Camera Raw- Noise Reduction

Hello Everyone.
When I open a Raw file Inside the Camera Raw, an If I try apply the Noise Reduction, I noticed It dose not do much, But If I saved the image, and reopen it again In camera raw, specially a small Image the the Noise Reduction works well.

ACR 8.x works differently depending on which version of PS is hosting it.
That Preview checkbox up top is the old method used in CS6 and earlier.
With CC and newer, there are several buttons at the lower right and a few menu options that can be used to swap between the current and previous and default settings:

  • Camera Raw noise problem in Photoshop CS6

    Opening a Canon .CR2 in Photoshop CS6, Camera Raw generates a significant amount of noise or graininess in the image compared with the simultaneously saved .JPG file.  This results in the image from the raw file being of reduced quality.  I never had this problem using Photoshop CS5. 
    Is this the result of some setting being turned on?  If so, I have been unable to figure out which one.  The only other possibility is that there is a severe flaw in the latest version of the Camera Raw plugin.
    Can anyone out there shed any light on this?

    You're using a raw converter to increase your access to more control.  Among the controls you now have at your disposal are color and luminance noise reduction.
    The thing is, what you'll want to do is to develop a set of Camera Raw Defaults that start your conversions off as you would like, then save that default so it pre-sets all the controls for each new image you open.  In my case, I have a fair bit of noise reduction dialed-in by default for my Canon EOS-40D images.
    You may also want to turn down the default sharpening, which will bring up noise in itself.  I've done that as well, as you can see.

  • Camera Engline Noise Reduction? :(

    Hi everyone,
    I unfortunately used a Canon ZR800 to record some interviews without using an external microphone. This camera is horrifyingly loud, and I had no idea (and being in-field, there wasn't much I could do at that point).
    Are there any audio experts (or non-experts, for that matter) that can recommend what I can do to keep the volume loud enough to hear the interview, but get rid of the high-pitched engine noise?

    Plan a) export your audio to Garageband.. (Export/Quicktime/Expert/.. aiff) and try the advanced tools of this audio processor, esp. the Equilizer..
    Plan b) export to Audacity, which offers a 'soap' effect (select a portion of 'noise only', let Audacity 'minus' that)

  • Is Lightroom really better for noise reduction than Adobe Camera Raw?

    That's what I keep hearing from Lightroom users (who don't use Photoshop or barely touch it).
    Which is better? or are they exactly the same? I'm not referring to a specific version, but I am personally using the latest Cloud versions of everything. I haven't tested it visually, I'm just now getting familiar with Lightroom.

    Given the same version number, Lightroom and Camera Raw have the exact same sharpening and noise reduction. The only differences in ACR and LR are usability or UI aspects, the controls and rendering are the same.

  • Any chance Photoshop itself will get Camera Raw's noise reduction and sharpening?

    I would love to have the noise reduction and sharpening from ACR 6 in Photoshop itself for JPEG, TIFF, and PSD files. Yes, I know I can open those files in ACR, apply noise reduction and sharpening, and then have it then open the files to Photoshop. But it would be so nice if we could do that without having to go through Camera Raw.

    Yes, I am absolutely saying that the noise reduction and sharpening of ACR 6 is vastly superior to any filters in Photoshop CS5.
    For those who only work only with RAW files this is a non-issue, but I sometimes prefer to use TIFF files generated by CANON DPP software or occasionally even JPEG's straight out of Canon DSLR's. Going through ACR just for noise reduction causes unnecessary color space conversions, as well as just a needlessly complex workflow.
    Perhaps you should ask Canon to make DPP noise reduction better.  I also do not think is a good idea to get too aggressive with noise reduction  and sharpening when you first bring a image into Photoshop unless you only use the image single use for a particular output device.  Your better off working with a somewhat soft image till you ready for output and then sharpen for the output devive being used.  If you use strong sharpening and NR up front sharpeing again for your output device may produce unwanted sharpening and NR artifacts...  There are several third party noise reduction and sharpening plug-ins that are better then Adobe Photoshop built in ones.  Noise reduction has to be balanced too much will loose detail masking detail is important. ACR noise reduction provides masking adjustments and works well. Third party plug-ins offer offer advanced masking features also. Photoshop noise reduction filter has a basic preserve detail slider which I presumes does some kind of masking but this is not as good at ACR masking and third paty masking.  You can of course add you own masking before using photoshop noise reduction filter. Sharpening also needs masking for sarpening will sharpen noise as well as detail.
    IMO your better off with third party plug-ins that are designed to be the best. They keep getting better there is no clear winner for all images. I'm been satisfied with NeatImage and I have only had to pay for two upgrades.  I had to pay for the addition the 32 bit plugin then and  for the addition a 64 bit plugin.  All other updates to NeatImage has been free of charge even the lates version 7 of the 64 bit plugin was no charge for me.

