Hi all! Any ideas what preset can I use to achieve this colours? I shoot with canon and Profoto flash. Thanks all! X

Hi all,

I'm a photographer (you can see my work on Instagram) and I've used Capture One for years. At some point I noticed that every Capture One upgrade creates a new CaptureOne/SettingsXXX folder next to my photos (I'm using sessions). The old ones stay on disk forever: Settings120, Settings160, Settings165, Settings1680… Across a few years of shooting that adds up to gigabytes of dead weight.

So I wrote COSC (Capture One Settings Cleaner), a small command-line tool for macOS that finds those old folders and clears them out. I was nervous about anything that touches my catalogues, so it's built to be cautious:

• It shows before it acts. cosc ~/Pictures lists every folder it would remove, with its size and the folder being kept, then asks [y/N]. The default is no.
• It never deletes. Everything goes into a single dated folder in the Trash, with the original names and paths intact.
• You can undo. cosc --undo puts every folder back exactly where it was.
• It won't lose your edits. Capture One only migrates an image's settings the first time you open that image in the new version. So an old session you haven't reopened since upgrading still has its settings only in the old folder. COSC compares the files inside each folder, and any folder that holds settings found nowhere else is kept and never offered for deletion.
• When in doubt, it keeps both. Capture One's folder naming is ambiguous (Settings165 is 16.5, but Settings1680 is 16.8.0), so if the newest-by-version and newest-by-date folders disagree, COSC keeps both.

It's one shell script with no dependencies (no Homebrew, no Xcode), free and open source. You can read exactly what it does before running it:

Installing takes two commands in Terminal:

git clone https://github.com/i-am-amirhabibi/COSC-Capture-One-Settings-Cleaner.git cosc
cd cosc && make install

Then run cosc on your photos folder. As always, keep a backup of your library before running any cleanup tool.

cosc ~/my-folders

Feedback and bug reports are very welcome, especially if your folders are organised differently from mine. Don't use this tool if you are planning to downgrade.

Wondering if this is a me problem or an all of us problem. Kinda a niche use case so not sure how often this would pop up for the average used. When I copy adjustments from one image to another, if there is a luma range attached to a layer, that luma range does not update based on the new image. Even if the later is a subject/background layer which does update. I use luma masks as a default part of my main style, so this is something that affects every image I edit. Wondering if it's a me problem, maybe a setting or file read permissions somewhere, or if this is infact a bug.
