watched a youtube video about cleaning camera sensors.
obviously the correct response was to spend a weekend building a PWA.
introducing Speck — sensor dust visualization, mapping, and EXIF reading. offline-capable, no install needed.

the trick to finding sensor dust: grayscale + invert + crank contrast to 0–2000%.
suddenly every speck you've been ignoring for months becomes painfully obvious.
built that filter into a canvas-based PWA so you never have to do it manually in Lightroom again.

Welcome Speck! - devsimsek's Blog

Speck is a PWA for visualizing camera sensor dust using Canvas API, Alpine.js, EXIF extraction, and a Rosé Pine theme. Here's how and why I built it.
