This happens in the programming field as well. For example, I worked for a game company that has a team of over 20 system engineers working on graphics engines. Low and behold one of our content engineers makes a product on his own time (one guy) that out renders and out shines the system that these 20 guys use and releases a game in 8 weeks. The game has been used 3 or 4 times cause it simply blows away the competition and our clients love it. He's still blasted by the engineers as "not a real programmer" cause he doesn't use templayes, c++ advanced features or other such things. Gee I wonder if carpenters are amatuers cause they use precut lumber from the mill and ready made nails or are muscians amatuers cause they don't make their musical instruments themselves.
