Local Lab build

(Desmis) #101

Yes you can :slight_smile:

(Desmis) #102

I will push a change tomorrow :slight_smile:

(Desmis) #103

I just push a change with

  1. inverse lightness as ask by Dngimage
  2. many bugs solved
  3. I have add (with many difficulties!!) a curve L=f(L) for each control point - for “color and light”. To activate this curve, you must have “lightness” or “chrominance” different of zero (0).

Excuse my bad english !

Thanks @jdc :slight_smile:

I still don’t get 100% black but it darkens more than before. I find this very useful to darken areas in an image. Also, one note, *.mip from previous versions need to be deleted or it will crash, but I think we know that. One suggestion: it would be nice to collapse some of the taps in the Local Lab menu area. It is getting crowded there.

I just push a change.

I have update GUI with expanders. Now you can hide or show commands.
You can also - enabled or disabled each family (color , retinex, sharp, etc.). But this choice is for all Control points.

I have slightly change the code for dark in inverse mode. For sliders = -100 ==> L = 0. But we are in Lab* mode and you saw chroma, If you want a dark - black image, you must change chrominance, near zero.

Great work!

(Desmis) #108

I push a change.

It fixed the crash (in some cases) when using curve L=f(L).
To activate curve, you must have “lightness different from 0”

I hope this time, it’s the good :slight_smile:

I recommand to clean cache and delete *.mip files…It’s probably useless, but …

André, merci

If I try LocalLAB RT crashes immediately.
Without using LocalLAB it works.

Did you clean the cache and deleted all *.mip files from the older versions?
Try also creating a new PP3 with the new version.
Sometimes old PP3 and MIP files can cause problems.
I hope this helps.

or show commands.

I’ve noticed that when you exit RT and come back later, it “forgets” to keep some of the options in the expanders hidden. It always shows all the options under Local Lab.

I added a curve (arbitrarily) L = f (H) to test the possibility of curve where the abscissa is hue. You can, if you tell me which, add any curve to the module “color and light”

For expanders, the principle is identical to those used in Wavelet

  1. the enabled / disabled selection is stored
  2. do not keep in memory open / closed
    To change this (at least I believe it) it is necessary to make a change in the GUI of RT. It’s not in my skills!



You can also try to put your photos in a subdir with path containing only unaccented ASCII characters.

If it doesn’t work then the best is to use a debug build and generate a back trace and file a bug report.

This is the right solution.

Hi @jdc Desmis,
Where can I get this update?

(Desmis) #118

To avoid crashing when the file path contains non-ASCII characters, I changed the location of the * .mip files.
Now by default, they are in “profiles” next to the “cache” folder.
You can choose the location, either “profiles” or as before next to the input file to be processed in:
Preferences / Image processing / Mip profiles
If you choose “profiles”, no crash problems due to NON ASCII characters, but if you have the same image file in different folders, there will be only one file "mip"
If you choose “Next input files”, the system crash with path with NON ASCII, but you can have one mip file, for each same file in different folders.

Normally at start-up, the system should not crash, but it will ignore the previous settings.

I do not provide build, wait for someone to do it. :slight_smile:


@dngimage You can check here for new nightly W32 and W64 builds (release and debug) or go directly to https://drive.google.com/open?id=0B2q9OrgyDEfPS2FpdDAtMVI1RG8 for W64 builds.
As the dev are now very active, I frequently make new builds.

Thanks for the new improvements. Local Lab is looking good.

Thanks for the new builds. RawTherapee_WinVista_64_release_locallab_4.2.1340.zip is running fine here.