  • Camera raw filter 8.x artifacts (not posterization, not banding) when using noise reduction

    hi. i use camera raw filter for frequency separation, using noise reduction. And these strange lines keep appearing and messing everything up.
    What is this and how do i get rid of them. Maybe it's a bug of some sort? It looks like ACR is breaking the image to pieces and working with them individually and combining them back.
    If the sliders are not 100-0-0, the lines reduces, but is still there

    I am seeing the same thing in a random test image someone else posted of buildings at night.  The discontinuity becomes more apparent if you maximize the sharpening but it is not there in the saved result so appears to be the difference between rendering for the display and rendering for output:
    The output TIF does not have it:

  • Why is Noise Reduction only available with some raw files

    I  have been going through my CRW, CR, and CR2 raw files and have noticed that some, when opened in ACR, do not allow me to adjust all the parameters in Noise Reduction.  I thought it might be ISO related, but with a group of identically created raw files, some have full Noise Reduction adjustments while the next file will not.  The only group that offers full adjustment with all files are the newer CR2 files captured with a 5D Mark II.  Older 5D and 10D raw files are a hit and miss.
    Am I missing something?
    Thanks,
    Kim

    Another way is to just go into the Camera Calibration tab and select the 2010 process.

  • In-camera high ISO noise reduction & ACR

    I've been involved in a discussion over on DPReview where someone believes that, when shooting with a Nikon dSLR (in this case a D7000, but the model isn't really important) high ISO NR is automatically applied in-camera directly to the raw file, and this will be carried over to any raw conversion software, including third-party software such as ACR/LR.
    Now I do agree that even with NR switched off, Nikon do automatically apply some limited NR to high ISO images in-camera, but I'm pretty much 100% certain that this is not something that ACR would interpret, and so it would not actually have any effect on the appearance of the raw file when it's processed. In fact, if the high ISO NR is somehow embedded into the raw file, that would go against my whole concept of how a raw file works in a convertor such as ACR! Surely any "default" high ISO NR is just added to the proprietry part of the EXIF, and is therefore only factored in when using Nikon conversion software (ViewNX, etc)? Otherwise, the file could not truly be considered to be 'raw'.
    I think I'm right, but wanted confirmation from some of the experts on here! And of course, I'm also quite happy to be proven wrong!

    By the way, the reference I found for D7000 shows that the High ISO NR can be disabled.  See this page:  http://www.imaging-resource.com/PRODS/D7000/D7000A7.HTM
    What camera do YOU have, Molly?

    Hi Noel,
    Wow, I'm impressed with your efforts here!   Your point about blurring being a potential sign of whether or not NR has been applied to the high ISO raw files is a good one, and I agree that, based on that thinking, the examples you've found don't really seem to show much evidence of that, particularly the shots of the focus/resolution target.
    I do have a D7000; I replied as such back in post three ("yes I do" in response to your question "do you have such a camera?"), but I can see how that may not have been as clear as it should have been! I'm going to try some test shots myself to see if I can pick out any evidence of softening/blurring that may indicate NR being applied during the processing of the raw data. However, unfortunately my PC is currently being fixed as I've been having some hardware issues, so that testing won't be happening until I get it back (hoping within a week, missing it already).
    Regarding your reference that indicates that high ISO NR can be switched off, yes it can, but apparently only up to a point - here's what it states in the Nikon manual (and what has in turn sparked off this discussion over on DPR):
    "High ISO NR - option: off - Noise reduction is only performed at ISO sensitivities of ISO 1600 and higher. The amount of noise reduction is less than the amount performed when low is selected for High ISO NR" (as the article indicates, there are three options apart from off: high, normal, and low).
    As I've said previously, my understanding was that all of that had zero bearing on the raw file once it was loaded into ACR: regardless of any NR settings applied in-camera, either by the user or by Nikon bypassing the user, they were all thrown away by the Adobe raw processing algorithms, as are things like picture controls, sharpening, contrast, etc. But following my recent discussion, I started to wonder if my understanding of the raw capture process was incorrect, hence this thread.
    Thanks again for your work here. Above and beyond the call of duty!

  • In-camera noise reduction

    This question is directed to the technically knowledgeable out there and has to do with in-camera noise reduction settings. Although I'm shooting with a 1D4, I would guess the same would apply to all models. In a nutshell, is in-camera noise reduction (assuming it's enabled) applied to RAW files or just to JPEGs? If it's applied to RAW files (which is all I shoot), have any of you shot RAW with noise reduction disabled, and if so, how were the results? I tried to do a search here on this topic but was unable to find any information. Thanks.

