Number one for me is DT's abilty to edit. Any ability to search for and

keywords. I am not a developer so I don't understand what is easy and

Agreed.

Doing some (amateur) programming myself, I know that sorting tends to be 
costly. But filtering not as much, and SQLite is... lite and fast. So 
using tags and such as mentioned, to filter, not sort, is probably best.


As to performance.

I have "only" some 10-20k photos, I am an amateur and I don't go out 
shooting much. So it is not a problem that I often end up with "all" 
photos selected, but maybe DT could default to some small(ish) 
collection instead?


Also, maybe DT could only try whatever sorting option is active when 
having less than some number of photos, or be explicitly asked to. E.g. 
auto sorting only when having less than 1000 photos.


Also, thumbnail generation could be "lazy", only do it at some maximum 
rate, unless asked to do more


Maybe some of these already exist (as a preference, maybe)

Maybe.

In lighttable select the two images.

Hi
This is certainly a valid remark, the developers have their priorities,
and that's absolutely fine. It's open source, if you want something,
implement it -- my words (sometimes ;-).

On the other hand, creating a fork, in a proper manner, with the option
to somehow merge later, and then implementing something rather small, is
a lot of effort, for a small effect.

For example, I'm pretty sure that, in theory, my programming skills are
good enough to implement such a thing. But I would need to understand
the "architecture" of the source code, know how to implement effectively
and efficiently, following all the best practices the developers are
following because of their experience, etc. etc.



Precisely.

That is why "fork and do it your self" is a plain rude reply.



So it's valid to kindly ask the developers if they might spend a day or
three, when others might need weeks for the fork.

But if they say "No", that's a valid answer and has to be accepted.



Agreed, and agreed. Some one asked for it. I supported (and stuill 
support) the request, but obviously understand if it not a priority.


DT is quite good, I, and I bet we, thank the developers effort with it.

I do not that thank rude replies, including for those know-it-all that 
even know what I know, what I read, what I did.



One last note on the GUI reflecting the order of the modules.

Do the devs code "in order"? Do they code in assembly? Why not? Why 
don't they try to really understand how the code really work, and write 
it in the exact order it is executed by the computer? It is not the same 
if you JMP before you ADD, or ADD before you JMP...



Thanks. Let's try to believe others are trying to help. Be it users

No. Gimp's toolbox is not comparable because each tool there is

GIMPS' toolbox and DT's interface are comparable, because they are the 
way users find the tools.


Possibly one 'problem' is that DT's interface is used also to display 
modules' processing order.



Comparing it to Gimp's layers is not silly, they work the same way: 
there is an intrinsic order in which things are applied, and that order 
is represented by the order of the GUI.


But layers is one tool, of which the user chooses the order of, while 
DT's GUI is the whole app. Note that I am OK with a fixed pixelpipe 
pipepline, the devs studied it and found it produces better results this 
way?... great, as far as I am concerned


---

That said, what do I see as the problem and a possible improvement?


GIMP's interface has the tools, which users can order more or less at 
will, in the toolbox (you can also add menus, I do not recall if you can 
change the standard menus).


Tools are applied by whatever order the user wants.

There is one "undo" tool which displays that order and allows to get back.

(I am not saying it is good or bad, it is merely descriptive of the 
overall picture.)



DT's tools are (almost) fixed in the interface, and applied in the order 
shown in the interface.


There is a history tab on the left displaying the users' activation order.

(still merely descriptive, I hope)


OK, what is the problem, as I see it?

DT's interface has one more thing to display, compared to GIMP: the 
module application order.


DT's option to solve that is to have the tools in that fixed order on 
the interface. Well... almost...


The fixed order may make it hard to find the tools because whatever is 
the logical technical order to apply them may not be the order users 
think of them. That is why the devs had to select the order «with great 
care». But as someone pointed already in a fun way, you have to put your 
a sock before a shoe, but you may choose which shoe before which sock :) 
I also note that image editing is a technical but also an artistic task, 
giving 'the artist' as much freedom to follow their flow intuition as 
possible is a good thing.


