TiltShift Generator combines blur and other depth-of-field effects to make objects in your photos seem miniature. To get the miniature effect, you'll ideally take photos from some distance, but even close-up shots can be put through TiltShift Generator with good-looking results.
TiltShift Generator does a great job of taking you through the process of creating tilt-shift images. The app automatically adds the tilt-shift effect, but you can also go through the process yourself. You start by either taking a photo with your iPhone camera or choosing an existing image from your library. From there you can adjust the blurred effect; change color saturation, brightness, and contrast with sliders; and then adjust vignetting (corner shadowing). What results is a unique image that's very impressive, even if you have little knowledge of photography.
Overall, TiltShift Generator is an easy-to-use app that produces great-looking images with little work. If you enjoy looking at tilt-shift images and want to try making some of your own, this app is a great option.
