How would I make a long, slow transition, blending the lighter parts of a shot in first?
I've got two shots that I need to slowly blend together over the course of a few seconds. Currently, I'm envisioning a transition where the lighter parts of the second shot are slowly blended in while the first shot slowly dims to reveal the darker parts.
Here's the two different shots:


I've also got After Effects, if need be. Any suggestions are appreciated.
