| Description | Kodak – the photography giant needed an effective way to archive images on various data storage devices, so they developed the Photo CD format. Capturing images with cameras featuring advanced lenses and scanning documents with high-definition scan heads often results in high-resolution copies that can consume a large amount of memory space on Kodak devices. Therefore, the PCD format employs an image compression system to encode images in 24-bit slices. A PCD file can accommodate images of varying resolutions, with the highest resolution being 6144×4096 pixels. |
| Technical details | Although the PCD format technically supports image resolutions as high as 6144×4096 pixels, images are typically saved onto storage media at a resolution of 3072×2048 pixels. It is worth noting that both of these resolutions maintain a color depth of 24-bit. Saving images in the PCD format is reminiscent of the high-resolution video compression technology patented by Apple Inc. |
