Last scene

The last scene in my story is grandma witness the plane taking off. And I will gradually zoom in to her eyes and try to put her grandson in it. Firstly set the opacity as zero and then change it to around 90. The problem I found in this scene is that I need to change the original size of my picture to a larger size. Because I need to put Jack in grandma’s eye which I should change the scale to around 600%.
