Internals
- CameraVersion is written in the AutoIt scripting language. More informations about this very powerful, free tool can be found on the AutoIt v3 Homepage.
- The download archive is a self-expanding file. When it is started it creates a sub-folder on the selected folder, then it copies its source code and the helper tools into this folder.
- The firmware version number is stored in the JPEG's EXIF Data (MakerNotes) by the original Canon firmware
Firmware Revision : 1.01 rev 2.00
- this means 1.01B (second number is 1.00=A, 2.00=B, 3.00=C etc.)
- To read the MakerNotes, ExifTool is used:
