I'm trying to use the new feature of lightroom 4.1 that allows us to edit 32bits floating point tif directly within Lightroom. The workflow seems easy enough when you have Photoshop but I do not.
I tried creating a 32bits floating point image using Luminance HDR but to no success Lightroom 4.1 does not recognize the file: "Preview not available for this file".
Is there any OpenSource software that can generate a 32bits tif file that would be compatible with Lightroom 4.1?
(Btw, I went into Luminance preferences and changed output type to 32bits floating point, it's also possible that Luminance works but I need to set some other option, if it's the case, I would appreciate if you can point me to the important settings).
