Leica M9 and Aperture 3 (especially noise reduction)?

As Aperture 3 still does not officially support the RAW files of the Leica M9 I would like to know if someone has found a good way to reduce the noise of M9 pictures that have been shot with high ISO (1250 and above). I find the noise reduction of Aperture 3 quite disappointing. Do you use a third party application for that?

Try Noise Ninja. I am using it for some time now, with good results, although i am not owning a Leica M9. There is an Aperture plugin that works quite well.

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!

Newbie question about vinyl noise reduction

Dear folks,
I am entirely new to Audition (trying out the Mac beta), so if this question is entirely answered by other threads, please just point me in the right direction. Thanks!
I am transcribing all my vinyl albums (48KHz, 32 bit) as FLAC files and now I need to clean up the transcriptions. Both DeClicker and Noise Reduction (process) seem to do an excellent job at the default settings for each, but I am not sure of the best way to use them--
First, which order is it best to use them in; DeClicker first or Noise Reduction first?
Second, are the default settings ( threshold :30 and complexity:16 forDeClicker and 100%/40dB for Noise Reduction ) the best ones to be using in general? If not, what qualities, audible or otherwise should I be looking/listening forto help me figure out the best settings to use?
Third, any recommendations for help files or tutorials I should read on this subject?
Thanks for your help!

If I understand you correctly, you're recommending two passes with the Noise reduction process-- one with a large FFT followed by one with a smaller FFT sample size, right? The default for the process is a 4K sample window, with windows from 0.5K to 16K available. What values would you recommend for the two passes, and what NR percentages and dB "reduce by's" would you recommend for each pass.
Yes you understand correctly, but it's rather difficult to say how much to use in any given situation, because it depends entirely on the condition of the original recording. The basic rule is 'as little as you can to achieve an acceptable result', whatever FFT size you are using. As for sizes, the 4k is fine for the LF pass (you might want to look at adjusting the blue line to shape it so that it only attacks the bass, as well) and 16k is fine for everything else.
In some ways it's easier to talk about what is a realistic end result to achieve, than actual reduction numbers. Realistically, you should be able to get vinyl noise floors down to around minus 60-65dB, assuming that your signals get close to 0dB peaks. But with some older records, you may well not get this far before things start to sound rather 'fake' because you've over-processed the results. Often it's better to monitor the results on a pair of headphones rather than speakers - you'll hear more low-level detail, and have a better idea of how much processing you can get away with.
Yes, RX2 is pretty damn good - as good as you can get, in fact. But for vinyl, with care you can definitely get good results with Audition, but it takes more effort, especially with the NR. What actually makes RX2 good is that the multiple pass part of the processing is done for you by the software, and that's the major difference - other than that, the basic algorithms are quite similar. But, it costs an arm and a leg, so unless you have a massive amount to do, or somebody's paying you to do this, it's a dubious investment.

Rauschen - Noise reduction - Denoise

I need to reduce noise on my photos, but it does not work with PS Touch even if the option is there! I have moved the slider from 0 to 100. It tried with another app that is adobe ps express, and it worked well.

I have the same exact issue!
I've tried re-installing and rebooting the phone. I literally bought the app to make my skin look sexy and smooth with the noise-reduction! But it's not working! Please help my skin look good!

Recovery connected to noise reduction rendering

Just noticed when I crank the recovery slider up (ACR 4.4 Profile), Lightroom stops rendering fit view with color noise reduction applied when I get to 55 in the develop module. i.e. at recovery of 55 and greater, no color noise reduction is applied, 54 and below, color noise reduction is applied.
Not sure what to say about it - just an interesting observation for the hyper-inquisitive...
R

Yeah, it does tend to dull a photo, however with ACR 4.4 (a linear profile) it can be cranked all the way to 100 without screwing up the hues, and I often crank it all the way up as a test and then lower to taste... - that's when I noticed the unexpected connection with the color noise reduction.
PS - I sometimes use recovery to recover highlights (and dim the light tones as side effect), then use the tone curve to brighten the light tones back up.
Summary:
- With ACR 4.4, I feel free to use recovery 0-100 - often in conjunction with the tone curve to compensate for side-effect repression of non-highlight tones. With non-linear profiles, I strive for highlight-recovery=0 in most photos, due to unfavorable hue shifting.
- For some reason, Highlight Recovery amount is affecting Lightroom's decision about whether to render color NR in the fit view.

