Hence the need for a tripod or ND filter to prevent camera shake and overexposure when shooting in daylight.īut Spectre employs a computational technique that’s similar to the likes of Apple's Smart HDR to help overcome your iPhone's physical limitations, like its small sensor size and limited shutter speeds.

How does Spectre differ from traditional long exposure apps and camera techniques? Typically, both cameras and apps have created the long exposure effect by using long shutter speeds of several seconds. How Spectre works (Image credit: Spectre) Mastering the app involves little trial-and-error – in particular, with recognizing which scenes will actually benefit from 'dragging' the shutter, as long exposures are suited to particular scenes (think night-time traffic, scenes with moving water, or busy shots where you want to remove people or other moving subjects).īut fortunately, back when Spectre won Apple's App of the Year in 2019, we spoke to Sebastiaan de With (co-founder of Spectre and its sister app Halide) to get some insider tips on how best to use the long exposure app and get some good results from it on your travels. But Spectre naturally uses AI tricks to turn the effect into a point-and-shoot experience.

When using a DSLR or mirrorless camera, shooting long exposures usually involves tripods, ND (neutral density) filters to avoid over-exposure, and a whole lot of experimentation and patience. What is long exposure photography? It's a technique used by photographers who want to add some additional drama or atmosphere to a scene by opening up the shutter and allowing movement to become blurred.
