The Problem with Existing Film Tanks If you develop film in a darkroom, you know the frustration: almost every tank on the market leaks chemicals from the top when inverted. Paterson, AP, and most other systems all have this issue. The only exception is Jobo — but it comes at a cost. Inversion agitation is inconvenient, messy, and completely incompatible with automated film development setups where precise chemical dosing matters. ...

Open Hardware Reels: A Better Way to Develop Film I have designed a new type of open-source film developing reel specifically optimized for 3D printing. While many designs exist online, most are not tailored for home manufacturing, leading to failed prints or poor functionality. These reels are fully compatible with the standard systems like Paterson system and can be printed at home using common materials like PETG without supports and from two pieces. ...

Purpose The tool allows users to wind standard 35mm film into 120 backing paper. This enables shooting 35mm film in medium format cameras to achieve a wide-angle, panoramic effect that includes the film sprockets. Design and Materials The main body parts are 3D-printed using PLA for stiffness. Functional components like the lock/brake and shaft are printed from PETG to provide necessary flexibility and prevent cracking. The assembly is screwless, relying on friction fits and snapping mechanisms. ...

For Panterla’s loaded drum, the first prototype is a NEMA 17 stepper with the existing TMC2209, a direct connection, and independent drum-motion sensing. Here’s why a servo isn’t automatically quieter, why torque headlines can’t be compared, and what the loaded test needs to decide.

The JOBO CPE2 produced locally steady readings, but different locations did not converge. The transfer test adds the process question: warm liquid entered the rotating drum, then its measured temperature fell. What this means for preheat, circulation, and Panterla’s readiness criteria.

The corrected bath-corner readings were locally steady, but the bottle was still warming. The teardown also exposed wet-area wiring problems and identified the installed controller as WH1435A. Small temperature variation does not establish accuracy or electrical safety.

In film photography forums, the same question keeps coming back: what light do you actually need to scan a negative “correctly”? From there it turns into an argument about CRI 99, about 660 nm LEDs, about how Frontier skin tones look alive while Noritsu looks plastic — or the other way around, depending on who’s talking. What’s always bothered me about this argument is how few actual numbers are in it. So I worked through six primary research works from 2018–2026 — peer-reviewed papers, conference work, and the foundational 2018 scanner-interaction report — checked the numbers against the source text, and then sat down with the published data to calculate the things the papers mostly describe in words. ...

Kit type Home / small-tank kits Professional minilab chemistry (replenished) Manufacturer Chemistry / kit Manuals and safety data sheets Units Metric (mL / g) Imperial (fl oz / oz) Desired final volume (mL) Replenishment rate Processor type This universal calculator draws from NordicLab's shared chemistry catalog and covers the common case: a fixed-fraction fresh mix, scaled to your target volume, plus published replenishment rates for professional minilab chemistry. It does not (yet) cover push/pull interpolation or mutually-recalculating volume/mass fields. Weight mode is only offered for a component when the source actually publishes that component's density; NordicLab never assumes a default density (not even 1.00 g/mL for water-like concentrates) — enter your own measured density to compute a mass for an otherwise volume-only component; that value is used only for this calculation, is never saved, and is never treated as manufacturer data. ...

Symptom: the lift arm sometimes rises on its own during a process and stays in the raised position instead of returning to normal cycling — reported to have happened mid-run on a reversal-stage E-6 process, with the film only saved because it was caught in time.

Adjusting the pitch of the processing rack When to use this: only if you removed the drive sprocket or feed idle gear from their shafts inside a processing rack (CD/BL/FIX/STB) — not needed if you only removed/reinstalled the whole rack, and not needed if you only replaced a GUIDE, FILM part without taking a gear off its shaft.

Full test procedure: heater not heating, temperature stuck then dropping Original question (paraphrased): On a Noritsu V50, the CD tank heater doesn’t seem to be heating the solution. The temperature climbs to a certain value, gets stuck there, stops moving, and then starts dropping. Write a full manual for testing this: which circuit chains to check, which board connects to what, what resistance the heaters should have, what to do if the wrong heaters (from another model) are installed, and how critical that is. ...
