<h2><a name="awk">A Note to Unix Power-Users</a></h2> <blockquote>If you feel
the need to use "find" or "awk" in conjunction with ExifTool, then you probably
haven't discovered the full power of ExifTool.  Read about the <code>-ext</code>,
<code>-if</code>, <code>-p</code> and <code>-tagsFromFile</code> options in the
<a href="exiftool_pod.html">application documentation</a>. (This is
<a href="mistakes.html#M3">common mistake number 3</a>.)</blockquote>

<h2><a name="system">System Requirements</a></h2>

<p>Requires Perl 5.004 or later.  No other libraries or software required, but
some optional Perl modules may be added to enable certain ExifTool features (for
details, see the DEPENDENCIES section of the README file included in the full
distribution).</p>

<p><b>Windows users:</b> A <a href="#alone">stand-alone Windows executable</a>
version of ExifTool is available which doesn't require Perl.  You can also use
the pure Perl version if you already have Perl installed. (You can get a good,
free Perl interpreter from
<a href="http://www.activestate.com/activeperl/">activeperl.com</a>.)</p>

<p><b>Everyone else (Mac, Unix, etc):</b> Don't worry, you already have
Perl installed.</p>

<h2><a name="running">Running ExifTool</a></h2>

<p>The <a href="exiftool_pod.html">exiftool application</a> provides a
convenient command-line interface for the
<a href="ExifTool.html">Image::ExifTool</a> Perl package (both included in the
full distribution). Once you have downloaded and extracted the distribution, you
can immediately run exiftool (without building or installing) by typing
"<code><i>DIR</i>/exiftool <i>FILE</i></code>" (or
"<code>perl <i>DIR</i>/exiftool <i>FILE</i></code>" in Windows), where
<code><i>DIR</i></code> is the exiftool directory and <code><i>FILE</i></code>
is the name of an image file, including directory name. Read the
<a href="install.html">installation instructions</a> or the README file included
in the full distribution for help installing ExifTool.</p>

<p>Many command-line options are available to allow you to access a wide range
of features.  Run exiftool with no arguments for a
<a href="exiftool_pod.html">complete list of available options with
examples</a>.</p>

<h3>Running in Windows</h3>

<p><b>i) From the command line:</b></p>

<p>The Perl application ("<code>exiftool</code>") is run by typing "<code>perl
exiftool</code>". Alternately, you may be able to rename it to
"<code>exiftool.pl</code>" and type "<code>exiftool.pl</code>", but this
requires that the proper Windows associations have been made for the
"<code>.pl</code>" extension.</p>

<p>The stand-alone version ("<code>exiftool(-k).exe</code>") should be
renamed to "<code>exiftool.exe</code>" to allow it to be run by typing
"<code>exiftool</code>" at the command line.</p>

<p>If the exiftool executable ("<code>exiftool.pl</code>" or
"<code>exiftool.exe</code>") is not in the current directory or your system
PATH, then its directory must be specified on the command line (eg. by typing
"<code>c:\path_to_exiftool\exiftool.pl</code>" or
"<code>c:\path_to_exiftool\exiftool</code>").</p>

<p>Note that when typing commands in the "cmd.exe" shell, you should use double
quotes instead of single quotes as shown in some examples.</p>

<p><b>ii) Stand-alone version in the Windows GUI:</b></p>

<p>Double-click on "<code>exiftool(-k).exe</code>" to read the application
documentation, or drag-and-drop files and folders to run exiftool on the
selected files.</p>

<p>Simple options may be added inside brackets in the name of the stand-alone
executable.  (But note that the characters <code>/\?*:|"&lt;&gt;</code> may not
be used because they are invalid in Windows file names.)  In this way, the
behaviour of the drag-and-drop application can be customized.  For example:</p>

<blockquote><table class=norm>
<tr><th>Executable Name</th><th>Operation</th></tr>
<tr><td><pre>exiftool(-k).exe</pre></td>
<td>Print meta information in window and pause before terminating.</td></tr>
<tr><td><pre>exiftool(-k -a -u -g1 -w txt).exe</pre></td>
<td>Generate output "<code>.txt</code>" files with detailed meta information.</td></tr>
<tr><td><pre>exiftool(-k -o %d%f.xmp).exe</pre></td>
<td>Generate sidecar "<code>.xmp</code>" files.</td></tr>
<tr><td><pre>exiftool(-copyright='Phil Harvey').exe</pre></td>
<td>Add copyright information (and don't pause before terminating).</td></tr>
</table></blockquote>

