The only photography I know of,( I am retired from this field) where money can be made is wedding & portrait. BUT you need to know your market and clientele very well.
This can vary from country to country, continent to continent. As in all businesses you have to give what the customer wants. Sometimes they don't know what they want, so you guide them along.
For example wedding photography is 79% logistics, 20% stroking egos, and 1% photographic knowledge. Customers buying wedding photography aren't buying an album or frames print, they are buying captured emotions and memories.
Do it to the customer's satisfaction and you will be rewarded financially.
Do it and exceed the customer's expectations and you will be handsomely rewarded.
You will hear a lot of negativity from some photographers about covering weddings. In my opinion, they weren't cut out for it so they bitch about it instead. Ii doesn't suit everyone and is not as easy as it seems.
The only other photographic field I know a little about is photojournalism/newspaper photography. In my opinion, there is little or no financial reward here. The camera phone is ubiquitous and so is there for every news story, be it print media, online or TV.
If I wanted to make a living from photography now, I'd to diversify into videography.
How very true, this is where most of the future lies, IMO.
