Hello Mike,

I'm thinking that since you have the window masked, you could use any 
number of tools:  Tone Curve, Tonemapping, Exposure, Low Pass...to name 
a few.

want to know the way to do it as I've described.

Re: [darktable-user] Re: Color checker.

2016-07-31 Thread A. Huntley


Hello Michael,

The Input Profile module is used to activate custom ICC camera profiles. 
The main issue you have is building an ICC profile from your color 
target. The ColorChecker Passport, for example, made by X-rite uses 
their own custom software to read the target image and build a DNG 
profile which can be used in ACR or Lightroom. I don't believe this 
profile could be used in DT.


Therefore, AFAIK you have two options: 1) find something that will 
enable you to build a custom ICC profile, or 2) have one built for you 
(perhaps the more wise option as you really have to know what you're 
doing with both the hardware and software that build these profiles.) 
Well, I guess there is a third option in that you could locate the 
profiles (if any) that came with your camera and use those in DT.


Good luck!

Regards,
Alan

[darktable-user] CHANGE UNIQUE FILE NAME FORMAT

2016-07-31 Thread Michael

when you are saving there is an option to 'create unique file name'. to
make it unique it appends an underscore followed by a number which
increments with each save. I don't like the underscore; I want it to be a
period. Can I change it?

Re: [darktable-user] A better starting-point for Nikon RAW-files

2016-07-31 Thread Edgardo Hoszowski

Same here with a D5100, with a D7100 all went fine, I have 2 or 3 different
profiles that give different colors cast, but so far there's always one
closer to the camera jpg.
Using the D7100 profiles on a D5100 raw seems ok too,  much closer to the
camera jpg.

Re: [darktable-user] A better starting-point for Nikon RAW-files

2016-07-31 Thread Jean-Luc CECCOLI

Hello,

 

So, I could try this, and was very impressed by the results.

It seems that decreasing the Linear value down to "0" gives results nearer to 
the actual subject,
whereas letting it to its default value gives more saturated colors, maybe as 
an attempt to match
the tastes of most people.
I could describe this as accuracy versus feeling.
Some other thing I could notice : after examining the generated icc files, I 
was expecting the results
to depend upon the sensitivity, however this seems not to be the case, as you 
stated in your previous
reply. And this seems very strange to me, as each profile seems to be built 
taking account of :

- 1st group of characters : maker (Nkx)

- 2nd group : camera model (2 to 5~6 digits)

- 3rd group : camera S/N

- 4th & 5th group : resp. always 01 and 1 so far

- 6th group : 2 digits 03 or 10

- 7th group : 1 digit, values so far are 0, 1, 2, 3 or 9

- 8th to 12th group values : resp. always 00, 10, 00, 00, 00 and 00 so far
- 13th group : always 05 or 06
- 14th group : always 00
- 15th group : 4 digits, sensitivity
- 16th to 19th groups : always resp. 0, 0, 32 and 476 for me.

I really don't know what to think about this all...

Rgrds,

J.-Luc

Re: [darktable-user] A better starting-point for Nikon RAW-files

2016-07-31 Thread Colin Adams

So I tried this (I have a Nikon D810).

When selecting any of the generated icc profiles except the last one, I get
a message:
"unsupported input profile has been replaced by linear Rec709 RGB!"
So I selected the last one, and set unbreak input profile to 0.0 as you
instruct.
The resulting image indeed looks to have slightly better quality, but it
has a green cast.
This is with darktable 2.0.5-1 rather than 2.0.4. I'm doubtful if that
should be making the difference though.
