rem File:         lr-datetime-equalize.bat
rem
rem Description:  Microsoft Windows batch file calling exiftool and exiftool arguments file. Process equalizes 
rem               date/time metadata across all relevant JPG, CR2 and XMP file metadata fields.
rem
rem Purpose:      To match all date/time metadata fields to the same date/time value. 
rem
rem Reason:       Many photo organizing and editing tools allow the change of one or more date/time
rem               metadata fields. Doing so leaves the photo file(s) with some date/time fields that
rem               do not match. Different photo geotagging, organizing and editing tools, as well as 
rem               photo hosting web sites, use different date/time metadata fields to establish 
rem               the date/time for the photo. This can cause many problems related to geolocation, 
rem               photo sorting, photo display order, etc. By equalizing, or matching, the date/time
rem               information across all metadata date/time fields, the photos will be treated 
rem               processed, displayed, etc. the same by all photo tools and web sites. 
rem      
rem
rem Usage:        1. Using Windows Explorer or a command line, place this batch file and the 
rem                  lr-datetime-equalize.args in the folder/directory with the photos you wish to process
rem                  
rem               2. Using Windows Explorer or a command line, execute the batch file. 
rem                     -Windows Explorer: double click the lr-datetime-equalize.bat file
rem                     -command line: lr-datetime-equalize.bat

rem     Notes:
rem    	  * This batch file processes all xmp, cr2 and jpg files in a directory and its subdirectories.
rem
rem	  * This batch file requires the parameter file lr-datetime-equalize.args for data field mapping.
rem
rem	  * Put this batch file and the lr-datetime-equalize.args file in the directory with the files you 
rem         wish to process.
rem
rem       * This batch file processes Canon CR2 (RAW) files first, then JPG files.
rem
rem       * If you wish to use this utility for non-Canon RAW files, edit the file name extension CR2 and cr2 
rem         below to your applicable RAW filetype extension, e.g., NEF.
rem
rem       * To see more detail about the operations performed, add a -v to the exiftool command lines below. 
rem         The level of detail increases with each of the following increments of the variable: 
rem         -v, -v0, -v1, -v2, -v3, -v4, -v5
rem
rem	  * This batch file requires an installed copy of ExifTool by Phil Harvey.
rem
rem	  * Download the ExifTool windows command line version and rename the file exiftool.exe. 
rem
rem	  * Place the exiftool.exe file in your windows directory or on your system path.

echo+
echo Why? After running this utility, when you display, sort or geolocate your 
echo photos by date, they will always display, sort and geolocate the same - 
echo regardless of the tool, system or web site you are using.
echo+
echo This utility sets all date/time metadata fields to match the master 
echo XMP-xmp:CreateDate date/time metadata field.
echo+ 
echo This utility processes photo files in the current folder and its subfolders.
echo The current folder is: %CURRENTDIR%
echo+
echo All relevent date/time metadata fields are matched/equalized/synchronized 
echo in all JPG, XMP and CR2 files.  
echo+
echo This utility is optimized for use with photo files whose capture time was 
echo edited with Adobe Lightroom. Photo files edited with other programs may 
echo require you to edit the date/time master to target field mapping. Metadata 
echo date/time master to target field mapping is controlled by the file 
echo lr-datetime-equalize.args.
echo+
echo This utility is optimized for use with Canon photo files. Other 
echo manufacturers' photo files may require editing the photo file extension type.
echo Photo file extension type, e.g. .CR2 vs .NEF, is controlled by this 
echo batch file.
echo+
echo This utility requires the free exiftool program by Phil Harvey.
