My involvement in the production of one of these ' Specials' was supplying the original multi layer photoshop drawing that the scheme was designed on (Plus showing the guy who designed the scheme how to use items of the photoshop software required to create the design). The bloke who designed the scheme in question wrote an article in a monthly aviation magazine that explained all the hoops that have to be jumped through to get the scheme on the aircraft. As for knowledge of camouflage schemes, having had to do aircraft profiles from the early days of the RFC through to stuff that is still in service, I've had to research the subject to find the correct scheme for an aircraft at a specific time period. In a lot of cases its resulted in a trawl of the bookshops as well as the internet. In a few cases the book explains how the camouflage scheme came about.
