12月20日的EchoShot Camera应用程序分析

Take a photo while overlaying the previously taken photo on the camera preview. Useful for taking photos with the same angle of view as old photos, or for puppet animations/stop motion. Photos can be displayed in three different ways: semi-transparent, outline, or pulsating (crossfade). There is also an option to display the photo immediately after taking it, which is good for continuous work.
