Not sure what smartphone you have, but most of them allow you to put it in manual mode. Set the ISO to 400 or so, and manually focus. Then it will be consistant.So I have finished editing the video, a few issues, since the ISO was so low, it makes the overall image appear darker when the tv is not that dark, I had to offset this as my overall issue was bright objects were being blown out.
I calibrated the phone to Blade Runner, there is also times where the phone struggles to focus, I did this during day time so might do another run tonight when I have no ambient lighting.
Also slight slant on camera :/
EFNY takes drastic hit, as does 2049 with darker scenes.
