Why did you come here asking opinions from strangers in the first place on the Internet? Does anyone here on this site pull in six-figure USD income from stock photography alone as Anderson, a well-known American commercial shooter, has done year after year? You stated you would exchange your landscape images for money in the market, didn't you? But you don't even know what sells. Anderson does tons of landscape stock. Who is in any better position to guide you? Your response shows an extremely closed mind. I aint wasting my energy any further here.
Dear Mr. Gulag (quite a puzzling choice of handle, btw),
You must have mistaken the OP with Justin. But more importantly, who the hell is "Andy Anderson"? And why should I, or anyone else, use Google to figure out what you meant? Had you stated outright what you said above about him, that would make anyone's life easier.
However, to give you the benefit of the doubt, I did bing the name (yes, there are other search engines out there, mine is by default set to Bing). Guess what? No entry on the first page of results seemed to have anything to do with photography. Only when I typed "Andy Anderson Photography" did his stock page appear. And guess what? Nothing on that page (the same one you later linked to) indicates how "well known" he is, nor how much he is making from stock. I have decades of experience in photography, the last one here in the States, and I have never heard of him.
So, in conclusion, Sir, a little bit more humility and helpful behavior, and little bit less patronizing and, frankly, jirk-ish one would go a long way in our forums.
