[darktable-dev] Noise reduction

[Jan Ingwer Baer]

Are there any plans to add additional NR algorithms like KREMY
(http://aggregate.org/DIT/KREMY/) to DT?

[darktable-dev] Noise Profile

[Andreas Schneider]

Hi,

I'm still looking how to simplify the process for creating noise profiles. So 
I did a new experiment today.

However nobody really explained the plots to me. Could someone do that?

New test setup:

https://discuss.pixls.us/t/fujifilm-x-t3-support-tracking-discussion/9243/15?
u=asn

I just quickly shot the images so I was not very careful. Some could be a bit 
darker which produces a better result. I just want do know it this works. 
However nobody explained the plots and what to look at yet, so I have no idea 
and an explanation would be great.

Results:

New feature (filters stack widget) to rearrange filters, pin filter to
apply changes in place where it was initiated :)

 Pay attention to history and NR tool clarity.
 DT may replace all denoise tools with just a huge list of denoise
 profiles. We will try to apply one by one untill good enough result.

if you have followed the UI refactoring discussion lately then you will
have noticed that the intended target audience for DT are programmers
and graphics nerds who really know what each module does, [...]


Rolf nails the issue.

The basic problem this discussion is about is UX created by developers.
Developers usually understand well what an algorithm can do. Let's call 
it the 'domain of possibility'.
Users commonly only need a tiny subset of this domain. One that lets 
them converge /as fast as possible/ to /optimal/ results for the task at 
hand by manipulating the /least/ number of parameters.


Note that with every parameter on must manipulate to get to an optimal 
result, the domain the user has to understand greatly increases. You are 
basically adding a dimension (!) to the parameter vector that governs 
the result.


Most developers, if they can't decide how to map any of an algorithm's 
parameter automatically, to govern an optimal result, will just expose 
that parameter in the UI.
You can look at this from two sides: laziness/ineptitude/reluctance to 
understand what problem the algorithm will solve for the user (vs the 
full domain of problems it can solve) or just giving 'more power' to the 
user because you shouldn't 'assume' what subset of the domain they 
actually need.
The latter is commonly the excuse developers will give but from my own 
experience the main reason is ineptitude. It's just the difference 
between how an artist's/user's brain is wired vs a developer's.


This is the single most common reason UX/UIs of software often suck(s): 
developer's don't understand that users want /less/ parameters.

They naturally think that more power is good thing.

That's why today UX has become a profession. UX people are commonly 
those that are technical enough to understand the domain and at the same 
time the results most users look for. They can map it to the needs of 
the user by producing a minimal UI that is abstracted away from the 
original algorithm.


As DT's main user group are developers or at least people with much 
better than average understanding of the underlying algorithms this is 
not such an issue.


See the screenshot of OP from RawTherapee. There is a single drop-down 
that disables the whole obscure set of parameters driving it's noise 
reduction algorithm and switches it to a mode where it chooses good 
parameters for the user. Aka: RawTherapee's noise reduction module seems 
to have a mode where it has /zero/ parameters the user must adjust, from 
the looks of it!!! Amazing, if this is true.


This would be top notch UX. DT lacks this. By design. Whether this a is 
a good or bad thing is a different discussion.


I have my own opinion about this. I urge interested parties to watch a 
talk on how developers make artists lives harder and how some companies 
(the speaker works for one) are trying to abandoning this practice.


https://www.youtube.com/watch?v=-ihVkVqCOGc=youtu.be=287

This part of the talk made a lot of waves in the VFX world. The number 
of mails the speaker (a friend of mine) got form renowned industry 
professionals, seconding his findings, is overwhelming.


This talk also contained a section where the speaker analyses how bad 
Autodesk Maya's UX is. It was cut by the sponsor, Foundry, because of 
their business ties with Autodesk.

Re: [darktable-dev] noise

[William Ferguson]

I like the last photo.  I think that really captures the essence of
darktable.  :-)

I stopped at the denoise and didn't really set out to finish processing the
image, so the colors on the bear aren't the same.  However, the detail is
still there and wasn't affected by the denoising.  I did blow the
highlights a little while I was processing and didn't bring them back in.

