Tumblr has a very nice series of animations that happens when you enter the compose mode. I thought it would be interesting to recreate this in Proto.io to show others how to achieve these kind of effect in their own protototypes.
I have made a companion tutorial video where you can see exactly how I did it. This video is available here:

Using color adjustment and filters, I've simulated the iOS spotlight animation. Learn how you can apply these filters at https://proto.io/en/new-features/adjustments-filters/