<p><b>Hint:</b> Options may also be added to the "Target" property of a Windows
shortcut for the executable.  Using a shortcut has 3 advantages over adding
options in the file name:  1) different shortcuts may be created without
requiring multiple copies of the executable, 2) characters which are invalid
in file names may be used, and 3) the shortcuts can be given more meaningful
(and convenient) file names.</p>

<p>As well, it may be useful to increase the window and buffer sizes to display
more information:  Right-click on the window's title bar then select
"Properties" from the menu and change the window layout settings.</p>

<h3>Verbose and HtmlDump Output</h3>

<p>The <a href="verbose.html">Verbose</a> (<code>-v</code>) and <a
href="htmldump.html">HtmlDump</a> (<code>-htmlDump</code>) options print additional
information that can be very useful for debugging or when decoding new tags.</p>

<h2><a name="tagnames">Tag Names Explained</a></h2>

<p>A tag name is a "handle" that is used to refer to a specific piece of meta
information.  Tag names are entered on the command line with a leading
'<code>-</code>', in the order you want them displayed.  Valid characters
in a tag name are A-Z (case is not significant), 0-9, hyphen (-)
and underline (_).  The tag name may be prefixed by a <a href="#groups">group name</a>
(separated by a colon) to identify a specific information type or location.  A
special tag name of "<code>All</code>" may be used to represent all tags, or all
tags in a specified group. For example:</p>

<blockquote><pre>
exiftool -filename -imagesize -exif:fnumber -xmp:all image.jpg
</pre></blockquote>

<p>A complete list of <a href="TagNames/index.html">ExifTool Tag Names</a>
accompanies this documentation.  As well, current lists of available tag names
and writable tag names may be obtained using the exiftool <code>-list</code> and
<code>-listw</code> options. But perhaps the easiest way to determine a tag name
is to use the <code>-s</code> option to print the tag names instead of
descriptions for all information in a file.  It may also be helpful to use the
<code>-G</code> option to display the group names, and the <code>-H</code> or
<code>-D</code> option to print the numerical tag ID's for reference.</p>

<p><b>Notes:</b></p>

<ol><li>Tag names sometimes differ from their descriptions.  Use the
<code>-s</code> command-line option to see the actual tag names instead of the
descriptions shown when extracting information.</li>
<li>When extracting information, tags will not appear in the output unless they
exist in the file, even if they are specified on the command line.  The
<code>-f</code> option may be used to force all specified tags to be displayed
(not including tags specified with wildcards or by <code>-GROUP:all</code>).</li>
<li>Information for a given tag name may occur in multiple locations within a
single file.  By default these duplicate tags are suppressed, but the <code>-a</code>
option may be used to extract all tags.</li>
<li>Tag names may be suffixed by a '<code>#</code>' character to disable the
print conversion on a per-tag basis.  See the
<a href="exiftool_pod.html#item_n">-n option</a> in the application
documentation for more information.</li>
</ol>

<h3><a name="shortcut">Shortcut Tags</a></h3>
<p>Shortcut tags represent one or more other tags, and are used like any other
tag when reading, writing or copying information.</p>

<p>ExifTool defines <a href="TagNames/Shortcuts.html">a few shortcut tags</a>
in the Image::ExifTool::Shortcuts module, and allows users to define their own
shortcuts in a <a href="config.html">configuration file</a> called
"<code>.ExifTool_config</code>" in their home directory or exiftool application
directory.  Here is a simple example that defines two shortcuts:</p>

<blockquote><table class=box><tr><td><pre class=blk>
%Image::ExifTool::UserDefined::Shortcuts = (
    MyShortcut =&gt; ['createdate','exposuretime','aperture'],
    MyAlias =&gt; 'FocalLengthIn35mmFormat',
);
</pre></td></tr></table></blockquote>

<p>In this example, MyShortcut is a shortcut for the CreateDate, ExposureTime
and Aperture tags, and MyAlias is a shortcut for FocalLengthIn35mmFormat.</p>

<p>The current shortcuts may be listed with the <code>-list</code> option.</p>

<p>The <code>~/.ExifTool_config</code> file may also be used to define new tags.
For more information about the configuration file, see the
<a href="config.html">sample configuration file</a> included with the ExifTool
distribution.</p>

<p><b>Windows tip:</b>  You may have difficulty generating a filename beginning
with a '<code>.</code>' in the Windows GUI, but it can be done with the
"<code>rename</code>" command at the cmd.exe prompt.</p>

<h2><a name="groups">Tag Groups</a></h2>

<p>ExifTool classifies tags into groups in various families.  Here is a list
of the group names in each family:</p>

<blockquote><table class=norm>

<p>The exiftool output can be organized based on these groups using the
<code>-g</code> or <code>-G</code> option (ie. <code>-g1</code> to see family 1
groups, or <code>-g3:1</code> to see both family 3 and family 1 group names in
the output.  See the <code>-g</code> option in the exiftool application
documentation for more details, and the <a href="ExifTool.html#GetGroup">GetGroup</a>
function in the ExifTool library for a description of the group families. Note
that when writing, only family 0, 1, 2 and 7 group names may be used.</p>

<h2><a name="writing">Writing Meta Information</a></h2>

<p>When writing information, ExifTool preserves the original file by adding
"<code>_original</code>" to the file name.  Be sure to keep a copy of the
original, or thoroughly validate the new file before erasing the original.
(<a href="writing.html">Read here</a> for some ramblings on the subject of
writing meta information.)</p>

<h3>Syntax</h3>

<p>Tag values are written rather than being extracted if any tag name ends with
a '<code>=</code>' symbol (or if the <code>-tagsFromFile</code> or
<code>-geotag</code> options are used).  The '<code>=</code>' may be prefixed by
'<code>+</code>', '<code>-</code>' or '<code>&lt;</code>' to add a value, remove
a value or set a value from file. The following table outlines the different
write syntaxes:</p>

<blockquote><table class=norm>
<tr><th>Syntax</th><th>Result</th></tr>
<tr><td>-TAG=</td><td>Deletes all occurrences of TAG</td></tr>
<tr><td>-all=</td><td>Deletes all meta information! <sup>&dagger;</sup></td></tr>
<tr><td>-GROUP:TAG=</td><td>Deletes TAG only in specified group</td></tr>
<tr><td>-GROUP:all=</td><td>Deletes all information in specified group</td></tr>
<tr><td>-[GROUP:]TAG=VALUE</td><td>Sets value of TAG (only in GROUP if specified)</td></tr>
<tr><td>-[GROUP:]TAG+=VALUE</td><td>Adds item to a list, shifts a date/time, or increments a number</td></tr>
<tr><td>-[GROUP:]TAG-=VALUE</td><td>Removes item from a list, shifts a date/time, or deletes TAG if it has the specified value</td></tr>
<tr><td>-[GROUP:]TAG&lt;=FILE</td><td>Sets tag value from contents of specified file</td></tr>
</table><sup>&dagger;</sup> See the <a href="#limitations">Writer Limitations</a> for some limitations of this feature.</blockquote>

<p>Quotes are required around VALUE if it contains spaces or other
special characters, and around the whole argument if the '<code>&lt;=</code>'
syntax is used (to prevent shell redirection).</p>

<p>A special feature allows the print conversion to be disabled on a per-tag
basis by suffixing any tag name (including '<code>all</code>') with the
'<code>#</code>' character.  This has the same effect as the
<code>-n</code> option, but for a single tag.  See the
<a href="exiftool_pod.html#item_n">-n option</a> in the application
documentation for more details.</p>

<p><b>Note:</b> Changes to PDF files are reversible because the original
metadata is never actually deleted from these files.  See the
<a href="TagNames/PDF.html">PDF Tags documentation</a> for details.</p>

<h3>Group Priorities</h3>

<p>ExifTool prioritizes the following types of meta information when writing:</p>

<blockquote>
<b>1)</b> EXIF, &nbsp; <b>2)</b> IPTC, &nbsp; <b>3)</b> XMP
</blockquote>

<p>Many tag names are valid for more than one of these groups.  If a group name is
not specified when writing information, then the information is added only to
the highest priority group for which the tag name is valid (however, the
information is updated in all groups where the tag already existed).  The
priority of the groups is given by the list above. Specifically, this means that
new information is added preferentially to the EXIF group, or to the IPTC group
if no corresponding EXIF tag exists, or finally to the XMP group.</p>

