Actually, use any of our camera apps that extend the shutter time. My approach is to find the best app with the easiest interface to capture a scene. Many of our apps can so all of the types of photography we explore by changing the preset or mode or feature. That takes time. iPhone photography is best when you can quickly capture the moment.
Watch the iPhone Photography School video Long Exposure iPhone Photography: Advanced Techniques to see how Emil Pakarklis uses the Bulb setting on Light Trail mode to capture traffic at blue hour. He is using wired earbuds to start and stop the exposure as a remote control. Note how he is safely on a bridge and not in a traffic lane.
Think about locations that would be safe places to gather before blue hour to take light trail photos. Consider how to get height (top of parking garages) and road with curves.
- In Old Town Folsom, the parking garage is across the street from the Light Rail Station. The trains comes and go at the hour and half-hour.
- Pedestrian overpasses along Hwy 50 near Hazel or Mather Road.
- Serrano Parkway from near El Dorado Hills Blvd.
I hope to hear other suggested locations. Where are commuting bicyclists riding? Where do roads curve?
Go, play, experiment. Take a buddy along. Be safe.
