This was my first attempt using the Blackmagic app on my iPhone for a shoot.   My first issue was the shutter.  I had no ND filter and couldn't lock the shutter at 1/60.  Instead, I went auto-exposure and then locked it down when I shot.  Same with white balance.  The color temperature changed from scene to scene dramatically.  And it was a run and gun, so the color passport was not used.

I shot Apple Log Prores LT.  Perhaps I should have shot Prores or HQ. 

It turned out okay, but not much better than using the native camera app.  What am I missing?  Besides an ND filter and color correcting skills?
