Portable Float Map (.pfm): The HDR format with 32 Bit is similar to RAW a simple image, therefore very compatible, but also memory consuming (12 MB for 1 MP).
PFM (Portable Float Map) is an unofficial extension to the pbm image format collection that supports HDR imaging, namely a floating point value per r,g,b [or a single floating point value for grey scale HDR images].