<p>Alternatively, information may be written to a specific group only, bypassing
these priorities, by providing a group name for the tag.  The
"<a href="#writing">Writing Meta Information</a>" section above gave the syntax
rules for exiftool command-line arguments to do this.  Any family 0, 1, 2 or 7 group
name may be used when writing information, although not all groups are writable.</p>

<h3>The "-tagsFromFile" Option</h3>

<p>A special ExifTool option allows copying tags from one file to another. The
command-line syntax for doing this is
"<code>-tagsFromFile <i>SRCFILE</i></code>".  Any tags specified after this
option on the command line are extracted from source file and written to the
destination file.  If no tags are specified, then all writable tags are copied.
This option is very simple, yet very powerful.  Depending on the formats of the
source and destination files, some of tags read may not be valid in the
destination file, in which case they aren't written.</p>

<p>This option may also be used to transfer information between different tags
within a single image or between different images.  See the
<a href="exiftool_pod.html#item__2dtagsfromfile_srcfile_or_fmt">-tagsFromFile
option</a> in the application documentation for more details.</p>

<h2><font color='#cc0000'><a name="limitations">Writer Limitations</a></font></h2>
<ul>
<li>ExifTool will <b>not rewrite a file if it detects a significant problem</b>
with the file format.</li>
<li>ExifTool has been tested with a wide range of different images, but since it
is not possible to test it with every known image type, <b>there is the possibility
that it will corrupt some files</b>.  Be sure to keep backups of your files.</li>
<li>Even though ExifTool does some validation of the information written, it is
still <b>possible to write illegal values</b> which may cause problems when
reading the images with other software.  So take care to validate the
information you are writing.</li>
<li>ExifTool is <b>not guaranteed to remove metadata completely</b> from a file
when attempting to delete all metadata. For JPEG images, all APP segments
(except <a href="TagNames/JPEG.html#Adobe">Adobe APP14</a>, which is not removed
by default) and trailers are removed which effectively removes all metadata, but
for other formats the results are less complete:
<ul>
<li>JPEG - APP segments (except <a href="TagNames/JPEG.html#Adobe">Adobe APP14</a>) and trailers are removed.</li>
<li>TIFF - XMP, IPTC, ICC_Profile and the ExifIFD are removed, but some EXIF may remain in IFD0. (The CommonIFD0
  <a href="#shortcut">Shortcut tag</a> is provided to simplify removal of common metadata tags from IFD0.)</li>
<li>PNG - Only XMP, EXIF, ICC_Profile and native PNG textual data chunks are removed.</li>
<li>PDF - The original metadata is never actually removed.</li>
<li>PS - Only XMP and some native PostScript tags may be deleted.</li>
<li>MOV/MP4 - Most top-level metadata is removed.</li>
<li>RAW formats - It is not recommended to remove all metadata from RAW images
because this will likely remove some proprietary information that is necessary
for proper rendering of the image.</li>

Some antivirus software has been known to cause problems for the <b>Windows</b>
version of ExifTool. <b>Norton Antivirus</b> may delete ExifTool when it is run,
<b>Windows Defender</b> may slow down launching of ExifTool or hang it altogether,
and <b>Bitdefender Antivirus</b> may block ExifTool from writing files.
Presumably this is due to the way the ExifTool package for Windows works -- it
unpacks executable files into a temporary directory and runs from there, which
apparently may be seen as a threat by antivirus software.  A work-around is to
add ExifTool to the exclusion list of the antivirus software.</li>

<h2><font color='#cc6600'><a name="security">Security Issues</a></font></h2>
<p>Some ExifTool options (<code>-config</code>, <code>-if</code>,
<code>-p</code>, <code>-fileNUM</code>, <code>-api filter</code>,
<code>-api filterw</code> and copying arguments like <code>"-DSTTAG&lt;STR"</code>)
have the ability to execute Perl code from external files or within command-line
arguments.  This may be a security problem if ExifTool is executed from another
application that blindly passes untrusted file names on the command line (since
they may be interpreted as ExifTool options if they begin with a dash).  To be
secure the calling application must either place file names after the
"<code>--</code>" option, or ensure that input file names do not start with a
dash (U+002D) or a Unicode minus sign (U+2212).  One way to accomplish this is
to prefix input file names with a known directory name, eg.)
<code>"./FILENAME"</code>.</p> <p>As well, untrusted window title strings should
not be used with the <code>-progress:TITLE</code> option.</p>

