Yes, I’m misunderstanding the part about not seeing the door. So this would be the reverse shot of her staring at the door as the light hits her face. So first off, I’d simply start with some bloom/overexpose looks along with a draw mask to feather in just the area you want to bloom. So, just dissolving to a more overexposed shot with perhaps just an area of the shot overexposed. Yes, like could have been done on set. But alas, an hour of post is a lot cheaper than an hour of shoot day. Especially if it makes your shoot day run long!
