Photokina is a juggernaut. Held every two years since 1966 (intermittently before that beginning in 1950), it has long become one of the largest, and arguably the single most important trade fair in the photo industry. Two years is a short enough interval to not miss larger trends, yet long enough to skip over fads, so the biannual trade show offers valuable snapshots that help us understand where the industry at large is moving. Photokina 2016 closed almost four weeks ago. Enough time has passed for things to sink in, so let's look back and contemplate what the most notable trends from this year's show were.