I actually used fewer denoising modules and less denoising to achieve a
better result.  The key to denoising in darktable, is making sure that the
image is ready to denoise.  If you apply the basecurve, which happens
automatically, it amplifies the noise tremendously.  When you try and
denoise, you then end up with the rainbow effects.  I ran DPP, RT, and DT
all at the same time.  I then adjusted DT's image (histogram) until it was
similar to RT.  I then applied the gamma curve from DPP to both of them.
At that point there wasn't a lot of noise in the RT or DT image, so
denoisiing them became a simple process.  I actually denoised DT's image
quicker because I only used 3 modules and 2 blending modes.  It took longer
to work my way through RT's sliders and drop downs. :-)

Re: [darktable-dev] noise

[Jan Ingwer Baer]

After reading all the posts in this thread i want send my own view to 
this. RT and DT are both great tools with different pros and cons. The 
most important points for me are:


RT is much simpler to use and the denoise-modul gives great results 
without hour-long parameter tweaking or years of learning.


DT has the great parametric masks feature

I hope someone will do the porting of the RT-denoise to DT. Together 
with the RAW-denoise and the profiled-denoise it will be (for me) the 
perfect way to remove noise.

I have to spend senconds with Canon DPP to suppress noise on high-iso
image,
I need minutes to get a good result in RawThrerapee, but nobody can spend
hours
to make bad result with tons of noise reduction tools. Please, break the
last barrier to DT :`|
Here my example:

rawtherapee:
https://drive.google.com/open?id=0Bz9fwFLCJOjNNnZWNjVSYXhaX28

The best efforts In general lead to green noise on barbells. It's too
complex problem for regular photographer.

Re: [darktable-dev] noise

[Rolf Meyerhoff]

Hi,

I'm a programmer, graphics nerd and photographer so DT fits me very
well. :-)

I really like to have all the power of DT available when I need it.
Recently I had to edit over 1500 scans of very degenerated photos from
the 70s and DT did a fantastic job that no other raw converter could
have done, commercial or not. When I see a technically crappy image then
I know that if DT can not recover it then no application will.

At the same time it really annoys me that I also have to use the entire
arsenal of DT to perform basic actions that are simple one slider
operations with great results in most other converters (noise reduction,
clarity, shadow/highlight recovery etc). I don't need dramatic
adjustments for my vacation photos, I need a fast workflow to get the
images ready for display (and to have time to take new photos ;-) ).
Presets really never worked for me.

That's why I proposed the basic/meta page a while ago - simple shortcuts
for fast every day editing jobs while still having all the power at hand
when it is really needed.

Greetings,

Rolf

Thank you for the detailed answer. It is worth placing on DT's main page.

Re: [darktable-dev] noise

[Maurizio Paglia]

Hi Rolf,
I am not a programmer nor a graphic nerd. I simply take potographs in my
spare time.

I like dt because I know I have in my hands a powerful tool.
No matter if I use it 100% or 10%
I know dt is SO powerful thereby I have a large margin for improvement.
Moreover I feel curious and I like to learn things...

>From a photographer point of view: every raw developer software or
manipulation software are too much complicated.
A  GOOD photography is made with light+emotions (NOT technique!).
Many times I read questions about subtle operations on photographs that are
more or less useless but people should always remember that a poor image
with a very good post-production will remain a poor image (but with nice
colours! :-).
People should focus on the goodness of the image.
So, choose the software that is more comfortable for you and go ahead with
it!
Learn some operations you feel comfortable with and try to learn how to do
them better (but do not study too much... go outside and take photographs).

Have a nice evening!
Maurizio

Re: [darktable-dev] noise

[Rolf Meyerhoff]

Hi,

if you have followed the UI refactoring discussion lately then you will
have noticed that the intended target audience for DT are programmers
and graphics nerds who really know what each module does, in which order
the modules have to be edited, how the modules interact with each other,
when to use wavelets, how to add masks and blending modes and so on. DT
is not intended to be used by novices and casual users who just want
nice looking images.

