Are there any other enhancements in noise reduction tools in CS6

Are there any other enhancements in the noise reduction tools besides the improvement mentioned of the spot healing brush. Are there improvements on the click and pop removal tool and the noise reduction in the spectral editing view. Quite anxious to know...

Paul:
Welcome to the Apple Discussions. There is a hidden feature for changing the Redeye and Retouch tool size:
How to Change the Size of the Retouch and Red-Eye Removal Tool
Type Caps lockControl9
Undo caps lock
Click on the Retouch or Red-Eye Removal tool
The tab key will toggle between cursor types, a cross or a circle
The "[" and "]" keys decrease or increase the size accordingly.
NOTE: Using the "{" "}" keys will will change the value next to the circle and that represents the degree of change or intensity that the tool imparts on each pass.
Also check out the tip at the end of my signature for backing up the library database file on a frequent basis.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application, iPhoto dB file backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

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 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 Reduction tool not effective

Hard as I try, I can't see any effect in using the Noise Reduction tool. I've tried it on photos from both compact cameras, as JPGs, and also Raw images from my DSLR. I've tried some images with visible digital noise (low light, long exposure shots), but whatever I do with the sliders, it makes no visible difference to the noise level.
Am I missing a trick, or does this tool just not work very well?
Cheers.

I just tried that, but switching the tool off and on made no difference here. I did find I could type a larger number into the 'Radius' box, which takes it up to 4.00 (it goes to 2.00 on the slider). That did make a visible difference, although it just made the entire image blurry. Adjusting the edge detail only beings out the noise again.
It appears to me that this adjuster is not much more than a simple Gaussian blur with some sharpening. The effects are similar at least. Indeed, I just tried adjusting the same image in Graphic Converter (from a fresh Raw file copy), and it is very similar to using a straight Gaussian blur (radius 4 did the job in GC too), and then apply some sharpening.
The only time I've found Gaussian blur to work well is if you can switch into Lab colour mode, and apply the blur to the different channels.

Noise Reduction Tool Disappeared

Hi,
I'm using the LR 5 Beta and I'm new to Lightroom in general. I was editing some photos last night and was able to use the "Noise Reduction" and "Sharpen" tools just fine, but this morning when I went to edit the same photos (and subsequent photos) those tools seem to have disappeared completely. I feel like I'm taking crazy pills.
Can anyone help me figure out what's going on?
Additional info:
I'm shooting in RAW and I've tried opening the original file as well as several other out of camera files and nothing is showing up.

Right-click any panel header on the right panel in develop (Basic, say) and check the Detail panel to get that panel back.

Noise reduction in Aperture

Does anyone successfully use the Aperture Noise Reduction tool, or are you all using third party apps?
Paul

I use it for moderate noise, but for shots at a very high ISO (1600), I use Noise Ninja. There is a Noise Ninja plug in on the way for Aperture, which will be most welcome.

Noise reduction techniques

I took some action photos on a dark overcast day so I had to use high iso.
There is quite a bit of noise in my photos.
what is the best way to moderate the noise???? not sure how to use the noise reduction tools in LR
Is there a good plug in that will simplify noise reduction?
thanks for the discussion
diana

Diana-
In Develop Mode, zoom out to 1:1, and then go to the section for noise reduction. This is a subject about which books could be written ( and have!), but do use the sliders to bring it down till it starts to look off.... that'll probably print fine.

Noise reduction / adjust amplitude not available for mono tracks.

Hi,
If there is a better group or forum for the following questions, please let me know.
I am presently performing the sound editing and mix for a feature using version 3.0.1 of Soundtrack Pro. Though I am mixing using the surround feature, I have chosen to only use the center channel for dialog, and the front right and left speakers for everything else.
Furthermore, the picture editor (who is in a different state) sent me mono dialog tracks (he first sent me location and ADR on the same stereo track, which I could not separate for elimination or proper levels) and stereo tracks for the effects and score. The two problems I am running into are:
1. I am unable to access the noise reduction tools for any of the mono tracks. The individual stereo tracks allow me to do this. What appears to be going on? Is there a workaround?
2. Similarly, I am unable to access "adjust amplitude" under the same circumstances. Again, the stereo tracks are fine.
Any assistance would be much appreciated!
Kind Regards,
Andre

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...

Noise Reduction for Premiere CC 2014

Before the new release, I have used Neat Video for noise reduction. Unfortunately, this plug-in is not working well with CC 2014. The only native plug-in I saw was to create noise, not reduce it. Does CC 2014 have a noise reduction tool?