    No, with all due respects, it is Long Exposure NR. Why would it make it worst with High ISO if it is "High ISO Noise Reduction".
    6D Manual page: 128 - 129
    5D Mark III manual page 144-145
    "Images taken at ISO 1600 or higher may look grainier with the [Enable] setting than with the [Disable] and [Auto] setting"
    With Auto setting, camera will not do LENR if the ISO is higher than 1600.
    I've tested this and it's give many kind of artifact with high ISO from time to time. Others it just gives more noise.
    Hi,
    - Great to know, thanks! It's very surprising indeed.
    LENR is supposed to remove hot pixels and noise due to long exposure. It's (sadly) surprising the in-cameras LENR may be worse than in post...
    We'll take a review about it , since shooting long exposure at higher than ISO 1600 is not uncommon for astro photography.
    I think 5D Mark 2 didn't have this "problem". Will check that too.
    - The manual tells that in-camera High ISO NR applied is lower at high ISO than the NR that can be applied in post, not "worse", sorry, my mistake.
    Thanks once again.
    EDIT: The User manual of 5D Mark 2 doesn't tell anything about this matter. The manual of 7D does, as well as 6D and 5D3 as you mentioned.
    Since I used to work with 5D2 I didn't realize the 5D3 could be different. Or at least the manual of 5D2 doesn't say the final result of LENR at 1600 or higher could be worse. Good thing to keep in mind.
    Sitll doesn't understand why the result "may" be worse, the 5D3 has enormous computing potential with the Digic 5+
    This seems to only affect if  LENR is set to "ON" / "Enabled", not to "Auto". Very likely a more agressive NR is applied in such case.
    We'll carry some test indeed.
    EDIT 2:
    In just brief tests with the 5D Mark 3 we found some inconsistency on the results between setting Long Exposure NR to "OFF", "Auto" & "On".
    We set High ISO NR, Peripheral Illumination Correction and Chromatic Aberrations to OFF, to see only the effect of LENR in JPG (not RAW yet).
    This camera (5D3) applies High ISO NR even when you set it to OFF (very noticeable in video mode).
    At ISO 6400 we didn't see a hot /stuck pixel (even when LENR set to "OFF") that appears at ISO 3200 when setting LENR to OFF or Auto. Of course "ON" deletes all hot /stuck pixels, but also increaed grain.
    We all already know that the more the sensor heats up (shooting and shooting long exposure stills - or using Live View for stills or video), the more noise we'll get in the pictures (and video).
    So far we couldn't get a "rule". Sometimes the "Auto" works better than "ON", it seems it depends on the selected ISO value and how hot is the sensor too.
    I pesonally don't understand WHY the LENR delivers more grainy images when set to "ON", if the NR is more agressive the grain should be finer than in "OFF" or "Auto", so it doesn't make sense...
     We'll test the 5D Mark 2 to compare with 5D3 in this regard

  • Why can't I see moire reduction tool in camera raw 8.1?

    Hi There,
    I have been happilly using the moire reduction tool in camera raw up until a day or 2 ago. For some reason the moire reduction panel no longer appears under the adjustment brush. The funny thing is that 1 dng file that I used the moire reduction on 2 days ago still shows that panel but no other dng files will display the panel containing sharpness, noise reduction, moire reduction and defringe. Can anyone suggest why this has happened? I've tried updating the sofware and that didn't work.
    Cheers,
    Damien.

    PSE 11 has a new 2012 raw engine but you can switch between the old and the new. In the camera raw dialog click on the camera icon. Then change Process to 2010. Then go back to the basic tab.

  • RAW files very smoothed - not caused by noise reduction

    Hi there.  My Adobe RAW-converting software has just developed a really odd problem.  I was editing files and all of a sudden all the RAW files have some kind of smoothing effect.  It's like the noise reduction is up full (it's at the default settings), but even worse.  This happens in both ACR and Lightroom.
    I can see the blurring effect in Lightroom and ACR if I zoom in to 100%, but not otherwise. I trashed the preferences for Photoshop and ACR and I also re-downloaded Camera Raw 5.6 and reinstalled it. Nothing seems to help. I did not change any settings for this to happen; it just happened sponteneously as I was editing.  Any ideas?  Thanks!

    By the way, here are two screen shots showing what the file looks like at full size in LR, followed by how it looks when opened into Photoshop.

