I tried using Lightroom. I would copy the settings from one photo and paste them to the next, then adjust it, and repeat. This was very slow. If I used a simple batch edit on all photos, it looked bad because the lighting changed in every shot. After 40 minutes, I was not even halfway done. I had to choose between bad quality batch edits or fixing 2K photos one by one.
I also did not want to upload my private wedding photos to a website or pay for a monthly subscription.
I wanted a way to edit fast but still have control over each photo. I also wanted everything to stay private on my computer.
So I built a Mac app called RapidPhoto.
It lets you set the look once and apply it to the whole wedding set. The important part is that you can still quickly tweak individual photos that look a bit different without starting over. I also added a feature to change the metadata for many photos at once, which is helpful for organizing big events.
The work that took me 40 minutes now takes about 90 seconds. It runs locally on your Mac with no uploads and there is no subscription.

Browsing forgotten 2000s digicam photos from Flickr before smartphones took over everything.
HDR/EDR video grading on macOS, but explicitly not daily-driver ready yet.
Folder-native manifests plus a global SQLite index let you keep originals untouched while getting album features and very fast queries — smart trade-offs for large local libraries. Live Photo pairing/playback, a map view, and GPU-accelerated browsing show real engineering focus; it's not reinventing the genre (digiKam/Lightroom exist), but this is a tidy Photos-to-Windows port with thoughtful implementation details.
Fast, native batch tooling with sensible features — apply crops across 100 images, 14 pro aspect ratios, real‑time previews and exports to modern targets like WebP and AVIF while keeping processing on‑device. It’s practical and privacy‑minded, but the category is crowded (Lightroom, ImageMagick, shortlists of GUI tools) and there’s nothing here that feels radically new beyond a tidy macOS UI and export format support.
Polished UI wrapping standard generative video models for real estate.
