Today I was wondering about the magic of the green screen. I was asked to submit a photo of myself, without a hat on, to the office at the new school I will be working at next month. Well, if you know me very well, you will know that there are a couple very good reasons why I wear the hat. First, as my children like to say, “what hair dad?” Secondly, I supervised the kids waiting for their buses after school for a few years when I taught middle school in Eau Claire, Wisconsin. One gorgeous fall day we had a bomb threat and the entire school evacuated to the football field. The sky was bright blue not a cloud in the sky and it was great being outside (I wish the circumstances would have been better). But, by being outside that day for just shy of three hours, I got the worst sun burn ever right on the top of my noggin. That’s right a shiny red head! And later that night I was in agony. I vowed to never, ever venture into the out of doors without a hat on my head. So, whenever I give presentations on gamification (indoors), whenever I leave a building, and whenever I have my photo taken I grab for the nearest hat.
What a lead in to today’s topic that has me wondering.
I wonder. . . . .
how is it that with some green fabric behind me, a photograph, and another image I can appear to be anywhere? I have been experimenting with, and getting better at, using iMovie and my green screen. For the photo I submitted to my school today, I simply dragged the image from my desktop into the iMovie maker and suddenly I had four seconds of video. I then had my two oldest daughters take some standard head shots of me in front of my green screen. I selected one of their photos as a jpeg image and dragged that onto the top of the previous image, clicked a button marked adjust, clicked a drop down marked green screen, and walla I had a four second video of this https://www.youtube.com/watch?v=yRhyDiKHBH8&list=UUcO54pfwAAqOaFLNJU8SL6Q
Next, I uploaded the video to YouTube then I paused the video and using Skitch I was able to take a screen shot that I saved as a jpeg file. The following image is the final result.
The only way I can explain how you take this
