Photokina, the photography “show of shows,” opens in Cologne, Germany on September 20. The size of this biennial event is monstrous—you have to experience it to believe it. In 2014, a total of 1,074 exhibitors from 51 countries hosted 183,297 attendees. We’re taking serious show here. In honor of Photokina, here’s a pop quiz to test your knowledge of photography. 

My friend Kasia (not her real name) bought a Click Bit bracelet last month to track her photography activity and immediately became obsessed with recording every detail of her camera life.

I’ve been taking pictures for so long that when I began, practically all cameras were made in Japan or Germany, ISO was spelled ASA and image files were paper folders where sleeves of negatives were stored.

Adobe Photoshop Elements is a budget-friendly image editing package that’s designed for casual users and amateurs. Under the hood, however, there are dozens of advanced features and hidden capabilities that are accessible via plug-ins. Wouldn’t it be cool if you could unlock, say, 130 of those features with one add-on product that costs less than fifty bucks? Then here’s good news: you can.
