Re: [darktable-user] magic-lantern dual-iso feature

I was successful by downloading the
magic-lantern src package and building it from there with
  the appropriate defines. Not sure if this is true, but assumed it
  would be camera dependent. Used make and the resultant cr2hdr
  works like a charm.

Hi,

I want to give magic-lantern a try and test the dual-iso feature. But unfortunatly I can not get cr2hdr compiled. And I dont know how to handle the dual-iso files in DT without cr2hdr.

Does somebody know of a download link for a cr2hdr binary?

Yep. Somewhere I found a thread that said to link libOpenCL in
darktable/plugins which I did. Removed that and last error went away
but the same main issue of not finding "image support" remains.

I'm using a AMD Radeon R5 230, which supports OpenCL 1.2 on Fedora 25 (I
jumped to F25 yesterday due to blowing my F24 system yesterday trying to
install fglrx)

So it appears that Darktable requires OpenCL 1.2


darktable (small letter d) works well with any OpenCL 1.x and OpenCL 2.x 
version. As written above we have some minimum requirement of the 
devices, though.




This leaves me with a number of questions:

1) why is the activate OpenCL support ticked as enabled, when opencl is
clearly not functioning?


This is a known UI glitch.

Ulrich



2) I thought mesa had OpenCL 1.2 support, but apparently not?

3) how does one get OpenCL 1.2 on fedora using Radeon cards as there is
no specific fedora driver on AMD site?

or

4) what I'm I missing?

I did try and find some specific answers but wasn't successful, so
thanks for your patience and support.

Regards.

There's a few different scripts floating around to help you extract the white balance info from your 
images.  Here's what I do:


Download latest exiftool from http://www.sno.phy.queensu.ca/~phil/exiftool/ the first link will do. 
I find the version in Ubuntu is too old.


sudo apt-get install git ruby ruby-nokogiri
mkdir wd && cd wd
tar xvzf ~/Downloads/Image-ExifTool-10.36.tar.gz  # this is the exiftool 
download
export PATH=$PATH:~/wd/Image-ExifTool-10.36
git clone https://github.com/darktable-org/darktable.git
cd 
rm -rf ~/white_balance.txt
for file in *; do ~/wd/darktable/tools/extract_wb "$file" >> ~/white_balance.txt ; echo >> 
~/white_balance.txt ; done


Now, have a look in the ~/white_balance.txt file.  You will see the extracted white balance 
information for each image that you made.  For me, I got more than one line per image, so I had to 
go through and select the one that was the setting that I set the camera to.  Delete the other lines 
so you end up with one line per image.


Add a comment to the top of your file with camera name and version like this:

  /* Fujifilm X-T10 Firmware Version 1.21 */

Now, you can either just post this info into a redmine issue:

https://redmine.darktable.org/projects/darktable

Or you can test them out first by copy/pasting them into the source code of darktable and building 
and installing to test.  If you're running darktable 2.0.x, the instructions are here:


https://redmine.darktable.org/projects/darktable/wiki/Building_darktable_20

Version 2.2 rc is here:

https://redmine.darktable.org/projects/darktable/wiki/Building_darktable_22

After you check out the tag for the version you want to build, you need to copy your new white 
balance values into this file:


~/wd/darktable/src/external/wb_presets.c

Then you build and install, and run your newly installed darktable by doing:

/opt/darktable/bin/darktable

Make sure you back up your database before running your modified darktable 
version though!

cd ~/.config
cp -a ./darktable ./darktable.bak


Hope that helps!  Also, you might want to consider shooting additional images with the white balance 
fine-tune settings on your camera (this is typically 19 images per white balance preset, though). 
This enables the fine tune slider in the white balance module of darktable which I find really useful.

Rob

[darktable-user] OpenCL support on Fedora 25 using AMD R5

[Mark Heieis]

  
  
Hi 
  
Up until yesterday, I was happily
working with Darktable 2.*, thinking I had opencl functioning,
although it didn't seem very speedy. After all, the graphics has
it, mesa has it and looking at the core options, it was checked.
But after reading some of the threads from the past 2 days
regarding opencl, I took a further look.
I tried toggling "activate OpenCL support"
to "off", but if was fixed in check mode. However, further
looking a hover message saying, "Not available on this system",
appeared. Now I'm confused and understand why it wasn't speedy.
  
Some output from clinfo:

I have the same problem, but for me, it's only vertical versus
horizontal, so I created 2 styles:

watermark: line/frame horizontal
watermark: line/frame vertical

and I apply the appropriate style at the export. So I end up with 2
sets of exports, the horizontals and the verticals.

see: http://www.sritch.com for how it looks when I did it.

[darktable-user] Watermark with origin point from left/right corner?

[Marek Vančo]

Hello,

   I would apply watermark on my images (signature), If I create style, 
I have a problem.
Every image have a differents ratio/size and style is not aplying on the 
same place.


Is there a possibility to parameter watermark with origin point based on 
selected corner of image?
exemple: I want my signature (watermark) on every image 5px up from 
bottom side and 5px left from right side.


So signature will by always on the same place (despite of format/size of 
image).

How to do it?

Excuse me my english please!
Thanks you very much!

[darktable-user] Cannot print fine art paper with turboprint from darktable

[Normand Fortier]

I am getting acquainted with turboprint and would like to print from 
dartktable on an Epson p800 printer.


I can print using the "auto-sheet feeder" (loading from the top of the 
printer), but not on thicker paper ("fine art") loaded through the front 
of the printer.
I can however print using front loading from Gimp, with the same 
settings, so I assume the problem is not with turboprint.


When I try from darktable, the printer displays an error message:

"Replace with the following paper.
- Auto Sheet feeder
- Letter
- Prem. semigloss."

I would like to know if anyone has been able to print from darktable 
through turboprint using the front-loading in the epson p800 or a 
comparable printer and if any special settings had to be set.


Thank you!
