Actually I disagree about "skill level"
The OP, who is probably long gone, seems to have a basic grasp of the rough technical details. It's not the
traditional approach, but it would certainly be an
efficient approach to select a niche, let's say baby portraits, and then:
- Acquire the right set of equipment
- Devote some serious effort to learning how to do that one thing
- Devote some more serious effort to practicing it
Many niches can be learned, I submit, in a handful of hours of serious work. You learn a handful of idioms, the common errors, and how to evaluate the result to see if it is good enough. If you're starting out with the right gear already in hand, you cut out a huge area of wasted hours. If you start with a good narrow niche, you can focus in on what's important.
Can you learn to shoot "weddings" in a couple hours? Nope. "sports?" Nope. "Corporate headshots" -- yes, easily. "Baby portraits" -- yeah, pretty much. How much training does LifeTouch give their operators? And how much of that is operational stuff having to do with specifics of the business model? I'm gonna guess "not much" and "quite a bit" respectively. And they can crap out excellent examples of a very very particular thing all day long.
This sort of approach is offensive to some people, who have spent years perfecting their craft or whatever. Those people feel that making statements like this is equivalent to saying that they wasted those years. It's not, but the distinction is a bit subtle. That's a shame, but I'm not going to parse out the distinctions for you.
