Tech: Canon EOS 5D Mark II, 16mm-35mm EF f2.8 zoom lens @ f5.6 on manual focus. Hand-held, obs. In-camera mic. Internally the audio gain on the 5D was dialed way back to about 25% but it can't be adjusted while shooting.
Post-processing done in Adobe Premiere Pro CC 2018.
Did virtually nothing with the exposure, as it was OK enough. Dropped an unsharp mask on everything.
Dropped a DeEsser on the audio tracks (which are really one mono track written into the left and right channels) as that seemed to be effective overall. I have no clue about audio...