The Mercury Engine can use OpenCL in Radeon cards. That being said, the R9 M290X is not in the list of currently supported cards, and therefore the Mercury Engine should default to Software Only.
Adobe won't add the R9 M290X to the list of supported cards until they can fully test it. So hopefully they will add it in a future update (*fingers crossed*).
Until then, you may be better off with a maxed out 27" iMac which has the GeForce GTX 775M, which is supported. It will no doubt perform better, and yes it will be like a hot knife through butter.

Noise reduction doesn't work?

Hi All,
New user here (testing the demo). I have a moderately loud
air conditioner system, and as a result there is a constant hum.
I'm trying to get the noise reduction to work, but to no avail.
Here's what I do.
I record a clip. then select Edit Timing. Then Adjust Volume.
Then check "Dynamics (boost quiet sections), then I play with the
Noise Threshold and Ratio sliders (primarily Noise Threshold).
These don't seem to do anything, though I *can* adjust the volume
of the clip successfully.
What am I doing wrong here? Thanks!

Hi carloshl
Welcome to the world of Captivate!
Seriously, the audio editing bundled inside Captivate is
always reported as being rather anemic. I compare it to the jack in
the trunk of a new car. Enough to change the tire once in a while,
but if I'm gonna do it more often than that, I should probably
invest in a different tool.
The really super good news here is that your investment need
not be cash! There is a wonderful and totally free audio editor out
there called Audacity. You may download it by
clicking this magickal
link.
Oh, and you should probably also find a quieter room to
record in.
Any possibility of turning off the air for a brief
period?
Cheers... Rick

Sharpening, noise reduction and blurring (general)

Sharpening, noise reduction and blurring ...
I need to read an extensive and up-to-date reference about these topics in digital imaging.
I would like to learn your book advises ...
Thanks a lot.
PS. It can be technical.

Thanks Jeffrey,
I want to learn all the sharpening algorithms in the digital imaging world today (and also for NR and blurring, as they are closely related subjects with each other).
Indeed, I'm trying to understand the PS and LR tools.
And, in order to understand their tools completely,
I think I should have a solid background on these subjects ...
For example ...
I could not understand yet how the detail slider works in LR.
It is said that it uses deconvolution algorithm ... but if you ask me it looks like a smart sharpen applied to the high frequency.
Is smart sharpen deconvolution?
Looks like ... but I don't know.
Like this ...
Of course, I can use them without knowing them so much,
Just "need for knowledge"
I read Jeff's book, but I think I need more.

Lightroom, Photoshop, RAW Presharpening, Noise Reduction Workflow Help

I'm tying to determine a best practices route using Adobe Lightroom, Adobe Photoshop and Nik Software Sharpener and Dfine (Noise Management Software).
I shoot only RAW with a Canon EOS 30D with good quality lenses.
I import the RAW files from the CF card directly (DNG and save) into LR, add keywords, organize, etc.
However, I am now at the point where I need to determine a sensible workflow that includes these steps:
Import RAW into LR as DNG.
Edit, as needed, in PS.
Apply RAW Presharpening (as provided in Nik Sharpener).
Manage Noise (with Nik Dfine (2.0 available in next 24 hours).
Apply usage-based sharpening prior to printing or saving final file version.
Maintain organization in LR.
My original plan was:
1. Import RAW in LR.
2. Open in PS.
3. Apply noise reduction.
4. Apply RAW presharpening.
5. Save (with new version being an "Edit" copy back in LR.
6. Maintain organization in LR.
I'm wondering, though, if I wouldn't be better off doing the basics to the files prior to LR import. Note that the Nik tools work in 16-bit mode.
This is theoretically what I'm thinking, and would appreciate other user's input:
1. Save RAW files to location on Mac.
2. Apply Noise reduction to RAW files with Nik software within PS (perhaps automated, perhaps batched).
3. Apply RAW presharpening to RAW files with Nik software within PS (perhaps automated, perhaps batched).
4. Import noise- and presharpening-adjusted files into LR, with metadata additions, etc.
5. Open files in PS as needed, with files becoming edit versions within LR.
Any thoughts?

