At the top right of the camera screen, there’s a button for toggling between the rear and front-facing camera, and at the top left there’s a control for the flash.Snapchat’s camera filters are the app’s secret weapon.For instance, the puking rainbow lens is a favorite among Snapchat users.Just apply it to your face, then open your mouth and watch a carnival of color pour out.(Custom-made geo-filters for festivities like weddings are all the rage these days.) Alternatively, before you take a photo, press and hold on a person’s face and Snapchat’s lens options will pop up.
Take an image, then swipe left or right while on the camera screen and you’ll see a filter slide over across it.(You can also swipe left one more time for the “Discover” screen, which displays stories by media entities like ESPN, CNN, and People, also a Time Inc.publication.) Sure, there are also buttons you can press to reach these screens (the bottom-left square for your chats, the top-center ghost for your account, and the bottom-right hamburger menu for your stories), but kids these days swipe their Snapchat like it’s Tinder—another app you’re probably too old to be using.From dogs wearing glasses to carnival mirror-type contortions, there’s always something new to see.And through some slick promotions, the app frequently cycles in new lenses to play with based on popular movies and shows.