Probably acknowledging that, and to make tools easier to find, there are 
tool groups ("tone group", "color group", etc). Note that when using 
those groups we already loose track of module application order. We get 
the order within that group, but we don't know about tools in other 
groups. I think the only way to see the full modules' order is by 
choosing the "show only active modules" tab.



So a implementation suggestions:

- Allow to sort the tools within the tool groups, or at least the 
favorites group.


THEN

- Keep the "show only active modules" tab in module application order

AND / OR

- Add a tab on the left, similar to the history tab, showing module 
application order.

DT is a really fine app.

It would be even better, in my opinion, if it allowed users to use it in 
a way that feels comfortable to each user. Allowing to sort the modules 
*on the GUI* feels like a reasonable request. I would like to.


Comparing to masks' order in GIMP is silly, that was not the point, I 
presume.

Compare it to GIMP allowing to order the tools in the toolbox, as it does.


Want to do it? Great!

Do not want to do it? Fine, too.

Devs may, and *should*, do whatever they think best. But pushing away 
suggestions with arrogant remarks will, in the long run, result in a 
poorer DT. For everybody.


Users might have good and original ideas too, you know? If devs kill the 
will to help, they'll lose. We all lose.

"Don't want to" is bit tough on people.

So something that does not solve my problem my way is, obviously, wrong.

Spending time, a year you say?, learning *the wrong thing* is a most 
obviously wrong option. So people don't.


So, instead of saying people are lazy or stupid, we should tell them 
that DT solves different problems. I don't know, I never used LR, but 
from what I read, the main advantages are price and better artistic control.


The price advantage is obvious, and most people coming from LR is 
probably coming for that reason, so no need to highlight it much, and 
anyway the site's main page already does so.


The site - main page and features page - also highlight a lot of 
goodies. Fine.


Probably it should also state upfront that we will be able to make basic 
editing right after installation but then to really get it going on it 
will take time, but then we will be able to do (this) and (that) better 
than (-LR-) just about anywhere else.


Yes, any good application takes time to master, anyone should know that, 
but it does not hurt if people gets reminded upfront, does it?

Re: [darktable-user] A Slideshow maker

I may be wrong, I am only looking into the file created by Impress 
but... no it doesn't...?


Impress does not create a video - in the sense that it is a sequence of 
frames displayd at fixed time intervals, e.g. 25 frames / second - it 
stores text, images, sounds, which gets arranged in a certain way (a 
slide), and is played on timings set per slide (and even within each 
slide) or on user command.


As far as I can see, Impress does not compress or resample, it stores 
the original data, using lossless compression. (It is a 'zipped' XML 
file - PowerPoint is likely in the same format but I do not have it at home)


Anyway, this is not about DT, as it seems.

[darktable-user] Error in an angle, in The Book

[Ricardo Kozmate.Net]

Hi list.

New user here, just read the Fornari, Latronico, and Manea's "Digital 
photo development with darktable". (see: 
https://www.darktable.org/resources/) I guess it is a good read for both 
novices and not-so-novice but new to darktable, like me. Thank you! And 
let me try to thank further with a small correction.


There is a mathematical error on the text at page 72. It reads: «Being 
the line [...] with slope of 45°[...] in the right portion of the figure 
[...] the slope is reduced to 22.5°»


The first line has a height of 1 for a base of 1, it's angle is 45º. But 
the second line has half the height, i.e. 0.5, which results in a angle 
that is not half of the initial one. Instead the angle is approximately 
26.6º - computed from  atan(0.5/1), or atan2(0.5,1), or similar 
depending on your calculator.


(To be pedantic, it probably shouldn't be "slope", as that is the ratio 
from height to base - but for a non mathematical text that is a very 
very minor issue :-) (See: https://en.wikipedia.org/wiki/Slope)


BTW, the heading at page 74 misses a 's' at "the *s*plit tone plugin"

again,
thank you
I hope darktable is maintained for a long time (I am changing from 
another that stopped being updated) as it looks promising just what I 
needed.