However, look at it from the positive side: If you at some point got a
result that is actually on par with the competition's two slider
solutions then you have learned a lot about the deep internals of image
processing, camera curves, color spaces, blending modes, masks,
demosaicing, wavelets and so on. Maybe you will at some point encounter
an image that needs more treatment than the typical two slider solutions
can handle and then you know what to do.

When I really have to denoise an image in DT then I use a five stage
process. First I use the raw denoise with a fairly low level to remove a
bit of noise prior to the demosaicing. The demosaicing itself affects
the shape of the noise in later stages so editing this is crucial for me
(at least with Fuji X-Trans). After the demosaicing I use two profile
denoisers, one for chroma and one for luma, again with fairly low
levels, optimized blending settings and dark area masks.

Later when I have done my exposure work I use the equalizer to get rid
of the remaining noise (again with mask). Finally I play with the levels
and masks of all these stages to get the best result. Sometimes I add a
tiny bit of grain and/or dithering at the end to smooth out the
processing artifacts and to make the result visually more pleasing.

I know that seems a lot of work but at least this gets me really close
to the result that I can achieve with the free CaptureOne version that
came with my camera. I don't need denoising very often as my camera has
fairly good high Iso capabilities and a nice grain pattern to the noise.
So noise is not that big of a problem for me (at least it's not big
enough to reboot to Windows just for denoising).

Re: [darktable-dev] noise

[johannes hanika]

..that old picture again? it has a ton of noise in green. fwiw i like
what i can do in dt better than the fine grained noise that stays in
the OP's RT version. but as pascal pointed out, it seems to be a waste
of time to comment on this here. noise preferences are very
subjective, and yes, by all means, if DPP works for you please use it!

if you want a similar result from dt you can probably create a
style/preset so it would be fast to apply it to other images in the
future. if you convince enough people that this is a useful preset for
many, we can also ship such a thing with vanilla dt.

to answer one of the original questions: it's relatively straight
forward to port rawtherapee code to our source tree. our pipeline
needs a bit more functionality (preview and scaled regions of interest
and such). RT's devs are a friendly bunch and very helpful in case
anyone wants to try this. we've done it before.

cheers,
 jo

Re: [darktable-dev] noise

[Andrey]

I like DT. I've spent a lot of time exploring related materials, trying to
get most of nr. I prepared a demonstrative picture and asked people to
teach me (time to time - forums and irc channel - last 2 years). Yes, I
keep using DPP. What is the point of my last try here you think?! To sit on
a mode? To wave a flag? If DT were a crap, we wouldn't talk here. I point
out the problem - you point out my thoughts and mode I sit on. What is
wrong? You say, that we have a great power with DT. Teach people to get a
best result (not 10x longer and 2x worse than RT), accept a problem or just
say me (and others like me) to get off. This is simple. Right now the only
result I expected was to understand what is my problem - me or DT. If it
was me, then someone can explain the way to get a good result.

Hi,

with RT or DPP. With all of it's power and all of competitors' 2-slider
weakness.

I believe it's quite good:
https://drive.google.com/file/d/1BSQA2Q49RwLVcs9TzB8v79ROW-vR-V4n/view?usp=sharing

(also a few seconds, because I've preset for this. 2 profiled denoise
instances - one for color, one for luma + defringe to reduce green halos).

Agree, I don't believe it's target for DT.

Re: [darktable-dev] noise

[Oskar Maier]

Hello Andrey,

why do you discuss this on the dev mailing list? Is this supposed to be a
bug report or a feature request? Than put it in the appropriate place (but
with a proper description of the bug/desire feature).
To me it looks more like something for the play raw sub forum (
https://discuss.pixls.us/tags/play_raw).


