I agree that I could get the look I want by tweaking the camera settings.
What I meant here with 'default' was 'the default DT gives me'.

And the in-camera processing is what most people use in practice. But those 
are not the users you find here (almost by definition, as DT is a RAW 
processor...).

Same thing, most people shoot jpeg only (is there any phone that produces RAW 
images?). They don't need more, and don't want more. Nothing wrong with that.
But that's not a reason for *me* to limit myself to what the camera is willing 
to produce. I prefer getting the best possible exposure in camera, and then 
get the image I want while working on a decently sized screen, with better 
tools than a camera can give me

Also, you took my reply out of it's context, which was a question about how to 
get the same image as the camera delivered. I just pointed out that, while 
reproducing the in-camera image might be a good starting point, it's not the 
aim of using RAW format, so he should not limit himself to that or get too 
fixated on that.

  I expect to always shoot in RAW for two reasons, no matter how good and
tweakable the JPEG processing in cameras get.

  First, shooting in RAW means that I don't have to try to judge the
picture's colour and tonality from the little LCD on the back of the
camera while I'm out in the field. Plenty of painful experience has
shown me that I am fairly bad at this, in both directions even with
just camera JPEGs (pictures that look fine or even great rendered on
the LCD look bad on the computer, and 'wrong' pictures can look fine on
the computer). Since RAW can change both tonality and colours after the
fact without much problems, I can mostly get away with just checking the
histogram.

(Since I not infrequently shift white balance for artistic effect,
getting the colours right isn't just as simple as 'take a white balance
shot off a grey card beforehand'. Accurate WB gives me 'correct' JPEG
colours, but not necessarily the colours that I want.)

  Second, I'm increasingly using Darktable to make selective alterations
to only some areas of the picture to do things like bring up shadows or
tame highlights. Even if cameras become technically capable of doing
this, I don't want to try to set it up and do it through the little back
of camera LCD and the limited control interface a camera necessarily is
restricted to.

  In theory I believe you can do all these sorts of alterations on
JPEGs after the fact, not just RAWs. However, my understanding is
that RAWs give you far more latitude to do things without creating
visible artifacts like posterization. And in practice, photo
processing programs today and probably in the future are far more
willing to do these sort of changes with RAWs than with JPEGs.

  Even if I could reliably 'get it right' in the camera and know that I'd
done so, I sometimes change my mind about how best to realize a picture
once I'm staring at it on my computer. The on the spot idea I had in my
head when I took the picture is not always right or the best option.
Sometimes there's a better option (and sometimes the photo turns out to
be a writeoff, and no amount of tweaking its development will help).
Good points I also switched to all RAW. For a period of time I was 
shooting both JPG and RAW. Then when I compared the results (and my 
corrections are quite basic... I moved to RAW only. I don't even try to 
match JPG any more.

B

While I can understand and still mostly favor myself the use of raw files, I 
cannot understand the use of "default jpeg". Why use "default" settings 
while there are so many possibilities to tweak the image in camera ?

As an "amateur" photographer for 55 years, I always have seen, first with 
"labo", to day with software, processing as mostly desperate attempts to 
remedy bad exposure... So the in camera process would be for most people the 
best choice...

In this meaning, and based on what I see on Flickr, Ipernity and others I'm 
conviced that one day I'll probably shoot 90% jpeg, which nevertheless can 
be sufficently (for my taste) tweaked in Darktable and Bros. Most people 
won't ever never see the difference when printed or on screen size.

I post rarely here so I have to say at least once how I an thankfull to the 
devellopers and maintainers of Darktable.

I also apologize for my froggish english... ;-)
