Part 6/8:
A practical example of this is seen in cameras like the Canon T90, which can recognize various films based on their coded information. The simple arrangement of information via these patches greatly simplified the photography process while contributing to the precision of exposure settings.
Accessibility and Limitations of DX Encoding
Despite its brilliance, DX encoding wasn't available on all cameras. While higher-end models could utilize the full range of coded information, many consumer cameras had limitations. For example, some models could only check certain bits of data, resulting in simpler exposure adjustments but ultimately preserving usability.
