Need help with Emulsa? Email emulsa@jeffersondavis.us. Please include your Mac model, macOS version, scanner model and a short description of what happened. A screenshot helps too.
Supported scanners
- Epson Perfection V series (V19 to V850) with Epson Scan 2 or Epson’s Mac scanner driver installed
- Canon CanoScan film scanners (8400F, 8600F, 8800F, 9000F and 9000F Mark II) and LiDE flatbeds, with Canon’s Mac scanner driver installed
Getting started
- Install your scanner maker’s Mac driver and connect the scanner by USB.
- Open Emulsa and select your scanner in the sidebar.
- Choose Negatives, Slides or Flatbed, and pick the film format (35mm, 6×4.5, 6×6, 6×7, 6×9 or 4×5).
- Press Preview. Emulsa finds each frame automatically. Drag a box to adjust it, or draw a new one.
- Switch to Positive to check the frames, then press Scan. Files are saved as 16-bit TIFFs in your chosen folder.
Common questions
My scanner doesn’t appear.
Make sure the maker’s Mac driver is installed and the scanner is on and connected. If it doesn’t show up in Apple’s Image Capture app either, the driver isn’t installed or doesn’t support your version of macOS.
Emulsa asked to access my scanner.
That’s macOS asking permission. Click Allow. You can change it later in System Settings → Privacy & Security.
A frame was cropped wrong or missed.
In the Negative view, drag the box to move it, drag a corner to resize it, or drag on empty film to draw a new one. Right-click a box to delete it or to detect frames again.
The colors look off.
Pick the film stock you shot, then fine-tune with Temperature, Saturation and Exposure. Film stock settings are starting points.
Can I try Emulsa without a scanner?
Yes. Choose “Demo Scanner” in the sidebar.
Where are my scans?
In the folder shown under Output → Folder. Click “Show in Finder” after a scan to jump to the file.