Color Noise reduction with BxW

Just wanted to share what I have seen so far with this:
I sometimes use extreme HSL shifts with BxW images to achieve the tonal separation that I am looking for. This can lead to splotchyness, if taken toooo far. I just installed 1.4.1 and tried the color noise reduction filter for this (it was my most desired feature in the 1.4 update)
As of 5 minutes of playing with it I can say it works. It is not perfect, and it does cause a very slight softening of detail (very slight) But it definitely does help to remove a good bit of the aforementioned splotches.

Maybe this is snobbish, if so I apologize. I know that topics go off base sometimes...but this conversation has nothing to do with the topic I started. It should really have been it's own topic (for more than one reason. Maybe others need the info about slide shows, but would not look at this due to it's title).
Except for being about noise reduction it has nothing to do with what I wanted to hear other users comment on: The use of the color noise reduction slider with BxW images in 1.4.1
Again sorry if this is rude of me. I don't belong to too many forums and really don't know what the proper etiquette is here.

Noise reduction before or after enlarging ?

Hi. I'd be interested in your opinion:
If the circumstances force me to work on images with noise which have to be enlarged, and if I use noise reduction based on noise-pattern-recognition, is it better to carry out the noise reduction before or after the enlargement (and in case the answer is after, which resampling method would resample the image (and thus the noise) best for subsequent noise reduction?)
And what's the logical rationale behind the answer ?
Thanks a lot!
PS: I think the answer will be the same for any type of noise, but if there are significant differences between noise types, I'd be interested in that, too.

Thanks for all your comments.
I also thought that NR should be applied as soon as possible, leaving the noise patterns intact. On the other hand I thought that enlarging also enlarges residual noise, so maybe the bottom line is to do a regular NR initially and then, after enlarging, a second weak/careful one on parts of the image if need be.
@Freeagent: very good tip the inverse luminosity mask! As for ACR: From my personal experience, ACR noise reduction is very effective on RAW material, but on all other sources it far lags behind noise-pattern-recognition methods.

Noise reduction on track1 using noise print from track2

I have an audio track from a video project that was recorded on track1 that has a lot of interference from the wirelss mic that was so strong that it crossed over to the idle track2. Track1 has the voice and interference intermixed. Track2 just has the interference. How can I take a noise print from track2 and use it to reduce the corresponding noise on track1? Any ideas?

Bristol87 wrote:
In addition, to make the process more challenging, I am unable to get the audio in the edit frame to play at the same gain as in the multi-track frame. In edit mode I seem to be at a 0db gain whereas the multi-track is playing at over 12 to 20db.
I am also unclear how to get the changes back to Final Cut. When I go to File to save it I do not see a Save option that would transfer the edited audio back to the Final Cut Project.
For the additional items you mention:
1. In your multi-track project, check your volume envelopes on the track, and check the level on your submix and master. To do this, click the the disclosure triangle just left of the track name. You'll see in purple the envelopes section, which is like keyframes in FCP.
2. You have to export a mix to send it back to FCP. Go to File -> Export, save the master mix with a file name, and most likely as an aiff file, then in the dropdown "After Export" choose "Send to Final Cut Pro Sequence."
For your noise reduction questions - applying noise reduction is for broadband, sustained noise, like an air conditioner or a hum. Are you trying to apply the same noise reduction to several files because they have the same type of background noise? I generally just save my settings, but set a new noise print for each file. I'll give you a quick step by step:
Select a bit in the file where there's JUST noise. Then go to Process -> Noise Reduction -> Set Noise Print. Then select the entire file, and go to Process -> Noise Reduction -> Reduce Noise. When the noise reduction window comes up, you just need to listen and play with the settings until you're satisfied with how it sounds. As a starting point, take a look at the level of the noise alone, and use that as the threshold. Usually 100% noise reduction doesn't sound good, but you just have to use some trial and error. Too much sounds worse than too little, in my opinion. When satisfied, apply it and save the preset.
Hope this helps!

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...

How to separately control color and luminescence noise reduction?

Most of the time a little bit of Chroma noise reduction is all I need. I don't want to degrade the sharpness by applying luminescence blur unless I have to. Lightroom 3 has separate sliders. Is there a way to do this in Aperture 3?

