Positivitzador WebApp
Llumàtics.com chemical photography training
Some tools make noise. Others simply solve things.
Positivitzador was born from a very specific need: understanding what you’re looking at when working with negatives. No gimmicks, no pointless filters. Open the camera, look… and see the image as a positive.
Designed for darkrooms, workshops, and photochemical processes, this small web app does one thing —and does it well—: invert the image in real time so you can read light, contrast, and composition with clarity.
No distractions. Black and white. Or with a touch of red, as it should be.

PRO Version
We are currently redesigning the entire Llumàtics.com website to expand its range of courses and workshops. During the audit and restructuring process, we identified needs that can be solved simply through small, focused web applications.
This is the first of a series of WebApps (or PWAs) we are developing at LinuxBCN for Llumàtics.
The base version allows you to easily interpret a negative image (both on paper and film), invert it in real time, rotate it, and freeze it for closer inspection.
If you find the tool useful, you can also purchase a license —with a modest one-time payment— to support this handcrafted software and unlock advanced features: saving images to your device, adding notes, using a curtain mode to compare positive and negative, adjusting exposure in steps, and fine-tuning gamma.
