• Pro tip: Hold the iPhone steady while two shots of different exposures are taken at the same time. This will prevent ghosting and blurred areas.
Slow Shutter Cam — long exposure photograph (99 cents, Cogitap): Capture light trails and blurred movement, especially like traffic lights at night or running water.
• Pro tip: Use a tripod or prop up the iPhone to keep it steady during the shot.
8 mm Vintage camera (1.99, Nexvio). This app lets you shoot retro-looking videos with your iPhone and apply effects to existing videos, Barnett said.
“It looks very real and retro and gritty,” he said. “It's obviously not for everything.”
• Pro tip: In this app, you can choose to record audio or mute the sound for making a silent movie or add a projector sound, Barnett said.
And Barnett's general iPhone tips are basic ones for beginners: 1) Get closer to your subject instead of zooming in, which reduces the quality and size of your images. 2) Think about lighting — find the most interesting lighting outdoors at sunrise and sunset — and your photos will improve. 3) Pick your best photos on the iPhone and print them: “Most people have years of digital images and very, very few actual printed copies,” he said.
