The image is a DNG out of a Pentax K-3 II, is 30MB, and available via

Thanks for your help.

Below is my attempt.  I tried Fill Light for the first time ever (to  
bring

shadow detail out), along with Tone Curve (Low Contrast to bring out the
shadows some), and some manual exposure changes.

Thanks for trying, but Google Photos won't play with my normal browser  
(Opera), and when I try with Firefox it reckons I have to have an account!

What a silly question, those are the best. ;-)

More seriously, the problem is most likely that you are looking at the images 
at 200%. Everything but 100% requires some kind of scaling, done by the image 
viewer. And most of them prefer speed over quality there, so the results will 
be different. The only way to compare images is looking at them at 100% so 
that no scaling is required at all.

Both pics are scaled up to 200% for this screenshot.
In this case I used Bildbetrachter 3.10.2 Der GNOME-Bildbetrachter, but with

What did you mean with pixel-perfect?
I can upload the files, but it is a topless picture, this is allowed here?

Left is definitely pixellated while right is smoothed.

On the left, everything is rendered with 2x2 pixel blocks.

Left looks less blurry but does not actually contain more details that 
right.


So, it's not that "JPG are blurred".

Temporary diagnostic: pictures aren't displayed 1:1 scale but they are 
scaled up 2:1, aren't they ?


What software are you using to display JPEG on the right ? Can you ask 
it to display 1:1 size (pixel-perfect) ?


On the left, are you seeing the RAW file with darkable ? Else with what 
? Can you ask it to display 1:1 size (pixel-perfect) ?


Can you share RAW and JPEG files ? It will help make a definite diagnostic.

Regard.

JPG exports are okay for me here with version 2.0.3 on Ubuntu 16.04 64-bit.

Can you be more specific and post an example online ?

Re: [darktable-user] Re-using a parametric mask

[Matthieu Moy]

The problem is that the result of application of a parametric mask is a 
high-resolution bitmap (~100 MB uncompressed). Not the kind of information you 
want to store in the database or the xmp files.

In theory, it would be possible for one module to do the "parametric mask -> 
bitmap" conversion, and to provide it to another module further in the 
pipeline, but I guess that would break darktable's architecture (one big linear 
pipeline) rather severely. So, that's the kind of feature easy to dream about, 
but much less funny to implement :-\.

[darktable-user] Re-using a parametric mask

[Jean-Luc Lacroix]

If I create a parametric mask in one module, is there a way to re-use it 
in another module?
It's possible with the drawn masks, but could not find how to do the 
same with the parametric masks.

They also do not show in the Mask Manager.

Cheers.