Cheers,
Oskar

That was 2-second tune which is very good - full of details and do not have
color noise.
Here is 4-seconds tune:

The issue with darktable is that nobody can make the image as clear, as
with RT or DPP.
With all of it's power and all of competitors' 2-slider weakness.
The issue is that a mom takes a bunch of shots from school performance
(indoor) and can do nothing with it by means of DT.
But she has zero problems with DPP. And she needs just a small demo to do
the job in RT.
I get your idea. Just waned to clarify. Thanks again.

Andrey

Hi Andrey,

Sorry guys - nobody showed me the power of dt yet.
> Thanks. Sorry for disturbance. Good luck.

Your messages sound like nothing will make you change your mind. You're set
on a mode where you think dt is a crap at denoising images.  So no problem.
Keep using DPP is this fits your needs best nobody ask you to use darktable.

Re: [darktable-dev] noise

[Sturm Flut]

Hi,

ignoring that this is one of the cases where not setting the camera to
"Auto" would have resulted in a much better picture and avoided most of
the issue to begin with:

Profiled Denoise in Wavelet mode with strength 0.2 already looks pretty
identical to what DPP does, at least to me. XMP is attached.

The output from RawTherapee looks oversharpened. Maybe that's your
issues with Dartktable as well? If there's noise in the picture it is
usually better to fine-tune using the Equalizer instead, and/or use
masks to sharpen areas selectively.

kind regards,
Simon

 One could expect super quality from these tons of sliders, switches and
 so on. But we can't get it work like single tool in RT or DPP.
 Rule of thumb: *do not* process noisy image with darktable.
 Could DT just borrow denoise tool from RT? It's very clear, simple and
 makes a great result.

Re: [darktable-dev] noise

[Maurizio Paglia]

Ciao Andrey,
believe me: I understand your frustration but I can assure dt can give you
optimal results with no pain.
Its GUI can intimidate many users because it is "Linux style" (RT imitate
LR so it is more friendly to many people) but you cannot have power with a
'single slider' interface...
Moreover you can find on https://dtstyle.net/ a lot of presets that can
help you to reach a particular result but also can help you to understand
how modules and sliders work.
It is understood you can choose to use the raw developer you prefer, and it
is understood dt needs a little more time with study and trials.
Have a nice day,
Maurizio

I have read the manual. Please, read the whole discussion and try to
process the image with RT close enough to DPP or RT.
Note the time and compare results side by side.
Thank you.

Re: [darktable-dev] noise

[Matej Martinovic]

I haven't read the whole discussion, but have you read the manual? If not, 
please read "3.4.4.3. Denoise – profiled" in 
https://www.darktable.org/usermanual/en/correction_group.html

All you "need" are two instances. Both can be saved as presets to be 
automatically applied.

Re: [darktable-dev] noise

[Andrey]

I did tried some authored presets found somewhere on the web. And I am
still on windows with dpp.
You see.. this is not a photographer workflow. DT is some kind of technical
toy.
I wouldn't try to explain denoise tools logic of DT to my wife who got into
photography. This is the main problem.
And final point is that all this magic gives the worst result for huge loss
of time. And headshot: most of
DT users do not understand what exactly they are doing with these denoise
tools.
Wavelets, parametric mask, patch size, combine mask, clone action, try to
play with those 25 combos and channels on every copy,
search for another denoise profile and tune it... are you serious?!

 Pay attention to history and NR tool clarity.
 DT may replace all denoise tools with just a huge list of denoise
 profiles. We will try to apply one by one untill good enough result.

Re: [darktable-dev] noise

[Maurizio Paglia]

Hi,
just for the record, did you tried to use some presets?
I understand dt can appear difficult, so you can try to apply a preset and
then - if needed - only adjust some sliders.

