Lightroom Dual ISO Plugin

This plugin allows you to convert Dual ISO picture from Lightroom directly to cr2hdr tools.

Lightroom v4 and more is needed.





How to use:

  • Right click on one or multiple selected pictures
    
    • Select : Dual ISO Converter (cr2hdr) (this option uses default settings, see below)
• Custom settings
  
  • Launch the Export Window
  • Right click on one or multiple selected pictures
    
    • Export selected photo(s)
  • Shortcuts
  • Windows: Ctrl + Shift + E / Mac: Command + Shift + E
  • Change what you want

Default settings:

> Plugin settings:

• Add suffix -dualiso to the output file
  
• Synchronize keywords with original picture
• Reject original picture (flag unmarked)
• Add converted file to all collections of the original
• No subfolder
• Show summary message
• Keep log file
• No keywords added by user (Dual-ISO is added by cr2hdr)
  
• No label defined

> cr2hdr settings:

• --amaze
• --cs2x2
• --no-bad-pix
• --fullres
• --alias-map
• --stripe-fix

This plugin is translate in english, french, german, portuguese and swedish. (feel free to send me a translated file).


/!\ DEV /!\ Download the lastest version of Lightroom Dual ISO Converter (cr2hdr) plugin (dev version).


How the plugin works:

• Pictures selected to export are listed
  
• Only CR2 and DNG files are supported (if file is not present, skip)
  
• Each picture, one by one is converted with cr2hdr (with defaults or custom args)
  
  • if cr2hdr 20bit and --same-levels are selected, all pictures are converted in the same time
• Picture is moved to subfolder
• Picture is renamed with suffix
• Picture is imported into Lightroom catalog
• Label is added
• Keywords are added (and created if needed)
  
• Synchronize keywords with original file
• Keyword Dual ISO raw or no Dual ISO is added to original file
  
• Parse log file to fill metadata with cr2hdr results
• Add picture to all collections
• Keep or remove log file
• Set the flag of the original file

How to install this plugin:

To install this plugin, extract zip and save folder cr2hdr.lrplugin where you want.
(Don't use hyphen mark "-" in path. This is an Adobe bug.)

On Lightroom, open the Plug-In Manager (shortcut Win: Ctrl + Alt + Shift + , (comma), Mac: Command + Option + Shift + , (comma)) and install it.

You can follow instructions from Adobe.

I've the pleasure to share with you my first Lightroom plugin!

Thanks, that certainly improves usability for newbies and people who keep the cr2 and dng in the same place. Still, with acr the dual_iso auto wb is broken so this workflow isn't without problems atm.

[Danne]

Great! Will test later

[a1ex]

Still, with acr the dual_iso auto wb is broken

IIRC you were the one researching this problem, along with engardeknave: http://www.magiclantern.fm/forum/index.php?topic=10265

Did you check if converting CR2's to Adobe DNG before running cr2hdr helps? Did you try to copy the exif info from an Adobe DNG file to cr2hdr output? I remember asking you this stuff, but I don't remember your answer (and my LR demo expired).

[Danne]

Wonderful little plugin. Don,t understand wb problem? Converted/exported my cr2 directly and it gave me superb result after processing my dng in lightroom. Perfect being able to work with dualiso straight within lightroom. Very convenient. Big thanks!

[g3gg0]

a big lol from my side when reading that post. why?

tonight i sat in front of the adobe SDK because i wanted to make dual iso files usable straight out of LR.
the intermediate step was just too inconvinient if you gave a graphical workflow.
then i decided, this is not a simple task if you never made a LR plugin. so i stopped since i didnt want to spend a week.
(i thought the right way is to generate a proxy file and using custom extensions)
i hoped that someone would come up with a proper solution.

and three hours after i stopped reading the SDK and example plugins you posted exactly what i was looking for.
wow, this was a perfect timing

thanks for this cool plugin, im gonna try it!

[Danne]

It is awesome.
My workflow
1 - importing the folder with dual iso cr2 files and I rate all of the 1 star(for being able to differ the originals from my resulting dngs)
2 - export to dng with the plugin
3 - back into the folder I choose to show "unrated" pictures and I end up with only my dng,s. Awesome indeed!
So nice.

