Reflection and Transmission Densitometer for Photographic Darkroom Use
Printalyzer Densitometer
Introduction
The Printalyzer Densitometer is a project whose goal is the creation of an
affordable reflection and transmission densitometer for photographic darkroom
use.
It was initially conceived as an accessory to complement the
Printalyzer Enlarging Timer & Exposure Meter
to ease the process of creating paper profiles. However, given the general
utility of such a device, it has been spun off as a separate project in its
own right.
A good overview of the project can be found in these blog posts:
This project, using hardware tagged as “Revision C” and labeled as DPD-100, is currently shipping as an official Dektronics product. Links to the user manual and regulatory compliance documents can be found on the product website.
Project Layout
Hardware
The “hardware” directory contains KiCad projects
with the complete circuit schematics, bill-of-materials, and
PCB layouts.
Software
The “software” directory contains all the source code for the firmware
that runs on the hardware.
Enclosure
The “enclosure” directory contains any CAD models and related resources
necessary to physically assemble the device.
License
Individual directories will contain LICENSE files as needed, with relevant
details. Generally, the hardware will be CC BY-SA and the software will be
BSD 3-Clause. However, external resources may have their own individual license terms.
