I don't think ti29er was affronted at a threat to his income, it was just that the OP betrayed considerable ignorance, possibly exacerbated by hubris…
The only hubris on display in this thread wasn't coming from the OP…
The words pot, kettle and black spring to mind.
I'm going to post one of my crappy amateur pics just for the sake of it, though I should really stop dicking around and hire a professional obviously.
As pointed out on a thread on TP where someone was whinging about the quality of work from a professional studio – professional is just an indicator of how someone makes their primary income, it's not a guarantee of quality.
