darktable ep 040 - The watermark module

[@minuteman2006]

Excellent job sir with explaining how to use the Watermark module. Easy and simple to follow.

[@audio2u]

Cheers!

[@sheridanprice9821]

For Windows look under c:\program files\darktable\share\darktable\watermarks. Excellent video. I recall Harry Durgin had some videos where he used the watermark module to change out portions of a photo.

[@audio2u]

Cool!

[@MrAntec300]

Thanks!

[@PL-jw1my]

Thanks for your explanation of the watermarks module, very helpful.

[@audio2u]

No worries!

[@chhil]

For windows, copy the svg watermark files in the watermark folder of ypur darktable install. Easiest way to find the folder is to search for "watermark" in your darktable install directory. On my machine its located at C:\Program Files\darktable\share\darktable\watermarks

[@borispejic170]

Thank you Bruce.

[@jasonmacdonald6571]

hi all! just an update, a transparent PNG will now work as a watermark too

[@audio2u]

Thanks for the info!

[@AlgoFodder]

Sometimes I like to set "simple text" and put a single space in the text field. This gives a totally blank watermark, i.e. does nothing! But then I choose uniform blend, ~ 30-50% opacity, and either overlay or softlight method for a quick contrast boost. Why do this? The advantage is that watermark is (afaik) last in the processing chain, so this contrast boost will come after any other changes I make, which can be handy sometimes.

[@audio2u]

Interesting! Cheers.

[@loverdomi]

Great video, thanks a lot. I am happy to find your videos! Great explanation

[@audio2u]

Thanks!

[@peterrockell1527]

Thanks for the frameing idea, I'm going to nick it :-) I'd already figured out much of the watermark tool, but you've just added more depth to my shallow knowledge.

[@audio2u]

Glad I could help!

[@bojerauff]

Thanks Bruce

[@audio2u]

No problem!

[@rushabhjethwa6279]

Thanks Bruce. I got the answer I was looking for.

[@philsilverman7431]

Great stuff Bruce, thanks very much

[@audio2u]

No worries!

[@nonsolovita]

clear and good quality video as always, thx

[@audio2u]

No worries! 😃

[@joaovtaveira]

12:10 and after doing that and before be able of use it, press the circulating arrow on the top right of this module to refresh it.

[@audio2u]

Yeah, I realised that after I'd finished the video!

Just a very silly note on the pronuntiation of Hugin (so that you have mentioned this question a couple of times in another videos). I have not real info, but the icon of the program it's someone giving a big hug, so... I can Imagine ti will probably be somthing like hug-in (the idea of embracing toghether the pictures that form a panorama). Just my guess...

[@audio2u]

I always thought it was simply outstretched arms, like "the panorama was THIS wide".... Who knows? 😃

[@bubulubugoth]

which distribution do you use? For the svg, you can import a PNG/JPG into inkscape and then export it as SVG without any further tracing, and it will work too...

[@audio2u]

I'm on Linux Mint 19. Thanks for the tip!

[@SonGoku-mg9db]

Hi Bruce, a really good video! I have one question. How can I build a second row when I write my own simple text? It stays just in one row ...

[@audio2u]

Good question! I THOUGHT it was shift+return, but that doesn't appear to work.

[@Bigjuergo]

Windows10 folder in my case: C:\Program Files\darktable\share\darktable\watermarks Just convert *.png (I used transparent alpha channel in GIMP) online to *.svg and copy in your watermark folder :-) thx for this helpful video Bruce!

[@audio2u]

Cheers!

[@ToreBusch]

A cool thing about svg is that you can have variable strings that gets substituted within the svg document. So you can add watermarks that have date, title and description per image if you want. You can see a list of available variable strings in the documentation, www.darktable.org/usermanual/en/effect_group.html

[@audio2u]

Yeah, I should have included that in the video. Thanks for the reminder, Tore!

[@rosstucker3669]

Thanks Tore. This was going to be my main question here.

[@Bigjuergo]

is it possible to place an invisible watermark for copyright detection?

[@audio2u]

If it's invisible, how would it be detected?

