Trying to find an AE Project Opener

Hi, I saw an opener a few weeks ago but can’t seem to track it down again. It had fly throughs and pull backs of landscape photographs but there was no slicing/panels of images, the transitions looked more like luma mattes of the images themselves so as the camera pushed forward the image would dissolve into another based on their luma values. It was unique and not something I’ve seen before on here. Any ideas?
