MetaMFix::  A Batch Processing Utility For Image Files, Replace Incorrect Nikon EXIF f/0.0 or f/1.0 MaxApertureValue Metadata With Correct Manual Focus Lens Maximum Aperture, and Lens Metadata
 utilizing Phil Harvey's ExifTool on the Windows platform.
 
MetaMFix::
 
MetaMFix:: is a simple dialog utility that assists in easily adjusting metadata for any image file(s) in a selected folder when a image file contains a EXIF MaxApertureValue = f/0.0 or f/1.0.
 
MetaMFix will open all image files in a selected folder (of a selected file type), in order to initially identify, and then later adjust any incorrectly labeled MaxApertureValue f/0.0 or f/1.0 metadata values.
 
It replaces the incorrect metadata with a correct Max Aperture value that is obtained for a lens from the custom user modified Lens Information (a csv formatted) text file: MyNikonLenses.txt.
 
It will write the revised camera lens metadata into the image files by using Phil Harvey's ExifTool run in a series of background processes.
 
Go From Incorrect Lens MetaData:

 
as seen here for the Incorrectly Labeled Camera MetaData Fields:
  • Lens = ?
     
  • Lens Max Aperture Value = f/1.0
     
 
To Corrected Lens Data:
 
MetaMFix:: will run Phil Harvey's ExifTool by first checking a digital image for correct camera lens data parameters, and updating any incorrect lens metadata to a image file.
 
To Update to a Current Version of ExifTool:
  
Download the current Windows executable version of Exiftool from his web page here.
Extract the standalone Windows executable, rename it to 'exiftool.exe' and place it in the MetaMFix program file directory.
  
Resulting In This:
 
An example of updated MetaMFix:: lens data in the image metadata tags as seen in Adobe Bridge CS4:
 
  

for the Camera MetaData Fields:
  • Lens
     
  • Lens Max Aperture Value
     
(Available & Written Metadata fields are dependant on the original image's
Nikon makernotes and exif metadata, and the user's lens data csv file.)
