Windows drag n drop Batch Image Metadata Updates

Batch modifying the exif metadata on your images (NEF, DNGs, jpegs ....) in Windows can be a little painful. Exiftool is a great tool that can perform the metadata updates but most would associate this with command line updates.

With Windows, there exists a neat tick with batch files that you can drag and drop files onto batch file under Windows explorer and the batch file will accept them as arguments. For example, to set the lens information on any exiftool support file, create the following .bat file and then drag and drop your files!

@echo off FOR %%i IN (%*) DO exiftool -overwrite_original -Lens="Nikkor 20mm f/3.5 AI" -MaxApertureValue="3.5" -FocalLength="20" %%i pause

Overcoming missing DisplayCAL dependacies on recent Linux distros with X11 container

DisplayCAL has been a great free tool to partner your hardware colour calibrator, like your DataColor Spyder etc. However installing this on any of the newer mid-2020 distributions (like Fedora 32 and above) has become problematic due to the python 2 requirements being dropped by a number of distributions.

How can we continue to use your DataColor Spyder with DisplayCAL on a recent linux?