Tanks,
Maurizio

Re: [darktable-dev] noise

[Andrey]

I like your work. We have got a nice bench, lever is ok, but the bear..
darktable vs dpp:
https://drive.google.com/open?id=1G026G5va8h-V8Mqn0HlghslN7vKnfvwG
darktable vs rawtherapee:
https://drive.google.com/open?id=15hxaZDOh0Cqrs3IptcEdH_kPjSuu-NR9
I've tried to recover the bear, but my result is still far from competitors
(shadows are awful too).
Don't you see it's too complex for regular users? I've tried to combine
several denoise tools with no luck (unlike you).
We both spent too much time with single image doing something on a hunch.
https://drive.google.com/open?id=1xWAXmF2_I7BD2XnLgGABoQMMf3ATDBC4
One could expect super quality from these tons of sliders, switches and so
on. But we can't get it work like single tool in RT or DPP.
Rule of thumb: *do not* process noisy image with darktable.
Could DT just borrow denoise tool from RT? It's very clear, simple and
makes a great result.

Re: [darktable-dev] noise

[William Ferguson]

I loaded DPP and played with the image to see how Canon processed it.
Then, I went back to darktable and tried again.

Here's what I came up with.

Re: [darktable-dev] noise

[Andrey]

Just compare the pictures side by side. Your result is rather good for DT,
not for RT or Canon DPP.
Stains, colored lever, bear's fur is blured.
Look at this:
https://drive.google.com/open?id=1_s1WzY2D_fgxTs0sjP4ygsPUcnf_GfkA
Pay attention to history and NR tool clarity.
DT may replace all denoise tools with just a huge list of denoise profiles.
We will try to apply one by one untill good enough result.

[darktable-dev] Noise profile for Nikon D850

[Neil Schemenauer]

Hello,

There doesn't seem to be a noise profile for the D850 in Darktable
yet.  I followed the instructions on the "profiling sensor and
photon noise" page.  The scripts warned me about the images not
being under-exposed.  However, I exposed at EV compensation -1.0 and
used the highest contrast scene I could devise.  The curves look
reasonable I think and I've tested them on some of my photos.  The
result looks good to me, unlike the generic profile (much too
strong).

http://arctrix.com/nas/tmp/dt-noiseprofile-20171229.tar.gz

  Neil

Re: [darktable-dev] Noise profile Sony ILCE-7RM3

[Bob Tregilus]

Done!

And thank you Stefan! :)

And Pete, yes, I had found your blog at  https://landscrapes.wordpress.
com/2016/05/10/darktable/ regarding sensor profiling.

Oops, now that I look at it, I take that back, I hadn't seen yours.

Thanks, I'll review it. I'd really like to work through this process for
myself even though Stefan was able to create a profile for the ILCE-7RM3
using my image set.

But first I have to get stupid Windows running again on my laptop so I can
use the Adobe DNG Converter and flash the firmware as necessary on my
cameras. All I wanted to do was change the hard drive. What a headache, but
that's not of interest to this group.

The Darktable community rocks!

Cheers,
Bob

Re: [darktable-dev] Noise profile Sony ILCE-7RM3

[Pete Hall]

I wrote up the process I used for a Canon G3 X. Maybe that can help you get 
started. https://landscrapes.wordpress.com/2016/05/10/darktable/

My process may not produce enough midtone. I got around that when I did my T7i 
by draping a cable through the frame from top to bottom. With everything 
defocused nicely, that seemed to give me plenty of midtone.

Regards,
Pete

[darktable-dev] Noise profile Sony ILCE-7RM3

[Bob Tregilus]

Hi -

I've been muddling around attempting to create a noise profile for the new
Sony ILCE-7RM3.

Sadly, I'm just a user and I'm still trying to figure out how to add "raw
linear.dtstyle" to DT so I can apply the style to the ISO image set I
created.

Additionally, since the ILCE-7RM3 is not yet supported in DT--but will be
in version 2.4.0 thanks to Adam and Roman (fix #11848)--I'm guessing I need
to convert the camera RAW to DNG files using the recently updated Adobe DNG
converter.

The problem there is I was upgrading the hard drive in my laptop with
Windows 7 and the system restore plus an ISO image backup are both failing
to install correctly (apparently, something to do with MS licensing issues
and Win 7 thinking I'm installing it on a different computer).

