Ansel Adams spent countless hours in the darkroom perfecting his images. His darkroom techniques didn't make great images, they only enhanced them. Adams understood light and how his equipment captured it. When he captured an image he knew he could make it better later.
JT Smith is his workshops talks about "seeing the light." Whether natural light or fabricated, it is how we capture the light that creates an image attracting attention. Understanding light and how the equipment will capture it is the key. Not to slight composition, etc.
Photoshop is just a tool, on a computer instead of the darkroom, for making a good image better.
Making a living at photographic arts is more about marketing and running a business than the images themselves. I will probably take some hits for that statement. My point is, to be a successful, as in commercial money making photgrapher, you need to sell yourself and your images. Marketing, marketing, business sense, marketing, photography, marketing...
Unfortunately, it is likely you will need to do more of the business stuff than the art itself.
