.SH NAME
Image::ExifTool::Pentax \- Pentax/Asahi maker notes tags
.SH SYNOPSIS
.IX Header "SYNOPSIS"
This module is loaded automatically by Image::ExifTool when required.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module contains definitions required by Image::ExifTool to interpret
Pentax and Asahi maker notes in EXIF information.
.SH NOTES
.IX Header "NOTES"
I couldn\*(Aqt find a good source for Pentax maker notes information, but I\*(Aqve
managed to discover a fair bit of information by analyzing sample images
downloaded from the internet, and through tests with my own Optio S, Optio
WP, K10D, K\-01 and K\-5, and with help provided by other ExifTool users (see
"ACKNOWLEDGEMENTS").
.PP
The Pentax maker notes are stored in standard EXIF format, but the offsets
used for some of their cameras are wacky.  The Optio 330 gives the offset
relative to the offset of the tag in the directory, the Optio WP uses a base
offset in the middle of nowhere, and the Optio 550 uses different (and
totally illogical) bases for different menu entries.  Very weird.  (It
wouldn\*(Aqt surprise me if Pentax can\*(Aqt read their own maker notes!)  Luckily,
there are only a few entries in the maker notes which are large enough to
require offsets, so this doesn\*(Aqt affect much useful information.  ExifTool
attempts to make sense of this fiasco by making an assumption about where
the information should be stored to deduce the correct offsets.
