With such clear instructions I thought “Meh, how hard can it be?”. I don’t think my result is anywhere near as good as Paul’s or John’s, which just proves it’s probably harder than I thought 🙂
Given that it was a brand new mirror, straight out of the cellophane, I’m disappointed by the refraction. Maybe I was too close to the mirror.
I found it pretty hard to align the flash. It would be easier with a modelling light so I could adjust the red gel and see where the red light would fall.
