FaceApp unfortunately only has an ‘Old’ filter, no middle-aged filter, so my crude ageing technique can only do old old. I can approximate a sort-of middle-aged look by blending the old face on top of the young face at a reduced opacity, however.. It doesn’t really resemble Hayden’s actual ageing, though.
Morphing Hayden with Shaw is beyond my capabilities. FaceApp does have a ‘morphing’ feature but it’s fairly terrible and the result winds up resembling neither, nor having the correct facial expression. Perhaps with real dedication I could scrape together enough footage of Shaw to try to do some kind of DeepFake, but given I can only find about six different colour photos of him on Google Images, I doubt I’d have much luck (and besides, I still haven’t finished training my Fake Wedge DeepFake model…).
