Just a clip of a small park near me (30 deg so I'm hiding in the shade lol ), all edited with iPad Air 2 and the Go 4 app, original files 4K but I think the app does quite a good job for basic (none pro) users like me
Dlog
+1/0/0 4K 24fps
ND16/PL (polar pro) was 1/2000, but filmed at 1/50 with filter.
Pushed up contrast and saturation on clip edit, not too bad ? Yeah not perfect, but all from iPad Air 2 on way home
