Darktable has a fixed order in which the modules are applied to the image, 
independent of the order in which you activate them. So your workflow is mostly 
a matter of personal choice. The manual explains why this is the case.

The thing to keep in mind is that modules differ in processing complexity, e.g. 
"profiled denoise" or "equalizer" need quite a bit of processing power. You 
might prefer to activate those only towards the end of the editing. In 
practice, though, on a modern PC with a mid-range GPU even those modules work 
fast enough in preview mode.

About your workflow: "local contrast" is not the same as sharpening, although 
it might appear to give a crisper image. It does use the same basic algorithm 
as unsharp masking, but with a much higher radius. Both change the acutance of 
the image, with possible some loss in the smallest details. 
The equalizer module works in a completely different way, which at least in 
theory, allows to actually recover some extra detail from the image.

And, if you work in raw, you might want to use "white balance", "highlight 
correction" and "base curve". Otoh, if you work from jpegs, raw denoise isn't 
useful (but you probably wouldn't be able to activate it).

you can use the modules in any order suits your particular notion, but
they are applied in the order they appear in darkroom mode left panel,
history.  it is suggested you do the noise modules last as they will delay
your screen display the most.

[darktable-user] Work flow

[Michael]

I have determined (supposed... guessed) that these are the following
modules I need to use. Does it matter what order I use them in? (the list
is in the order I will use them) I supposed that LENS CORRECTION needs to
be one of the first since the correction changes the keystone.

- lens correction
- raw denoise
- spot removal
- rotate image
- color zones
- contrast brig...ss saturation
- shadow and hilights
- local contrast = sharpen image
- defringe

What do you think I need to add?

Meant unless you are keystoning on a square or a rectangle you will wind up
with a trapezoid. And then with quite a few of the pictures I do not have a
corner to focus on because another object is in its way. I want to be able
to line up on vertical line and then on a parallel line. Then on a
horizontal and then on one of its parallel line.

I have no idea what a "qudangle" is and google doesn't help.

my experience with keystone using usually full straightens a
rectangle/square object to appear as if viewing from directly in front.

I don't understand your problem, it appears to work correctly for me and
has for several years now.  and I use it frequently, usually to straighten
a soccer scoreboard to appear as if viewing from directly in front.

Only if you have a perfectly square object you're aspecting. Otherwise you

The 4 lines are totally independent  simply  try it

You might want to try the perspective module first and then if that is
not satisfactory the C will make the impossible possible.

Between the perspective module and the C dt has extraordinary
correction capability.

[darktable-user] full keystone

[Michael]

I think the four alignment bars should be independent of each other instead
of having them tied together. I have a picture of a house and I don't have
a perfect square, I have the side of the house, the top of the house, and
not totally square windows. Has someone already suggested this?
The archive doesn't have anything and I can't find any reference in th
manual.

Re: [darktable-user] Variables in Watermark

[Matty Gabe]

Roman has it right, the docs were correct I just wasn't aware (when I read
the docs the first time) that there's a "simple text" SVG built-in that
will respect them.

Also, the variable structure is different than with the file import/export
formats, so I tripped on that.

THANK YOU ALL FOR THE HELP! I look forward to helping others in the mailing
list :)

Aw: [darktable-user] Variables in Watermark

[Michael Fritze]

Matt,

 

I used Inkscape to add filename and timestamp. Just open the simple_text.svg, modify and/or copy the string and save to correct location. (check docs)

Works very good for me as soon as I read the docs ;-)

 

Micha.

Betreff: [darktable-user] Variables in Watermark


Hello!
 

I've been Googling and searching like crazy to find out if it's possible to use variables (like $(EXIF_MONTH) ) in the watermark so that I can add a timestamp to exported photos programatically rather easily, instead of having to do it by hand.

 

I saw the simple_text.svg option and it looks like it uses a variable behind the scenes to display the text I enter on-image, but that box is never parsed for variables I enter.

 

Was hoping someone can at least confirm if this is not possible at the moment.

 

Thanks!

 

Matt

Here's a little script I use to watermark photos after export.
