Mac
Negative Converter turns scanned film negatives into finished positives, entirely on your Mac. No uploads, no watermarks, no account.
Built for photographers who scan their own film, whether with a dedicated film scanner, a flatbed, or a digital camera on a light table.
CONVERT ANY NEGATIVE
• Color C41 negatives, black-and-white negatives, and positive slides
• Orange mask handling: sample the film base by hand, auto-detect it, or reuse one reference frame for a whole roll
• 37 film profiles modeled on classic color and black-and-white stocks
• Lab-style color renderings, including Frontier and Noritsu looks
WORKS WITH YOUR FILES
• RAW: CR2, NEF, ARW, DNG, RW2, and iPhone ProRaw
• 16-bit PNG and TIFF, for the full tonal range of your scan
• Ordinary JPEG and PNG scans
• Export to PNG, TIFF, or JPEG at 8-bit or 16-bit
FINE CONTROL WHEN YOU WANT IT
• Per-channel RGB gain, CMY balance, and editable tone curves
• Exposure, contrast, vibrance, saturation, temperature, and tint
• Gray-point white balance sampling
• Unsharp masking and dust removal
• Automatic frame detection, cropping, and rotation
BUILT FOR ROLLS, NOT JUST FRAMES
• Open a whole folder of scans at once
• Dial in one frame, then apply those settings to every frame you select
• Export the entire batch in a single pass
FILM EDGE RENDERING
Add sprocket holes, frame numbers, DX edge codes, and film stock lettering to recreate the look of a full-frame scan.
