Writing a Lightroom Classic plug-in

As part of my migration to Lightroom Classic from Photos, I needed to recreate my folder and album structure. In Photos, folders container albums (or other folders) and albums contain photos. An album cannot contain a folder. This maps directly to Lightroom Classic which has "collection sets" for folders and "collections" for albums. To transfer the folder and album information over to Lightroom Classic, I wrote an Apple Script for Photos that added a keyword… continue reading.

Migrating to Lightroom Classic from Apple Photos

I recently moved over to Adobe's Lightroom Classic from Apple's Photos in order to have more flexible non-destructive editing features – in particular local brushes. Rather confusingly, there's also another Adobe product called Lightroom which is a new build for cloud-based storage which doesn't (yet?) have all the features of Lightroom Classic. In particular, the lack of virtual copies and smart collection sets make Lightroom feel like a step backwards from Photos, while Lightroom Classic… continue reading.

Setting title and caption with exiftool

I recently needed to change the title and caption of some photos, so I turned to exiftool as it's the Swiss Army knife of image metadata.

It's a lovely tool with many options, so I wrote a script to make it easy and while I was there, used read to prompt me for the info to set. This is the script:

Analysing the focal length of my photos

I'm currently thinking about upgrading my camera to an EOS R or Z6 and, as result, I'm thinking about which lenses I should get. While discussing options with Stuart, I wondered which were my favourite focal lengths for the photos that I've taken in the past. To work this out, I decided to use the wonderful exiftool and some scripting. This is the analyse.sh script:

#!/bin/bash

DIR="$1"

if [ "$DIR" == "" ]; then
    echo "Usage: analyse.sh {directory}"
    exit
fi

exiftool -r -T -focallengthin35mmformat -aperture -lens -ext NEF -ext ARW $DIR > analysis.txt

awk '{print $1, $2}' analysis.txt | sort | uniq -c | \
    awk 'BEGIN { OFS = ", " } ; {print $2 $3, $1}' | \
    sort -n > analysis.csv

echo -e "\"Focal length\",count\n$(cat analysis.csv)" > analysis.csv

echo "Created analysis.csv"

awk '{print $1, $2}' analysis.txt | sort | uniq -c | \

awk 'BEGIN { OFS = ", " } ; {print $2 $3, $1}' | \

sort -n > analysis.csv

echo -e "\"Focal length\",count\n$(cat analysis.csv)" > analysis.csv

echo "Created analysis.csv"

There's a couple of key things going on here.… continue reading.