*Of course one could simply point the dng,s to a specific folder to have the exported separately from the originals. Even better than above workflow

[g3gg0]

first feedback:

 - Lightroom 4.4
 - Windows 7 x64, German
 - installed cleanly
 - "C:\Program Files\Adobe\Adobe Photoshop Lightroom 4.4\cr2hdr.lrplugin"
 - .lrcat path contains spaces too
 - images are in path without spaces
 ! exporting fails with error message that that was no dual iso file
 -> problem was the binaries not being found - placed in a %PATH% directory and it works
 -> edit: i restarted LR and removed cr2hdr from the %PATH% directory and it suddenly works ... (?!?!)
 ! logfile per image "dualiso_xxxx.txt" is created, but empty
 -> didnt check yet where it comes from

conclusion:
aside from the mentioned install trouble a damn cool plugin which will push dual_iso a lot.

here the german translation:

[Danne]

I put the plug in straight to the lightroom plugin folder.
Rightclick program "lightroom" go to show package contents to contents to plugIns folder and put the plugin in there. Works straight away on mac.

Verbesserungsvorschlag:
"$$$/ML/Publish/noDualIso=Das Bild ^1 scheint kein dual ISO Bild zu sein"
->
"$$$/ML/Publish/noDualIso=Das Bild ^1 scheint kein Dual-ISO-Bild zu sein"

Ciao
Walter

[g3gg0]

yep, good idea

[chris_overseas]

- Lightroom 5.3
- Windows 7 x64, English
- Installed fine from a separate directory (F:\Lightroom\Plugins\cr2hdr.lrplugin)
- Images are in a path that contains spaces
- Selected several images, right-clicked and exported, everything worked fine!

Note that I copied over new versions of cr2hdr.exe (I used the 20 bit version), exiftool.exe (9.54) and dcraw.exe (9.20) since the included ones appear to be quite old?

Bugs/issues:
- I get an empty log file for each image (as pointed out by g3gg0)
- The cr2hdr command line window opens in the foreground (is it possible to open it minimised, hidden or behind Lightroom?)
- The DNGs were created fine and the corresponding CR2 says it is in a stack, but the DNGs don't appear in the filmstrip or library (grid) view. [OK, turns out that's because I had just imported the CR2s then exported directly, so my library selection was "Previous import" rather than the folder I'd imported. I don't think that can be considered a bug?]

Overall, this looks great and will definitely simplify my workflow. Thank you!

[garry23]

A simple report that this plugin works perfectly: well at least in my set up, ie LR5.3 and 64bit Win7.

I just right click on the image and select cr2hdr and magically the DNG returns to Lightroom, I don't even need to synchronize the folder in library view as I need to do with some plugins.

It means that we now have 1-click processing of dual-ISO.

Many thanks to the author of the plugin.

[Danne]

All my logfiles (.txt files) contain all infomation about the conversion process. No one is empty.
I,m on a mac and lightroom 4.4

[kichetof]

Thank you all for your feedback! I appreciate

I'm glad that this plugin makes your workflow easier!!

So, my workflow is Mac and it's really more simple to write shell command on it!

I spent a lot of hours to find a way to launch the command on windows and I'll find a way to optimise it! (see my post on dev ml forum and Lightroom discussion)
To windows users:

Could you add before LrTasks.execute (where cr2hdr.exe is call): mlLog:debug(command)
And paste result from windbg or anything else debugger

Could you add /B and/or /MIN after /WAIT on windows command var and tell me if it's more user friendly

Normally all path are escaped so I don't understand why you don't have output file!

I'll update dcraw and exiftool (forget to commit new version)

Thank you for deutsch translation! I'll add it tomorrow

If you're a pro with lua and Lightroom sdk feel free to help me to make code more robust

[kichetof]

I'm happy to help you! For one time it's me who can help you!

