Some things cannot be learned from a photograph: how much paint to carry on a brush, how fast to move an airbrush, the moment at which a wash should be wiped back out of a panel line. Timing and hand movement show up instantly on video, which is what this format is good for. This section is reserved for modelling titles issued on DVD. A disc is awkward at the bench, where a page can simply be propped open, so most modellers end up keeping both: numbered step sequences in modelling technique books, and finishing worked through issue by issue in The Weathering Magazine.
