32-bit images

32-bit images can store approx. 4.3 Billion color / greyscale values

For reference, the human eye is perceived to register about 10 million colors.

This work utilizes either 32-bit HDR or 32-bit OpenEXR file format images.

32-bit images are used for applications such as:

  • Photography – to provide extra color / luminance range in the image*
  • CGI Rendering (Computer Rendering) via a process called Image Based Lighting (IBL)

* In reality, to actually appreciate this information as a print or via screen, the image is often ‘tone-mapped’
