I really don't feel like I'm in competition with people who shoot price tags, or take selflies in front of Starry Night, and whatever else they do with their cameras, any more than a landscape painter would feel that he's in competition with a sign painter.
And I agree with you.
But, the reality for many, is not so: I can recall, only too clearly, many years back when I was a regular on the BJP forum. This was at about the time that mainstream pro photography - whatever the hell that was - was starting to feel the effect of the digital amateur in the realm of stock. Some of the people posting in that BJP forum were clearly not even good amateurs, but had convinced themselves that they were the next about-to-happen, despite not even having held down photographic postitions, anywhere.
These special folks believed that it was just a matter of buying a camera, a light tripod and perhaps - at a stretch - a small flash. When I pointed out that it took years of struggle, experience and contacting people to get anything much to happen, that the people able to deliver unto one the choice contracts were always well-insulated by secretarial staff etc. etc., the passing of whose barriers was no easy matter, replies to such statements never came. What did come was the usual one seen here on LuLa from time to time: nobody owes pros a living! Well, how neat: who said that anyone did? So yes, you are right, the pro is not in competition with the cellphone selfie king, with the soccer mum, or even with the shamateur, stand-in weekend weddings warrior. The pro is in competition with himself, other pros, and, worst of all, with a market where the lowering of client expectations is clearly real in the greater, more accessible areas that once were a living for the general practitioner.
I suppose that signifies the markets once part of the assignment genres, now satisfied by microstock. And yes, if much advertising output is going to be confined to an uncalibrated consumer monitor, what's the point in photographic hi-fi anymore?
But on the positive: I see no decline in the workload of those master fashion photographers I admired so much during my own time... that's one advantage of the web: you can see what your heroes are doing and for whom.
