Camera & Sensors
Sensor size drives almost everything else — depth of field, low-light performance, and how a lens's focal length actually behaves. Runs in your browser — no server call, no tracking.
Before Digital: The Cinématographe
The Lumière brothers' Cinématographe (1895) was the first practical device to record, develop, and project motion film — combining functions that had previously required separate machines, and effectively launching cinema as a medium.
The Iconoscope
Vladimir Zworykin's iconoscope (1923) was the first practical video camera tube, converting an optical image into an electronic signal — the foundational technology behind broadcast television for the following half-century.
The CCD Sensor
Willard Boyle and George Smith invented the charge-coupled device (CCD) at Bell Labs in 1969 — the first practical digital image sensor, work that earned them the Nobel Prize in Physics in 2009. CCDs dominated digital imaging for decades before CMOS sensors overtook them.
Crop Factor, Explained
A smaller sensor doesn't just capture a smaller image — it captures a narrower slice of what a lens projects, which is why a 50mm lens looks noticeably more "zoomed in" on an APS-C body than on full frame. Multiply the focal length by the crop factor to get the full-frame-equivalent field of view.