Anyway, just in case one of you wonderful developers has nothing to do in
the coming days (***laugh***), and you have the time to generate the noise
profile, I went ahead and uploaded my ISO image set from the Sony ILCE-7RM3
to my Dropbox at: https://www.dropbox.com/s/wz6ixpfvkupnrfc/Public.tar.gz

The tarball contains one image from each ISO setting, plus three images
from ISO 100.

In the meantime, I'll keep trying to figure out how to do the noise profile
myself. It's just going to take some time. I'm really slow at this stuff if
the instructions aren't ultra basic how-to-boil-water cookbook style.

Thanks--again--so much--for such an awesome program!

I'm really looking forward to the release of 2.4.0!

Bob

Best to open a new issue in redmine, less chance of this being lost.

Hi,

There was a bug in darktable < 2.2.0rc1 that effected noise profiling.
Please rerun the script with an up to date version.

[darktable-dev] Noise Profiles for Panasonic DMC G7/G70

[Joerg Hunger]

Hi,

I have created noise profiles for the Panasonic Lumix DMC G7/G70 and
uploaded the resulting tar achive to:

https://www.dropbox.com/s/zafgi8viiyqimyv/dt-noiseprofile-20160704.tar.gz?dl=0

This camera is labeled with two names by Panasonic: G70 in Germany, Swiss,
Austria and G7 everywhere else.
So presets.json contains the two identical profiles with different model 
names.

Please include these noise profiles into the next darktable release.

Regards
   Joerg

[darktable-dev] Noise profile for Canon Powershot G3 X

[Pete Hall]

Noise profile for Canon Powershot G3 X

This still hasn't been added to the distribution. I notified this list
at the beginning of May, and it apparently fell through a crack or
something. Would someone please validate and add this to the product or
let me know if there's a problem with it?

https://www.dropbox.com/s/spuxu4jkejhu4dl/dt-noiseprofile-20160503.tar.gz?dl=0

Please let me know when you've downloaded this archive so I can remove
it from dropbox.

Thanks

[darktable-dev] Noise profile for Sony A7II

[François Tissandier]

Hello !

Just arriving on this mailing list, I would like to help for the camera
support in Darktable.

First, with the noise profile of the A7II. I'm seeing this page, but I
don't know if it's up to date :

http://www.darktable.org/2012/12/profiling-sensor-and-photon-noise/

So my questions :

-is this page up to date ?
-if it is, should I download Darktable from the git repo ? I don't see the
"gen-profile" application on my computer (I'm using the unstable 2.0
version from the PPA)


Also, I noticed weird colors on the RAWs from my A6000. I have submitted
this issue :

http://redmine.darktable.org/issues/10781

I hope it's the right way to do it ! Please advise if I did it wrong.


 François

[darktable-dev] Noise profiles

[Stein Jakob Nordbø]

Hi,

I've tried to generate noise profiles for my Olympus OM-D E-M5 mk2:
https://www.dropbox.com/s/50pvcexey23v1i7/dt-noiseprofile-20151008.tar.gz?dl=0

The command that I ran and its output is available here:
https://www.dropbox.com/s/bhss1a5hlbjfgbp/output.txt?dl=0

Let me know if I can improve on these profiles in any way, or if you want
to get the ORF's. Also, feel free to request other kinds of calibration
data if there's anything I can do to improve support for this camera.

One thing that was a bit unclear to me in the blog post at
http://www.darktable.org/2012/12/profiling-sensor-and-photon-noise/ and the
help output from the gen-profile script: Is it necessary to import the raw
files into darktable first, apply a style, and then export and run
gen-profile on those images (if so, what's the preferred export format - a
lossless one, for sure), OR is it sufficient to run gen-profile in the
directory containing the raw files (as I did), trusting the script to apply
the correct styles on the fly (I observe that the extracted thumbnails look
identical to the JPG's saved by the camera, ie a simple extraction from the
raw)?


All the best,

Stein Jakob Nordbø