<h2><a name="shift">Date/Time Shift Feature</a></h2>

<p>Have you ever forgotten to set the date/time on your digital camera before
taking a bunch of pictures?  ExifTool has a time shift feature that makes it
easy to apply a batch fix to the timestamps of the images (eg. change the "Date
Picture Taken" reported by Windows Explorer).  Say for example that your camera
clock was reset to 2000:01:01&nbsp;00:00:00 when you put in a new battery at
2005:11:03&nbsp;10:48:00.  Then all of the pictures you took subsequently have
timestamps that are wrong by 5 years, 10 months, 2 days, 10 hours and 48
minutes.  To fix this, put all of the images in the same directory
(<i>"<code>DIR</code>"</i>) and run exiftool:</p>

<blockquote><pre>
exiftool "-DateTimeOriginal+=5:10:2 10:48:0" <i>DIR</i>
</pre></blockquote>

<p>The example above changes only the DateTimeOriginal tag, but any writable date
or time tag can be shifted, and multiple tags may be written with a single
command line.  Commonly, in JPEG images, the DateTimeOriginal, CreateDate and
ModifyDate values must all be changed.  For convenience, a
<a href="#shortcut">Shortcut tag</a> called <b>AllDates</b> has been defined to
represent these three tags.  So, for example, if you forgot to set your camera
clock back 1 hour at the end of daylight savings time in the fall, you can fix
the images with:</p>

<blockquote><pre>
exiftool -AllDates-=1 <i>DIR</i>
</pre></blockquote>

<p>See
<a href="Shift.html">Image::ExifTool::Shift.pl</a>
(<a href="https://exiftool.org/Shift.pdf">download in PDF format</a>)
for details about the syntax of the time shift string.</p>

<p><b>Note:</b> Not all date/time information is covered by the AllDates
shortcut. Specifically, the filesystem date/time tags are not included, and this
command will reset FileModifyDate to the current date/time as it should when the
file is modified, unless either the <code>-P</code> option is used, or
FileModifyDate is set to something else.  To shift FileModifyDate along with the
other tags, add <code>-FileModifyDate-=1</code> to the command above.</p>

<h2><a name="filename">Renaming and/or Moving Files</a></h2>

<p>By writing a new value to the <b>FileName</b> and/or <b>Directory</b> tags,
files can be renamed and/or moved to different directories.  This can be a very
powerful tool in combination with the <code>-d</code> (date format) option for
organizing images by date/time. For example, the following command renames all
images in directory <i>"<code>DIR</code>"</i> according to the individual file's
creation date in the form "<code>YYYYmmdd_HHMMSS.ext</code>".</p>

<blockquote><pre>
exiftool "-FileName&lt;CreateDate" -d "%Y%m%d_%H%M%S.%%e" <i>DIR</i>
</pre></blockquote>

<p>Or a new directory can be specified by setting the value of the <b>Directory</b>
tag.  For example, the following command moves all images originally in
directory <i>"<code>DIR</code>"</i> into a directory hierarchy organized by
year/month/day:</p>

<blockquote><pre>
exiftool "-Directory&lt;DateTimeOriginal" -d "%Y/%m/%d" <i>DIR</i>
</pre></blockquote>

<p><a href="filename.html">Read here</a> for more details about this powerful
feature.</p>

<h2><a name="performance">Improving Performance</a></h2>

<p>There is a significant overhead in loading ExifTool, so performance may be
greatly improved by taking advantage of ExifTool's <b>batch processing capabilities</b>
(the ability to process multiple files or entire directories with a single
command) to reduce the number of executed commands when performing complex
operations or processing multiple files.<span class=sm><sup>&dagger;</sup></span>
<i>[One exiftool user
<!-- dead link <a href="https://web.archive.org/web/20131204165247/http://www.christian-etter.de/?p=458"> -->
documented a 60x speed increase<!-- </a> --> by processing a large number of files with a single
command instead of running exiftool separately on each file.]</i> Also, the
<code>-execute</code> option may be used to perform multiple independent
operations with a single invocation of exiftool, and together with the
<code>-stay_open</code> option provides a method for calling applications to
<b>avoid this startup overhead</b>.</p>

<p>It has also been observed that the loading time of ExifTool for Windows
increases significantly when Windows Defender is active.  <b>Disabling Windows
Defender</b> may speed things up significantly.</p>

