While it may be hard to believe, snapping photographs and sharing them wirelessly using a phone first happened only in 1997, and wasn't popularized until around 2004. By 2010, almost all phones contained a digital camera and many mid-range to high-end devices also sported audio and video camcorder capabilities. Most iPhone and Android models now have these capabilities, and they have opened new pathways for entrepreneurial developers.
Titanium contains APIs that let you access all of the phone interfaces required to take photos or video with the built-in camera, record audio, and scroll through the device's saved image and video galleries.
Throughout this chapter we will introduce all of these concepts and use them to put together a basic ''Holiday Memories'' app which will allow our users to capture photographs, videos, and audio from their device, save those files to the local file storage, and read them back again.
