I got into this ridiculous hobby post retirement. It is a self-satisfying way to pass the time as it keeps me off the streets and outta the bars, but, if someone approached me about making a career from photography...I would be forced to slap them up-side the head. http://work.chron.com/estimated-salary-photographer-7219.html
Aside from the occasionally successful wedding and fashion photog...who is gonna buy your stuff.
Besides the local hotel that hosts local photography and the traveling art shows that caters to folks with some disposable income...photography doesn't sell.
Peruse the "decorator wall décor" websites, photography occupies a very small subset therein, so again I ask...who is gonna buy your stuff?
