Affiliate Marketing Secrets

I have to write a 5000 word essay, and I want to lay it out by describing each setting then the characters affiliated with each environment. ~ I’m looking specifically at pathetic fallacy and foreshadowing {the general title of the essay is how Charles Dickens uses setting to influence and reflect characters feelings}

I just got a Thunderbolt, but it is lacking a feature that I wish it had. There is no way that I can find to switch from the main camera to the secondary camera while shooting a video. Are there any apps on the market that allow this? Is there some secret setting I’m missing?
