Every other camera app proclaims to allow you to manually set ISO and shutter speeds. But when you try to take a picture on those other apps at ISO 2000 at 1/2 sec., the EXIF data shows they only capture the shot at 1/15 sec. This app not only successfully captures at 1/2 sec. at ISO 2000, you can push it even further to keep the shutter open for multiple seconds. You can even combine a long shutter with ridiculously low ISO values to allow controlled blurring effects (e.g., waterfalls) in bright daylight. As such, this app is unique amongst all photography apps available, and is highly recommended.
