If you think there's an app out there for everything in photography, you're pretty much right. There are few things that apps don't do anymore, and, when it comes to incorporating new things like artificial intelligence, the sky is truly the limit as to what smartphones and computers will be able to do to photographs in the future. One cool innovation that's received a lot of press lately is the Spectre app for Apple's iOS systems. Basically it's a long-exposure app that uses AI to simulate what would normally take a long time to capture. Coming from the same team behind the Halide app, Spectre can make "moving subjects disappear in busy areas, such as the cars on the bridge below, or you can create light painting and other effects through subject motion, just like when shooting with a DSLR that has been set to a long shutter speed" according to DPReview.
