Hello!
RawCull is a macOS app for culling RAW files fast — built by one developer who needed a better way to sort through thousands of ARW files after a day in the field.
Got ideas, feedback, or a bug to report? I’d love to hear from you at thomeven@gmail.com.
Background
I started RsyncOSX in August 2016 as a way to learn Swift. After eight years of releases, it was archived in August 2024. RsyncUI, built with SwiftUI, began in late 2020 and is still actively developed. RawCull is my latest project — a fresh take on building focused macOS apps with modern Swift.
I hold a master’s degree in computing science, earned in the early 1990s, back when Linux and the public Internet were just emerging (the Web itself had been invented only a few years earlier, in 1989 at CERN). I’m a solo developer, not a professional UI designer, so I lean heavily on user feedback to shape the interface.
I retired in May 2022 at age 62. Outside of code, I’m an avid bird photographer who spends a lot of time in the Norwegian mountains. Grandchildren, photography, and cross-country skiing round out life alongside the coding projects.
Why RawCull exists
Since late 2020 I’ve been building RsyncUI, now in maintenance mode. As a photographer, I needed a fast way to cull ARW files from my Sony A1 Mk II after coming home with several thousand shots from a single outing. That itch — combined with a project idea I’d been sitting on for a while — is what became RawCull.
Development approach
Most of my career was spent in IT management rather than hands-on development. What coding experience I have comes from personal projects — RawCull, RsyncUI, and RsyncOSX. Along the way I’ve learned a lot from AI tools, documentation, and studying how other developers solve problems.
Build & distribution
RawCull is built with Swift and SwiftUI, using modern macOS APIs. It’s digitally signed and notarized by Apple, so you can trust it hasn’t been tampered with and meets Apple’s security standards.