[chris_overseas]

(For those wanting to play with the plugin code, make sure you go into LR's Plugin Manager and enable "reload plugin on each export" so your changes to the script are picked up and recompiled each time it runs)

• /MIN works nicely - the window still opens but is minimised so doesn't cause any real problems.
• /B works without any window appearing at all but ONLY if /B appears before /WAIT. If /WAIT is first the /WAIT seems to be ignored and I get "Doesn't look like interlaced ISO" (http://superuser.com/questions/355341/windows-start-wait-b-not-working).
• The log file is empty because the shell running "start" is having its output redirected to the logfile rather than the window that is opened by "start" (which is where the real output is). Passing "dualiso.cr2 > dualiso.log" through as a single parameter doesn't work. What does work is escaping the redirect with ^> instead.

Personally I prefer /B over /MIN. I also added /BELOWNORMAL to reduce the cr2hdr priority slightly and help keep the computer responsive.

Here is the updated code incorporating the above changes:

Code: [Select]

command = string.format('"start /D "%s\\bin" /B /WAIT /BELOWNORMAL cr2hdr.exe "%s" ^> "%s""', pluginPath, filePath, output)

I wonder if there is a way to run multiple cr2hdr conversions in parallel? Also since I'm not really interested in having the log files left behind, I've removed that feature from my copy. Maybe there's a way to make it optional. I know additional settings can be added to the Plugin Manager dialog though I haven't looked into how to do that yet.

[mad.eos]

A huge thanks from my part kichetof! You're the man!

This has, in my opinion, turned a whole new leaf in the post processing workflow for whoever works with lightroom!

Very good work!

By the way, have you already updated your zipfile with the new cr2hdr files?

[Luiz Roberto dos Santos]

This will be very helpful, big thanks.
So, this is on Half-res blending mode? Any chance to apply blending full-res? 0k, that requires Octave, but it could be done. Moreover, as mentioned above, perhaps the new features of 20bit version and "film-curve" could help.
I will test soon and bring you the feedback. Also, try to do the translation into Portuguese - BR.

[painya]

This is not to the ML Gurus.
To the beginners!
Here is a quick user friendly guide-
Open LR
File>Plugin manager
Click on the folder
Restart LR
Right click on your image
Export>ML>Cr2_hdr (or whatever it is)
Enjoy!

[Danne]

I wonder if there is a way to run multiple cr2hdr conversions in parallel?

I just ran exports in several export operations. Tried running 5 exports simultaneously of cr2 to dng and they work in parallell that way. Occassionally I get a pop up window telling me an internal error has occured but it exports anyway so I just ignored and synchronized the folder when finished.

The error code


*It appears the error code does indeed affect some pictures only getting halfway through the process so Running several export operations simultaneously isn,t stable.

[kichetof]

Note that I copied over new versions of cr2hdr.exe (I used the 20 bit version), exiftool.exe (9.54) and dcraw.exe (9.20) since the included ones appear to be quite old?

Updated !

Yeaaaah !! Big thanks for that !!! (I'm more comfortable with a shell terminal)

I don't know how to make it, but I'll read the lightroom SDK to find it

Thanks for this try ! I'll investigate how to make it possible!

New version 1.0.1, I'll update first post soon !

[Marsu42]

IIRC you were the one researching this problem, along with engardeknave: http://www.magiclantern.fm/forum/index.php?topic=10265

Well, he was researching it a bit and quickly came to the conclusion I arrived at even w/o some days of trial & error - it's too complex for us to figure out the algorithm how acr arrives at its wb values from the tags embedded in the cr2 :-(

thanks for this cool plugin, im gonna try it!

Maybe you can figure out to get the correct "as shot" wb from acr? This is a real pita, if you didn't shoot a wb/color card or a non-dual_iso shot to compare it's complete guesswork what the correct wb/tint is.

[fotogemeinschaft_de]

After the first export (which was ok) I always get the following error with every other Picture:

'Already treated' - 'The File xy has already converted to dual iso'
(LR 5.2)

In fact the file was NOT converted.

I have found the reason for this behaviour by myself: The plugin doesn't add numbers to the converted files; my filenames are rather long and the plugin therefore produces always the same filenames in the same directory.

After every single conversion I have to rename the converted file manually. A batch-job will therefore not be possible but nevertheless the integration in LR is great..

Ralf

[vertigopix]

Thanks for this plugin !   
Checked you version 1.0.1 and working perfectly for me (LR 5.3 64bit, Win7 64)

Great job !
