Here is a small script to use Image Magick tools on the JPEG files from your camera, and create “smaller” versions in a new sub-folder called “smaller”.
It must be changed to match the JPG files produced by your camera. It looks for JPEG files with specific dimensions.
And of course this version only works on Unix-like systems that have the “bash” shell available.
#!/bin/bash rm -f list.txt mkdir smaller echo List of JPG files for a in P*.JPG; do (identify $a >>list.txt); done echo convert 4032x2272 images for a in $(grep -e "2272" list.txt | sed -re "s/^([^ ]+).*/\1/"); do (convert $a -comment "Copyright Robert Echlin. Larger version available." -resize 1920x1080 smaller/$a ); done echo convert 4032x3024 images for a in $(grep -e "3024" list.txt | sed -re "s/^([^ ]+).*/\1/"); do (convert $a -comment "Copyright Robert Echlin. Larger version available." -resize 1600x1200 smaller/$a ); done echo checking ... echo Local files ls *JPG | wc -l echo smaller files ls smaller | wc -l