<p>The processing speed of ExifTool can be improved when extracting information
by reducing the amount of work that it must do.  Decrease the number of
extracted tags by specifying desired tags individually (<code>-TAG</code>) or by
group (<code>-GROUP:all</code>), and disable the composite tags (<code>-e</code>)
and the print conversions (<code>-n</code>) if these features aren't required. 
Note that the exclude options (<code>-x</code> or <code>--TAG</code>) are not
very efficient, and may have a negative impact on performance if a large number
of tags are excluded individually.  The exception is XMP groups, which are
bypassed in processing so they are never even extracted -- specifying
<code>--XMP-crs:all</code> and <code>-XMP-crd:all</code> may speed processing
significantly by avoiding processing of bulky Adobe image-editing information.
The <a href="ExifTool.html#IgnoreTags">API IgnoreTags option</a> (added in
ExifTool 12.43) may also be used for significant speed benefits in some cases.</p>

<p>The <code>-fast</code> option can significantly increase speed when
extracting information from JPEG images which are piped across a slow network
connection.  However, with this option any information in a JPEG trailer is not
extracted.  For more substantial speed benefits, <code>-fast2</code> may be
used to also avoid extracting MakerNote information if this is not required,
or <code>-fast4</code> if only pseudo System tags are required.</p>

<p>When writing, avoid copying tags (with <code>-tagsFromFile</code>) or using
the <code>-if</code> or <code>-fileOrder</code> option because these will add
the extra step of extracting tags from the file.  Without these the write
operation is accomplished with a single pass of each file.</p>

<blockquote><span class=sm><sup>&dagger;</sup></span> <span class=lt>However,
note that when the <code>-csv</code> option is used, information from all files
is buffered in memory before the CSV output is written.  This may be very memory
intensive and result in poor performance when reading a large number of files in
a single command.</span></blockquote>

<h2><a name="library">The Image::ExifTool Perl Library Module</a></h2>

<p>The "<code>exiftool</code>" script provides a command-line interface to the
Image::ExifTool Perl library module which is part of the ExifTool distribution.
The Image::ExifTool module can be used in any Perl script to provide easy access
to meta information.  Here is an example of a very simple script that uses
Image::ExifTool to print out all recognized meta information in a file:</p>

<blockquote><table class=box><tr><td><pre class=blk>
<span class=com>#!/usr/bin/perl -w</span>
use Image::ExifTool ':Public';
my $file = shift or die "Please specify filename";
my $info = <a href="ExifTool.html#ImageInfo">ImageInfo</a>($file);
foreach (keys %$info) {
    print "$_ : $info-&gt;{$_}\n";
}
</pre></td></tr></table></blockquote>

<p>Note that some tag values may be returned as SCALAR references indicating
binary data.  The simple script above does not handle this case.</p>

<p>See the <a href="ExifTool.html">Image::ExifTool Documentation</a> for more details.</p>

<p>There is still much unknown information in the maker notes for many camera
models.  (To see this information, run exiftool with the <code>-U</code>
option.)  In this area, ExifTool is very much a collaborative effort, and
development relies heavily on the input from camera owners to help decode new
meta information.  If you manage to figure out what any of it means, send me an
e-mail (philharvey66 at gmail.com) and I'll <b>add your new discoveries to
ExifTool</b>.  Many thanks to all who have helped so far...</p>

<h2><a name="background">Phil's Background</a></h2>

<p>Phil has a master's degree in nuclear physics and is now officially retired
from his position at Queen's University where he worked with the Nobel-prize-winning
<a href="https://sno.phy.queensu.ca">Sudbury Neutrino Observatory</a> (SNO) team
and other SNOLab experiments from 1990 to 2020.  For SNO he wrote the software
to aquire, format, store and display all of the hundreds of terabytes of data
generated by the detector; software that continues to be used by
<a href="https://snoplus.phy.queensu.ca">SNO+</a> for their even greater data
volume.</p>

<p>ExifTool started as a simple utility used to display metadata from
images hosted on the SNO web site, but quickly expanded in scope as Phil got
involved with digital photography beginning in 2001.  During retirement Phil
continues to enjoy digital photography, a hobby which he now applies to bird
watching. A selection of his birding pictures may be found in his recent
<a href="https://www.blurb.ca/b/11481065-birds-of-kingston">Birds of Kingston</a>
book.</p>
