Not really an expert in economics and the world of photography, but I have made some educated observations that are common-sense to me.
The days of the common photographer getting highly paid are over in this digital age. Photographers had to be more skilled in technical in the days of film with all the processing and the expenses, which is why there were fewer artists around compared to today. Most photo-blobs and forums will have complaints about how its so hard to make money in the market today due to the mass flooding of photographers because of the availability of inexpensive equipment.
The truth is that yes its harder to make money with the old business model for photography. You have to shift and adapt to the times. You have to be more efficient in your thinking and approach.
While technology has made it easier for mediocre artists to surface it has also made it easier for great artists to surface.
Most photographers are shooting the same quality of work that was done in the days of film due to how easy digital technology has made it. In the flooded market you have to do more to stick out. The same attention to detail and work ethic is needed to be applied in the digital age as was found in the film days. If you put the same amount of work into your craft you will rise above the rest. The quality of work has to be amazing, blow people's minds!
(not saying I have learned how to do this or achieved this, its just an observation)
If you do what is stated above your work will need to be placed in the proper avenue or market. In a frictionless environment that the internet gives us, our work can be seen by millions in a matter of days. If someone likes your photo they will pass it on to those who will enjoy it as well. Word gets around and the old principles of marketing still apply in the digital age, things have just changed a little bit.
So put the effort in, do better than the guy you are competing with and find the right market for your brilliance.
Simple right?
