Let's us look at another scenario here on the various paths to earning a living from photography.
Say someone sufficiciently motivated, mature and have some savings to buy a set of studio lightings etc. and have amassed enough gears in his amateur years and sufficient knowledge of photography and Photoshop. Basically he is a self-taught photographer.
Could he start it all up on his own by finding a room somewhere as his studio and make it without going through spending several years as a photographer assistant in a studio as mentioned in a few threads here?
There may be a few photographers who have done in this way in CS.