  • Noise reduction - RAW fine tuning and the Noise Reduction tool

    Hi,
    1- If I get it right, Aperture's RAW fine tuning "Automatic noise compensation" (translated from French) option uses the camera's information to adjust the noise. Is that correct?
    2- The Noise Reduction tool is there to provide additional noise reduction, but this makes you lose some details. Is that correct?
    3- How do you use them? I often find the Noise Reduction tool a bit overkill, but that's me.
    4- This one is just out of curiosity. How does A3 compare to LR3 beta for you in that regard? In my testing, LR3 did a slightly better job (but A3 totally beats the crap out of LR2 for noise). BUT I have an old D50, and newer cameras handle noise better (especially Nikon), so does it really make a difference for a 2008 or newer camera?
    Thanks!

    I don't even have this option/checkbox in my Raw Fine Tuning brick.
    I wonder if it's due to the type of files (Canon 7D). Do you still have those 7D files I sent you? Does the checkbox appear in Raw Fine Tuning for you with them?
    I noticed this option in the manual the other day, but forgot about it until now.
    True, it doesn't have the checkbox with the 7D files. However, it as a slider "noise suppression" (again translated) in the RAW fine tuning options (and still has the Noise suppression brick).
    If you don't have this one too, have you reprocessed your images with Aperture 3? Since it has a new raw engine, it may be the cause of it.
    I find it strange that Apple didn't tout the new RAW engine on Aperture 3 new feature, it clearly is an improvement over Digital Camera RAW 2, especially in noise suppression.
    I agree the built-in noise suppression is much better than A2, but IMHO it pales in comparison with the Noise Ninja plugin from Picturecode. The key is that you calibrate a profile for Noise Ninja by shooting a color chart full screen on your computer at varying iso settings with each of your cameras. You then feed the images back in to Aperture, and tell Noise Ninja to create a noise profile for each setting. The results are amazingly good.
    Now with a lot of new cameras, noise processing is getting less important because the high iso performance is so good....but this is what makes Noise Ninja special...even when the noise adjustment is subtle, because it is working from a profile created with your camera, at the iso the shot was made at, its effects are seamless. They just announced a 64 bit plugin for Aperture 3, so no bouncing into 32 like other plugins at the moment...

  • Noise Problems in Camera Raw 6.0

    I was editing a few ISO 100 photos in Camera Raw 5.0. After editing a few I had to switch to a machine using Camera Raw 6.0. After loading my photos, I notices a very LARGE amount of noise. I can't seem to reduce the noise with the noise reduction tool, however when I adjust any of the HSL / Grayscale sliders the noise completely goes away while holding it. Any ideas? I am using CR2 files.

    I seem to remember that they changed the noise and sharpening process in ACR 5.7. Previously, there was some default noise reduction affecting sharpness, and they removed this in 5.7 onwards.
    If it's this, you'll see more noise, but your images will be slightly sharper. You may want to add some noise reduction to compensate.
    If it's not this, then I don't know what you're seeing.

  • Application of Noise Reduction to RAW files on import LR 3.x

    The Noise Reduction sliders by default are at the same setting 0 for Luminance and 25 for Color at all ISO camera settings.
    Does this mean that the same degree of noise reduction is applied to all raw files?

    I have a series of Canon 5D MKII RAW test shots ranging from ISO 100 to ISO 25,600 of the same subject. Checking the affect of the Luminace NR slider in LR shows that it is "weighted" based on ISO. The image shot at ISO 100 shows very little change to the image detail at 100% Luimnace NR setting. The ISO 3,200 shot with only moderate noise looks almost blurred at a 100% Luminace setting. I have no idea what alogorithm is used to determine the weighting versus ISO setting, but clearly there is some weighting applied. I'm guessing it is non-uniform and applied much heavier at very high ISO where noise becomes predominate.

  • Is Hot Pixel Reduction Still Happening in Camera Raw?

    Seems to me that in past versions of Camera Raw I was seeing pretty effective hot pixel removal.  Is that still in the converter?
    I was just processing some high ISO night shots and it sure seems to me that I see more hot pixels in the dark places than I used to in conversions.  But it could just be these images and the settings I am using bringing them out.
    -Noel

    Thanks, guys.  I think all is well.  The egregious hot pixels are being handled.
    I just did some very careful comparitive conversions going all the way back to Photoshop CS3.
    In the change between Photoshop CS3 and CS4 (ACR 4.6 and 5.7) there is a definite difference in the hot pixel handling, with more hot pixels showing in conversions from the latter.  Notably the detail level in conversions seemed to go up markedly at that time as well.
    However, it became clear to me that the reason I was seeing more hot pixels than I thought I should was that I was actually pushing the exposure up on high ISO night shots already, bringing out more noise than would be seen at default exposure levels.  In fact, without such enhancement the remaining hot pixels are essentially invisible.
    Here's a small portion of the same "boat parade" raw file converted with all these different versions, noise reduction completely off, and enhanced in brightness well beyond the levels I normally do just for illustrative purposes.