What code do you already have for changing the color and the number of elements? Whatever it is you need to somehow tie that to being able to control it with a slider. Would this be one slider to control both properties, or a different slider dedicated to each?

Noise Reduction question for Aperture

I recently purchased my first iMac (after years of being a windows user) and decided to try out Aperture (to use with Photoshop Elements 10 as an outside editor). I am basically an Olympus user and like the way Aperture handles the Olympus ORF RAW files a bit better than Lightroom (which I have used since it was released).
Anyway, I do think that Lightroom did a better job of handling/adjusting the noise in the higher ISO Olympus RAW files than Aperture - again just starting with Aperture.
2 Questions:
(1) Am I missing something or is the only Noise Reduction controls in Aperture the two sliders that come up in the Inspector column?
(2) What is a good plug in for noise reduction that works with Aperture?
Thanks, Steve

Capture NX level noise reduction in Aperture - how close can you get?

Searching the forum for NX, it seems most posters agree that Capture NX noise reduction beats Aperture.
But let's assume that I really want to use Aperture instead for my D300 NEF files - because of Aperture's better UI, catalogue abilities and all that.
Does anyone have any easy guide with steps to take in Aperture to best do noise reduction? Can one get even remotely close to what NX can achieve?
Or should one resign and use both applications in parallel?

The noise reduction facility in Aperture is basic at best. If you can be patient, we're assured that very soon there's to be a Noise Ninja plug-in for Aperture. This will do a much better job I would expect.

Why does PhotoShop CC 2014 crash my Windows 7 Professional 64-bit PC every time I try to use Sharpen/Blur Reduction and also Noise Reduction ??!!!???

Hi Adobe
You a have a really wonderful PhotoShop CC product. It's really great, and I know new versions such as 2014 have their teething problems.
But I am getting really sick of my Windows 7 Professional 64-bit PC being crashed whenever I try to use PhotoShop CC 2014 Sharpen / Blur Reduction and also Noise Reduction.
This happens both with JPG's and PSD's.
Please sort your **** out and get some patches out to address this quickly !!
Chris Tattersall

Chris,
It doesn't crash for everyone. A person could be forgiven for saying, in return, "Please sort out your **** system problems".
Trust me when I say many, many problems are caused by the computer system setup not being up to the needs of this cutting-edge graphics software. Photoshop is heavily dependent on the GPU, and GPU drivers are notorious for having bugs (they're primarily written to run games).
However, that being said, recent driver releases from both ATI and nVidia do actually work pretty well with Photoshop CC 2014.
What video card do you have?
What display driver version are you running?
If you're unsure how to tell these things, go into Photoshop, choose Help - System Info, copy the data, and post it here.

Upscaling and noise reduction in ACR

I've been thinking about upscaling images and the best time to do so (if I need to of course) in my workflow. As I understand it, it's always best to carry out any noise reduction prior to upsampling an image, as this helps avoid increasing the size of any noise that may be apparent in the image.
However, I'm thinking that in ACR, this in theory would not be neccessary as ACR would carry out any noise reduction and upsampling in a pre-defined processing order. So put simply, I could increase the image size and then carry out any NR as required after upscaling. This would allow me to tailor the NR to fit the increased image dimensions (and of course I could then carry out capture sharpening for the larger image as well).
Is my thinking correct here - does it not really matter in terms of image quality if I don't do any NR before changing the image dimensions in ACR?
M

I did a lot of experimentation with upsampling during conversion.
I found that - in my opinion - upsampling during Camera Raw operation yields superior results to doing it later. I also believe that dialing in some noise reduction during Camera Raw is needed, as even low ISO images get pretty grainy otherwise.
Every camera is different, but what I ended up saving for defaults is this, keeping in mind that I do my conversions to the largest possible image size, then downsample later for specific uses.
Only you know what your goals are and what you like in your images, so I encourage you to experiment as I did with different combinations of settings to try to find the right balance.

Base Sharpening and Noise Reduction D800/E

Has anyone set up a base sharpening and noise reduction at different ISOs for the D800/E?
I had LR all set up for my D300 and D700 so the base settings where used at import.
Now I need to do it with the D800E and was wondering what others might be using.
Thanks
Jim
