1. Open Flashback-macOS.dmg

2. Drag Flashback One35 into your Applications folder

3. On first launch, macOS will block the app because it isn't signed. To open it:

   • Double-click the app — macOS will show a warning and refuse to open it
   • Go to System Settings → Privacy & Security
   • Scroll down — you'll see "Flashback One35 v2 was blocked"
   • Click Open Anyway and confirm

   You only need to do this once.

1. Run Flashback-Windows-Setup.exe
2. If SmartScreen shows "Windows protected your PC" (the app is not yet code-signed):
   • Click More info
   • Click Run anyway
3. Follow the installer — it will create a Start Menu entry and optional desktop shortcut

1. Download Flashback-Linux.AppImage
2. Make it executable and run:

   chmod +x Flashback-Linux.AppImage
   ./Flashback-Linux.AppImage
   

3. If you get a FUSE error, either install it (sudo apt install libfuse2) or extract and run directly:

   ./Flashback-Linux.AppImage --appimage-extract
   ./squashfs-root/AppRun
   

• Custom color pipeline — sensor-specific CCM, white balance, and LUT tuned for the One35 v2
• Film emulation effects — halation, chromatic aberration, softness, and grain
• Batch export — queue and process multiple images to JPEG in one go
• Zen mode — hide controls for a clean full-screen view of your image
• Drag & drop — drop DNG files or folders directly onto the app
• Camera detection — auto-detects the One35 v2 when connected via USB

2. Browse images in the thumbnail strip at the bottom
3. Adjust Exposure, White Balance, and Tint with the sliders
4. Set your export folder and click Process to export JPEGs
5. Alternatively export 16-bit tif-intermediates to quickly reprocess later