To summarize, then:
First time opening a RAW file from Lightroom, LR automatically creates a copy and appends "-Edit" to the filename. If it's a RAW file, only available option is the third option in the dialog box: "Edit a Copy with Lightroom Adjustments."
Once opened in Photoshop, any number of adjustments can be made and saved. All adjustments are reflected in the -Edit copy when previewed in back in LR.
If, later, I want to perform further PS edits on the -Edit version, I have 3 options as presented in the dialog box.
1. "Edit Original (LR adjustments will not be visible)"
2. "Edit a Copy (LR adjustments will not be visible)"
3. "Edit a Copy with Lightroom Adjustments"
Option 1 will open -Edit version #1 (but it will not show any changes made in LR to the -Edit file when opened in PS)
Option 2 will create a copy of -Edit version #1 and open that new file, -Edit-2 (but it will not contain any changes made in LR to the -Edit file)
Option 3 will create a copy of -Edit version #1 and open that new file, -Edit-2 and it will contain any changes made in LR to the -Edit file
So, a typical workflow would be:
1. Import RAW file in LR.
2. Make adjustments in LR.
3. If needed, open a copy (by default) in PS via LR (command-E).
4. Adjust in PS, save.
5. Adjusted file is stacked with original RAW file in LR.
6A. Assuming no additional edits in LR, further PS adjustments can be made to -Edit version original, keeping just 1 stacked version in LR.
6B. If additional adjustments are made to the saved -Edit version in LR, and further PS adjustments are needed, I must edit a copy of the -Edit file, ultimately resulting in a second stacked file.

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.

"noise reduction" not applied to exported photos

I've always used iPhoto to slightly modify my photos, before exporting and sharing or uploading to Flickr.
But, since yesterday, the exported photos do not include my "Reduce Noise" modifications. When I export them, they include the color, retouch and so on, but they look as they were BEFORE I applied the "Reduce Noise" filter.
When I look at them in the browser, they appear WITHOUT noise reduction.
When I press space to see them zoomed, they appear WITHOUT noise reduction.
When I double-clic to switch to edit mode, they appear WITH noise reduction.
And when I export them (either by dragging and dropping to the desktop or an application, using the export function or opening in an external editor), they appear WITHOUT noise reduction.
I have tried to delete the preferences of iPhoto, but the behaviour of iPhoto remains the same.
This applies to all the photos I've tried it onto. And this never happened before yesterday.
I didn't install anything new, I have no plug-ins or things like that. I've repaired the permissions, even restarted and zapped the PRAM. The only thing I've done recently is install Aperture with the 30 days trial offer. Could this be the origin of the problem?
iPhoto is an important tool for me and has always worked perfectly. I hope someone will help me solve what is a big problem for me.

I sent to the trash the iPhoto preferences I could find and launched it again
This time, I got the same behaviour, but also got console messages, as follows:

Noise reduction (audio) doesn't seem to work - what am I missing?

Hi,
In a clip that I'd really like to use, there is a pervasive buzzing hum throughout, especially noticeable in long shots where there isn't any competing or overriding sound.
I've read the instructions in the manual for taking and saving a noise print of the noise itself (there is a perfect segment in the clip to use for this), and for applying it to the entire clip by Selecting All and going to Process>Noise Reduction>Reduce Noise, then applying the saved Preset. Also watched the video, which gave exactly the same directions. The Noise Reduction line appears in the Actions tab underneath the clip name, and it looks like it's processed, but when I bring the HUD up and hit the Play button, nothing has been removed. The offending sound is still there.
If I click on the Noise Only box in the HUD, there is no sound at all, which seems to indicate that Noise Reduction hasn't actually been applied.
I've deleted the file from Finder and started from scratch twice, but still can't get it to work.
Obviously the Noise Reduction can't just "not work" - so as a new user of Soundtrack (3.0.1), what have I not understood?
Thanks,
Marg

When you get to Process > Noise Reduction > Reduce Noise, usually a preset isn't the answer, but some manual fiddling.
Here's the way I approach this:
1. When I set the noise print, I play/loop the clip and note the level of the noise in your meters. When I get to the threshold in the noise reduction window, that level will be the extreme highest threshold I use, only going lower from there.
2. When it comes to the reduction, I check the Noise only box while I'm setting it, and boost the reduction until I'm getting noise, but not too much signal I want to preserve. If I hear voice in there, I'm doing too much. And I rarely end up going beyond 60%.
3. Uncheck the noise only box, and listen to the signal with noise reduced to fine tune further.
Remember this is noise reduction, not noise elimination. And, the STP tool is pretty good for what it is, but it's not anywhere near the best out there.
Good luck, and I hope this helps!
Matt
