Getting Started

PPRC batch-converts Pakon F135/F135+ planar raw files into full 16-bit TIFFs with the orange mask removed, giving you the highest-quality starting point for your editing workflow.

Prerequisites

You'll need Node.js installed (v22 or later; v22 has significant performance improvements over earlier versions).

Install

Install PPRC globally via npm:

npm i -g pakon-planar-raw-converter --foreground-scripts

The --foreground-scripts flag lets PPRC show a welcome message after install, but isn't strictly necessary.

Quick start

First, open a terminal:

• Mac: Press CMD+Space, type "terminal", hit Return
• Windows: Open the Start menu, search for "cmd", and run it

Then navigate to your folder of .raw files. The easiest way is to type cd (with a space) and then drag the folder from Finder or Explorer into the terminal window. Press Enter, then run:

pprc

Processed files will be saved to an out/ subdirectory.

For best color consistency, process a whole roll together when possible. PPRC's default inversion analyzes the batch as a group, which helps keep results consistent across frames and makes outlier-frame rejection more reliable.

macOS Finder Quick Action

On macOS, run pprc --install-quick-action to add a Finder Quick Action. You can then right-click any folder of raw files and select "Process with PPRC", no terminal needed.

Updating

PPRC will notify you when a new version is available. You can update at any time:

npm update -g pakon-planar-raw-converter --foreground-scripts

Windows XP Note

Please do not try to run PPRC on Windows XP. Everything will be easier and faster if you install on a more modern OS. There is no need to run PPRC from the computer you scanned on.
