Script to find and Delete JPEGs form RAW+JPEG Pairs


The other day, a friend of mine trying to free up some space on their computer asked me if I knew how to delete the JPEGs from a RAW+JPEG pair in Lightroom. After scratching my head on that for a while, I threw together a Powershell script to do the job, and so I’m sharing it here in the event it might be helpful for someone else.

WARNING: Advanced computer stuff ahead.

This script is for Windows and requires Microsoft’s Powershell environment to execute. I’ve tested it in Powershell version 3 on Windows 7. If you don’t have Powershell installed, the latest version can be downloaded from Microsoft.

To run the script, place it in the top-level directory of the directory tree where you want it to scan; right-click on it and choose “Run in Powershell.” The script will prompt you before running whether you want to just build a list of files to remove or delete them. I recommend not deleting files on the first pass, just to be safe as the deletions done by this script aren’t reversible.

The script considers a JPEG to be part of a RAW+JPEG pair when the files have the same name but a different extension (.nef, .cr2, or .dng for raw, and .jpg for JPEGs), and exist in the same directory. The script recursively scans through every child directory starting from the directory the script is executed from looking for RAW+JPEG pairs.

Results are always logged to raw&jpeg.log in the same directory as the script itself.

Due to the nature of the process, the script can take some time to run, and doesn’t display progress unless it finds matches.

I recommend running the script and verifying that the files it’s selected to delete are in fact RAW+JPEG pairs, before deleting them.

Radio Trigger Roundup

January 2014 Edition

When I first started with Radio Triggers you had basically two options, some cheap modules of questionable reliability that were marketed under a number of brands, and LPA Design’s Pocket Wizards. That was a scant 5 years ago, and since then the radio trigger marketplace has changed dramatically. Pocket Wizards, while still the Cadillac of radio triggers, have had their reliability and capabilities matched and in some cases beaten. In short, the question of which triggers are best has become considerably more complicated.

The simple reality is that there is now a massive number of competing radio trigger products on the market in every product space. The entry-level market, for example, is awash in similar products from various brands that have little if anything to differentiate them from each other. Almost all of the studio strobe makers have joined in the radio trigger market, producing triggers designed primarily to provide users of that manufactures strobes with remote power control and cordless triggering; though many of these systems also have generic modules available. TTL systems have become more commonplace, with a range of products from inexpensive designs to fully featured and integrated ones.

My intent here isn’t to recommend a product. What I use and what I need aren’t what you use or you need, and my solutions aren’t necessarily your solutions. Instead, what I’ve tried to do is cover most of the available systems and the pros and cons as I see them. You then can use this as a launching point to dig further into the solutions you find best fit your needs.
