An iPhone camera is capable of capturing striking images (there’s even an entire photography contest dedicated to the device). But if you’re like many amateurs, your photo stream is likely filled with washed-out landscape shots and blurry photos of your pet. If you live within traveling distance of an Apple Store, you can go there this weekend to hear practical tips from an iPhone expert—at no cost.

As Condé Nast Traveler reports, Apple is hosting free iPhone photography classes on Saturday, May 20, at 495 Apple Store locations around the world. Each session will be led by a “Creative Pro” (basically the liberal arts version of a “Genius”) or a guest artist. After meeting at the store, groups will leave its sterile interior to photograph the surrounding neighborhood. Themes differ by city: In Los Angeles, groups will learn how to tell stories through photography. Participants in Hong Kong will focus on snapping portraits of people, like selfies and group photos.

In addition to photo walks, stores are also organizing sketch walks for iPad Pro and Apple Pen users. Reservations aren’t required, but if you anticipate a large crowd at your store you can make one online.

The walks are part of a larger initiative from Apple to rebrand their stores as community meeting spaces. New events, including coding classes, music editing workshops, and iPhone, iPad, and Mac tutorials, will be taking place every day around the world. Visit the Apple website to see what’s happening at your neighborhood Apple store.
