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.

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!
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.
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.
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 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*
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
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.
Thanks man, exactly what i needed! pretty new to photography. Amazingly helpful!
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.
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!
OMG I live the warm lights and feeling of this video!!!
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!
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!!
Thank you Aaron, I love your tutorials. They are not too long!! And you explain everything in a straight forward way..
Perfect in photo touching tutorial.
He is awesome, honest and great artistic!
Keep moving ahead Phlearn!
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!!
thank you kind sir, I sincerely appreciate all your tutorials.
thanks man. really appreciate this vid
This is exactly what I'm looking for! Also, thanks for the little recap/quick version at the end!
Thank you Aaron. Will be using some of your techniques.
The results are amazing! Thank you!
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!
Terrific video Aaron! Probably the best explanation I've heard on aperture, shutter speed and ISO!
Great tutorial, thank you!
Thanks for this tut, and best part is looking cool as earlier....

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 so much
It's great, thanks!
Thank you very much!
Great info!
Thank you
Your tutorials are impressively usefull, than you so much!
Very informative, thank you.
Thank you Thank You!!, question? Do I have to do this for each picture after I do one? Or after one can it do a batch save all?

Thank you the tutorial. I used it to a photo, that I made on a concert with the singer :)
brilliant u guys thank you sooooooo much!
That new Profile picture tho! I like it ;)
Thank u so much!
Thank you so much for posting this video! It's going to help me tremendously. I do have one question: would I reduce the noise of a photo before or after color correction and grading? Thanks again!
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.
Useful Tips ...... thanks
Yessss! shot a birthday party last minute and some of the photos have noise in it. Thank you!!!! New subbie.
Awesome turorial, really learnt alot. Want to get into cameras and video making. Just dont know much about them
nice tutorial, thanks man :)
THANK YOU SOOO MUCH
Thank you for sharing, not all hero’s wear capes!
Thank you!!!
Thank you for the awesome tutorial. I just scanned some film that had very large grain, the the point where they are becoming distracting. I wonder if this technique would also work in this case?
awesome! in the camera raw filter we're have a similar effect as well, but that way it's more properly hahaha
Awesooome !!!
Hello Aaron, your video helped me alot .. But here's my question
If i already used the luminance option in Camera RAW settings, do i still need to do these steps in the video ?
and, which method is better ?
thank you so much
Video starts att around 3min.. Great video!
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
Ciro
