How to import .dng files

I have to work with .dng files and it looks like you can do it in Blender, somehow.

As stated in this question, it seems that you can import them but I don't know how; how do I do this?

• I tried to do as is stated here - blenderartists.org/forum/…, so I downloaded that test.dng from question you linked, opened it with Photoshop, and was able then to save it as TIFF or JPEG (or PSD, then having even more formats to select from). Jun 13 '15 at 13:11
• Ok, but I need to work in float point and preferably without using any proprietary software. Anyway, this question is about importing in Blender and it seems that it worked in that link. Jun 13 '15 at 13:24
• You could convert the files to exrs using natron or after effects
