About the MAC format
MAC — MacPaint Image
MAC is the native bitmap format of MacPaint, Apple's original paint application bundled with the first Macintosh in 1984. MacPaint files are monochrome (black and white) 576×720 pixel images that represent one of the earliest consumer bitmap graphics formats in computing history.
Common uses
- Recovering early Macintosh MacPaint artwork
- Historical computing and art preservation
- Converting classic Mac graphics to modern formats
- Computing history archive projects
About the HDR format
HDR — Radiance RGBE High Dynamic Range
HDR (Radiance .hdr) is a high dynamic range image format developed for the Radiance rendering system. It stores luminance information far beyond standard 8-bit images using a shared-exponent encoding, making it the standard for HDR environment maps in 3D rendering.
Common uses
- 3D rendering environment maps (IBL)
- HDR panorama photography storage
