About PPM
Portable Pixmap
The color member of the Netpbm family: uncompressed RGB pixels after a short text header, in binary or plain-text form. Use it as a simple interchange format for scripts and image tools that read raw pixels.
About HDR
Radiance HDR
The HDR format from the Radiance renderer, storing each pixel as red, green and blue values with a shared exponent byte, so it holds a far wider brightness range than 8-bit images. Most HDRI environment maps ship in this format. Use it to light 3D scenes, or convert from it to get an ordinary 8-bit preview.
