iPhone apps vs Expensive stuff

Playing with iPhone apps tonight down at the Lake while listening to the funky music of the Rhythm Bandits. Never heard of them, but they were good. Especially their blues music.

I just spent $150 for a special ND filter for my Nikon camera that will allow me to take long exposure shots. I shot the same long exposure (60 seconds) tonight with my cheap iPhone app (Slowshutter). Results are great. No filter. The app calculates exposure for that 60 second shot. How??!! Makes me wonder where camera technology is going.

First image is an HDR using the HDR Pro app. The second is the long exposure using Slowshutter. The third is playing around stitching three HDR images together. All iPhone.
