Noise reduction f(ISO,Camera) ?

Could there be some kind of "Preset"
(I could prepare for my husband/wife)
so that images from a basic camera
are imported with preset noise reduction ?
I would adjust NR parameters for different ISOs.
Kind of Lens Correction f(F,f,Camera).
Out-of-pipeline ?

If you so elect in the preferences to apply default development actions by ISO AND by Camera, you can re-save your defaults using a series of shots at each ISO setting for that camera. Then when you import from that camera, LR will check the ISO and apply whatever you had previously set for defaults for that camera/ISO combination. I use this for my two cameras and it works great. I keep a separate folder for "default setting images" whereby I can always return to them if I determine I want to change my defaults moving forward.
It works well but be sure to save a default for each possible ISO setting.

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.

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!

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

Noise reduction applied to high ISO .tif files in ACR 4.1?

Evidently ACR 4.1 applies noise reduction to high ISO raw files from Canon cameras, even when noise reduction is turned "off" in the plug-in (and this results in smeared detail). I have a 5D that I bought specifically for its lack of noise in high ISO files, and I don't want a software program forcing me into using noise reduction and ruining all those marvelous details in my high ISO raw files. Can someone tell me if there is a similar problem with ACR 4.1 if you open a .tif file with it? If not, I'm thinking I'm going to use Canon DPP 3.02 to convert my raw files to .tif, and then use ACR 4.1 to quickly adjust exposure, black point, etc., all of which is awkward and slow in DPP 3.02.
Rob

No, although ACR v4.1 does apply some baseline noise reduction to many raw files, I do not think that it applies any default NR to TIF files. Lightroom v1.1 does not apply any noise-reduction to TIF or JPG files by default, at least as far as I've noticed, so I believe this will likely carry over to ACR v4.1 as well. Of course you *can* turn the NR sliders up from zero and then it will! In any case, you'd be advised to test that theory yourself just to make sure, before designing a workflow around that assumption...

Hi travojed !
Thank you for your message
I came to the conclusion that the high level "Median" (or "Dust&Scratches") destroys parts in this algorithm.
And it seemed to me that the best result (when the contours remain sharp) will be if, instead of a "median" using the Topaz Denoize (Raw-moderate), because Topaz protects the sharp contours in this algorithm.

I do not recommend using a constant value "Threshold" because at different values of the ISO get different noises

Does LR store the in-camera Noise Reduction settings in it's Metadata?

I am trying to understand the impact of in-camera noise reduction on High ISO images. To do this I have taken a series of pictures with different in camera Noise Reduction settings. I have then imported them into LR. What I want to know is whether I can see the in-camera Noise Reduction settings in the metadata stored in LR?
Thanks

If it's proprietary to the camera maker, you won't see it in LR. Won't most of that in-camera stuff be stored in the MakerNotes? If so, you can see the sort of info via Exiftools - see an example here http://forums.adobe.com/message/6155513#6155513

Canon 6d needs lots of luminance noise reduction at all ISO settings

Hi all,
I've been trying out LR 5.4 with a new Canon 6d. I've noticed a lot of what appears to be luminance noise even with photos taken at ISO 100, this requires the "Luminance" slider in the "Noise Reduction" develop setting to be at around 80 to remove. This seems extremely high for ISO 100 photos with shutter at 1/1000 and obviously good light, I wouldn't expect to have to use any NR in this situation. Oddly, pretty much the same level of luminance NR will also clean up high ISO photos, I'd have expected to need a lot more NR on high ISO photos. Some sharpening is then required as usual.
The luminance setting of around 80 gives the photos a similar look to those from the out of camera jpeg, or the cr2 file processed in DPP.
Has anyone else observed this when processing raw file from a Canon 6d in LR? Or maybe there's a setting somewhere that I've missed?
Thanks in advance

Hi,
Thank you for replying. Hopefully there are some images attached to this post, it's the first time I've posted here...
The shots are of an area of very clear sky with the stalk of a plant in the foreground.. There is a 1:1 compare of the LR default import (right) compared to my luminance and sharpening adjustments (left). There's also a 2:1 compare to show the noise a little better. I've added a shot of the detail panel with my adjustments.
Thanks,
Paul

Is there a way to apply noise reduction based on ISO value?

I shoot a lot of sports using auto ISO which means I get hundreds of images from a day with a variety of different ISO values, including all sorts of intermediate values (like ISO 280, for example). There are times when I'd like to apply LR noise reduction across the whole batch of images, but I'd like to apply it based on the ISO value of the image. For example at ISO 1250 and above, I want a particular NR Luminance value. From 640 to 1250, I want a different value. From 400-640, a different value. I know you can define some things at import time based on ISO, but that doesn't seem practical when the ISO value can be nearly anything as it would take hundreds of import profiles.
So, any ideas how to apply NR based on the ISO across a batch of images?

How do "defaults" interact with a preset applied upon import? I shoot RAW and apply a preset upon import for every import I do. If I apply a preset upon import will it override the "default" anyway? If that's the case, then defaults are of no use to me.
Yes - Lightroom presets are absolute, but unlike the default settings, presets don't have to specify all the settings. If a preset setting is specified, it will blindly overwrite the previous setting, if not specified then the previous value will remain unaltered.
DevAdjust supports relative presets: final-value = present-value +/- relative-preset-value

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.

Matt Howell wrote:
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:

Camera noise reduction

Hi I've just got a new iPhone 6, and i love it. However, I've noticed that what i see in the live view before i snap a photo, and after i snap, is totally different.
It seems apple's new noise reduction is a little too strong for my liking.
reuslting in a huge loss in depth and color and details.
On my iPhone 5, i used to be able to take really close up photos of my shrimps, and they looked fantastic. extremely detailed for a phone camera.
I expected this to be better on the iPhone 6 because of the new lens system and overall camera and phone processing power.
unfortunately, this is not the case.
The videos are better because the phone doesn't seem to apply any Noise Reduction filters after it is recorded.
can apple have a function to switch off noise reduction entirely? I would love to be able to choose.
also, please allow manual control of the camera settings! like VSCOcam and such. thank you!

Do camera profiles affect sharpening or noise reduction?

Do camera profiles (such as camera standard) affect sharpening, noise reduction? or just exposure?
I ask because my default sharpening is 50 but I recently switched from Adobe Standard to Camera Standard

No, they don't.

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:

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.
