About a month ago, Snapchat was introduced to our staff in a Lunch N' Learn. I have continued to use it in many ways. It was a great "quick tool" for annotating a process! While an iPad can be used, I utilized an iPhone.
Today, our Newscast From The Past is being recorded in front of a Green Screen.
Another example is utilizing video. The video has black bars on the sides because I used a an iPhone to video. I used Snapchat because of the quick annotation.
