I have been photographing since about 2000. I started with a small digital camera (<1 MP from memory) and progressed to a digital SLR in 2004 and then on from there.
I have learnt a lot about still photography - macro, scenery, people, documentary, wildlife, etc. I know how to do HDR, focus stacking, flash, fixed lighting, night photography, etc. I have learnt a bit about standard video and a lot about time lapse video. I am now getting a trail camera for night, movement triggered video of wildlife and I would like to start doing tracked video for macros (tracking around a subject to show the 3D structure). All this would have cost a fortune 20 years ago, but now ....
The trail camera has cost me $200. GoPro's are about $250. High quality led lights are $50 or less. Powered tracks cost hundreds but less than $1000.
With the price of technology plummeting, I wonder how many others are doing the same sort of things - or different things.
You do have to learn to combine images from different media into a story which is far beyond what is normally done. "Heh, look at this, I took a great photo of the Opera House", isn't really enough any more - unless you are a really good marketer.
Or you need to try for something unique. Kirsty's storm photo is an example of something that catches people's attention because it is unique (and a good photo), so that is another way to go - find your own unique view of the world. I guess this is part of what I try to do with fungi and, to some extent, wildlife.
You may also have to give up the idea that your genius will suddenly provide you with heaps of money. It probably won't - but then you never know as people will pay for good stuff that is different. Anyway, making money often has more to do with business sense than with photographic or artistic skill or any other talent.
