ExifTool is written in Perl, so if you are on windows you need to install Perl before installing exifr (easily done from Strawberry Perl: 64-Bit (most users), 32-Bit (advanced)). Mac and linux users already have this installed. To install the {exifr} package, use the devtools::install_github() command like this:

install.packages("devtools") # if you don't already have devtools installed
