I found out recently, that Lightroom fails to reproduce in-camera white-balance that I have set for UV-photos.
This can be best illustrated by showing the in-camera JPG (1) and the RAW-file (2) after opening it in LR4. Other RAW converters like UFRAW/GIMP or Silkypix get the WB correct, but I would love to keep my workflow that is currently based on LR.
Camera: Panasonic Lumix G1, modified for UV and IR photography.

Any hint about a feasible remedy is highly appreciated.
Best wishes and thanks in advance,
Nico

about image No. 2: This is how LR4 renders the file with the WB setting “as shot” – that is more than slightly off …

Since ACR & LR are designed to assume a normal sensor response with an IR cutoff built in, shooting without an IR cutoff scrambles the normal white balance when using the DNG Profiles used by ACR/LR. The only remedy is to edit a DNG Profile using the free DNG Profile Editor (http://www.adobe.com/cfusion/entitlement/index.cfm?e=labs%5Fdngprofileeditor) from Adobe Labs. The user guide for DNG Profile Editor (http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/cs6/DNGProfile_EditorDocumentation.pdf) has a tutorial for editing a profile for use with IR modified cameras. It's a 3.93MB PDF.

Thanks, Jeff!
I'll try that and let you know how it works.
Best, Nico

I have played with DNG editor. However, I don’t think that this is the solution that I was looking for. Maybe it’s feasible to create a suitable profile, but it seems to be a quite tedious process. I will probably use another RAW converter that simply imports the camera settings without applying some annoying changes during development.
