Corrected some maker note info
The first field, which is identified by tag <code>0x1100</code>, is 80 bytes long. The meanings of its contents are not known, but the first byte Seems to always have a value of 1. The remaining bytes always seem to have values of zero, unless the photo used a sepia filter, in which case bytes <code>0x8</code>-<code>0x1a</code> (inclusive) are set. This field can be excluded from the maker note without invalidating the 3DS Camera maker note.

The second field uses tag <code>0x1101</code>. It is 64 bytes long, although its length can be reduced to as few as 20 bytes without issue. The first four bytes must spell "3DS1" in ASCII (with no null terminator).

The photo timestamp is represented by the number of seconds that had passed since the beginning of the year 2000 in the photographer's time zone.
The photo timestamp is represented by the number of seconds that had passed since the beginning of the year 2000 in the photographer's 3DS's time zone.
The system format timestamp is a UTC timestamp, in milliseconds, of when the photographer's 3DS system had last been formatted. Despite this value's potential usefulness for preventing previously-formatted photos from being viewed, it does not seem to be used.
