorial and does a good job of covering a couple of key techniques to reduce noise in post along with reminders to avoid noise in the first place. The suggestion to use the opacity is a good one also. I'd take it one step further and suggest adding a layer mask on the surface blur layer. I use that technique frequently for shot under the Friday night lights in the fall. It's great for reducing noise on flat surfaces like helmets, jerseys, skin, backgrounds and so forth but gives you an extra level of control over edges/transitions giving the appearance of sharpness. Enjoyed this one Aaron!
thanks Aaron ! really helpful your video
I like this video .Now I know how to work on old damaged photos. Thanks a lot for this tutorial.
Thank you Aaron. Will be using some of your techniques.
thank you kind sir, I sincerely appreciate all your tutorials.
Thanks a lot my man! Keep up The amazing work!
Super usefull video! Thank you!
i like the reduce noise one. the other day i found another way using the raw filter thing and it's pretty helpful almost similar to the reduce noise
Thank you 😊 This is exactly what I was looking for 👍👍👍 Great Tutorial and really helped me A lot ❤ Love your tutorials 😊👍💖
Your channel is awesome. So glad I found it, I've learned everything I know from this channel!
Very helpful tutorial Aaron... Thanks man.
Love it! Love it! Love it! Waiting for this one.
FANTASTIC!
Learned alot this episode, thanks again Aaron
Great tutorial, I bet we'll live to see common cameras with ISO that doesn't add any noise up to great numbers.
+Manny Calavera The tendency goes that way yes but I think I be dead before it happens.
Wow....this video just helped me clean up many of my photos. Thanks very much for posting! Thank you Aaron Nace.....another informative video to help us wannabe's :0)
Thanks for this tut, and best part is looking cool as earlier....
Useful Tips ...... thanks
Just like magic. Had to subscribe after that
Nice tutorial! I liked the new angle of the room...
Thank you Aaron, very helpful how to do it correctly !!!
Great info!
thanks man. really appreciate this vid
Applying a light smart sharpen at the very end often helps reduce and haloing or soft edges that may have come from the surface blur.
Please do more videos on how to shoot & edit for concerts photography.
Very good tutorial
Awesooome !!!
didn't know this until now - thank you!
Super cool
Nice! Good Episode.
You Phlearn something new everyday
Good explanation.
Yessss! shot a birthday party last minute and some of the photos have noise in it. Thank you!!!! New subbie.
thank you for the video I was really struggling with noise for a wedding I shot with horrible lighting
Thank you for the video! You're a very good teacher!
Thank you for the tips, they should help a lot!
Hi Phlearn Photoshop and Photography Tutorials. I was wondering if you would do some reviews on camera equipment. I would love to see some budgets guides ( mainly on motorized dollys or cameras) would you be open for that?
Surface blur FTW :) Great tutorial
nice video and channel!! ;)
Hello from Brazil
I love the channel and low poly art. A video on that would be sweet.
You guys are amazing
Awesome turorial, really learnt alot. Want to get into cameras and video making. Just dont know much about them
awesome tutorial! I'm gonna try this!!!! It really helped me thanks!!!!!!
Video starts att around 3min.. Great video!
It's great, thanks!
Thank you very much!
loved it bro
Your tutorials are impressively usefull, than you so much!
Thank you for sharing, not all hero’s wear capes!
great vid as usual. I want to restore my old grandparents wedding photo, their wedding pic is sooo old and even have cracked in the middle. Is there a way to retouch it? Would love to see if u can bring episode of restoring an old pictures.
Great video. I'm using ps to restore old movie posters and sell them.
thankyou 4 tutorial
I think it's better to reduce noise more selectively. Usually the noise more in your face in the shadows so I use "blend if" to be able to get more noise reduction in shadows and less in highlights. No I'm not good at English ;)
Very interesting !! Thank you so much
Excellent video. That's going to help me a ton.
Hello Aaron! It would be great to have some videos to improve macrophotography because it is usual to have high ISO values. Thank you and you´re a cool teacher.
My quick and dirty solution when working in camera raw is adding luminance and then adjusting the mask and sharpening to add detail back
Aaron, the third angle of Exposure Triangle is not ISO but light. ISO is just post exposure gain regulation. Iso is not increasing sensor sensitivity cause this one is constant.
lovely
awesome! in the camera raw filter we're have a similar effect as well, but that way it's more properly hahaha
I think using the blend if function to reduce noise in darker areas only would be a great tutorial. There are others on UA-cam but Phlearn would do a better presentation.
Aaron I appreciate you papa.
Great...
Curious why so many "experts" are still saying ISO is the the sensitivity of the sensor. That's just false. And it doesn't matter if that helps people understand it, it's still incorrect. 1) ISO is camera model specific and isn't actually standardized despite being an acronym for International Organization for Standardization and 2) it is literally a post image multiplier of the pixel values. It has absolutely nothing to do with "sensitivity" of the sensor and saying that it does just propagates the misunderstanding. For those that want to explore this further check out Tony Northrups videos on ISO.
Man, I really want a new office tour Aaron!
My hero
THANK YOU SOOO MUCH
Thanks
Thanks, Aaron, for another cogent, concise and informative video.
Some of the comments (below) defy belief and I sometimes wonder how the human race has got as far as it has with minds that are still in the australopithecine stage of evolution!!
As my teachers used to say: READ the question!!!! i.e. it's about "How to Reduce Noise in Photoshop"
Cheers
