FAQ
HDR to PPM Conversion
What are HDR files?
The HDR file format (.hdr) is a raster image format designed to store high dynamic range (HDR) data, capturing a wider range of brightness levels than standard formats like JPEG or PNG. Developed by Radiance, it uses a 32-bit floating-point representation per channel, enabling realistic lighting, shadows, and highlights.
What are PPM files?
PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
