Can be quite effective, but rather knacky. It is something different, though, and your spectators will probably enjoy it.

Great colour change and a good work out for the old fingers too. Just a shame he's out walking as he's teaching it and loses focus to stare at a car lol. But like Gabe says the effect outweighs the filming

This is a great color change, but I see it as more of a camera change. It does not require much practice, and it's very visual. My one criticism is that Gerald is walking during the tutorial, so the camera is a bit shaky, and he breathes very loud. However, the effect outweighs the filming. Great job Gerald!

Really nice and easy color change. The concept of doing the tutorial while walking is certainly innovative but sometime really disturbing. The noise surrounding and the motion of the camera doesn't really help to follow the tutorial. However, I thought it was a nice video.

This is a great change to start with. Very cool, I'm going to use it. Thanks Gerald.

This change is very nice and useful! Congratulations Gerald!

This is just an awesome color change that is fun to practice! Love the idea.

Very cool effect, very fun, and a great color change. The entire thing is great except the tutorial was a bit rushed and on the street, but other than that it was amazing.

A great addition to any routine. I definitely recommend this.

A very cool color change, I love it! Well done Gerald!

This is one of the best color changes I've seen in a long time. It may take a little practice, but when you get it, it is very fun to practice. Keep up the awesome work!
