Digital Camera Evolution: 1994-2020

What can 26 years of camera specifications tell us about the evolution of digital photography?

Project Overview

This interactive data visualization chronicles the transformation of digital photography through the lens of technical specifications. By analyzing nearly 4,000 cameras released between 1994 and 2020, it uncovers the technological trends, market shifts, and engineering breakthroughs that shaped how we capture images.

Key Insights

The Smartphone Disruption

Nokia Lumia 1080 achieving the highest sensor resolution per gram

The data reveals how smartphones disrupted traditional camera design: they achieved remarkable sensor resolutions in incredibly compact forms, challenging the assumption that better image quality required bigger hardware.

The Full-Frame Revolution