[@Bigjuergo]

@@audio2u an identifier based on nearly imperceptible patterns

[@audio2u]

I don't know about that, but you can always use the watermark module, set a mask with uniform blending, and then reduce opacity to 5%.

[@JillesvanGurp]

~/.config on mac as well. Also, obligatory reference to Harry Durgin here. He shows in several of his videos how you can export your darktable image, wrap it in an svg and then bring it back as a watermark for some primitive compositing.

[@JillesvanGurp]

kzbin.info/www/bejne/r4Gto6Glesx6a9k this is a good example of that.

[@audio2u]

Nice one!

[@wido123123]

Hi Bruce. Do you think you can make a Tutorial on Channel Mixer? There are some videos from Boris Hajdukovic, and he uses this module a lot, but I still don't get what is he doing

[@audio2u]

It's on the list of subjects to cover!

[@joaovtaveira]

You could also make a video about the frame module.

[@audio2u]

Yeah, it's on the list!

[@theyear1500]

My issue is why does the watermark effect the histogram?

[@audio2u]

Because the histogram is reading ALL pixels as they will appear at the output/render stage... That would be my guess!

[@theyear1500]

@@audio2u that is what I figured as well, but the watermark is only applied at the last stage. No other module effects it. Yet it changes the histogram while you edit. I just wait to apply it right before exporting, but it seems like they could have made it be ignored.

[@audio2u]

What you could do is create a style that only adds the watermark. Then, create an export preset which includes that style. That way, you don't need to add the watermark during your processing.

[@theyear1500]

@@audio2u thank you, that is a great idea.

[@janderboven4711]

Hello, Isn't there a way to use the color picker in Darktable to define a color for your svg.file?

[@audio2u]

Sorry, I can't answer that right now. I'm on the Maldives on holiday. I'll try and look for an answer when I'm home next week.

[@janderboven4711]

Enjoy your holiday!

[@malaca123]

Is there a way to make a watermark (.svg) that let me change it to a custom colour?

[@audio2u]

If you're on linux, inkscape is your best bet for creating .svg files. Not sure about mac or pc.

[@malaca123]

Thanks! I Didn't express myself correctly, what I meant was, can I create a black watermark on inkscape and later change the colour in darktable?

[@audio2u]

No, I don't believe so.

[@pedrowdiniz1978]

Muito bom ! Parabéns !

[@joaovtaveira]

Your Winter starts on June the first?! That's strange to me. I thought it started on June the twenty first when our Summer starts.

[@audio2u]

I guess you COULD claim the solstice as the beginning of the season, but most people (at least in Australia) simply go by the beginning of the next month.... December 1st for summer, April 1st for autumn, June 1st for winter and October 1st for spring.

[@leona_devon]

I would like to see how you created that instagram frame

[@audio2u]

Sure thing. I'll do a quick patreon-only video for you, Leona!

[@kenhalal375]

Was so looking forward to that shoot in the mud. No reason to keep watching these videos through the winter. See you in the spring. JK

[@audio2u]

Haha.

[@RicoResolves]

Dear Bruce, 15 minutes about the watermark module..Really? Did you have too much time on your hands 🤣? Just kidding man, well done once again 👍

[@audio2u]

Thanks Rico!

[@audio2u]

Plus the extra 5 mins for the Patreon episode extension! 😃

[@RicoResolves]

@@audio2u no worries Bruce, I was just busting your balls. Everytime people talk about darktable I guide them to your page for real in depth tutorials and tell them that my channel is more focused on creative tutorials. You're doing a fantastic job helping people that have no knowledge or darktable understand how this program works without having them invent the wheel themselves.

[@audio2u]

Thanks mate! 😃

[@lylestavast7652]

first ? Good video Bruce.

[@audio2u]

First what?

[@lylestavast7652]

@@audio2u 1st comment ! :) Regarding the location for svg watermarks on Windows - mine is C:\Users\myusername\AppData\Local\darktable/watermarks - you can also put them in a product directory (which you may or may not have access to on Windows due to Administrator owning it...)

[@audio2u]

Thanks for the windoze-specific directory info, Lyle! That's great. Cheers. :)
