There’s me, doing a little happy dance – having re-tested the colour swap under studio lighting conditions, it was a complete success!
The pics below show how the red and blue will swap convincingly, and I am more than happy with that.
Feeling a lot more positive about the whole thing now (less than 2 weeks away). Just got some final checks to do, like make sure I’ve got all the plug adapters attached to the lights, make sure the industrial fan works (since it arrived in what looked like a returned goods box…) etc. But I’m definitely on course.
