Why Spf?

Why Spf?

While working at Facebook we had a little tool called Preso Saver, created by my former mentor Dirk Stoop.

When I left Facebook I found myself in meetings and presentations where the screens being presented on simply weren't calibrated or capable of showing off the fine details of my work.

Light grays or hairlines in designs were too washed-out and therefore invisible on the screen. Highlights of elements—such as composed glare or highlight states for interactive elements—were practically invisible.

To help solve my problem, I re-created the Preso Saver tool from Facebook (with Dirk’s blessing). The title “Spf” comes from "Screen polarization function," a semi-trolling title that stems from the original concept for this tool as being a "Polarizer" of sorts.

Spf gives you four preset shades of darkness and a test mode for ensuring the app is working properly when presenting or projecting.

 The tool is lightweight and remarkably simple, so much so that it only made sense to open source so others can use it and customize to better meet their needs. You can find the full source code and resource files on  GitHub .
