My, there are a lot of 'professionals' here
So, a photographer? Well traditionally not adjective 1 - that would be lawyer, doctor, architect etc. What about adjective 2? If it's your main income then yes. Otherwise no.
The noun is straightforward - only if it's an accepted profession.
I've met (in the real world) a lot of photographers. Most of them are amateurs, some good, some not so good as photographers. Some of them shoot a few weddings. They are amateurs. I've met some professional photographers, some good, some not so good. They are all professionals because it's their main income, although some of them may not behave/act/practise in the 'professional' manner that they should - like using a dual slot camera at a wedding. But they are still professionals because they earn their main income from it.
There is a long history both in Europe and America going back to the 19th century of amateurs in all sorts of fields, including photography. And many more in science and other fields. Some of them, because they had leisure did some truly amazing things, they just lacked the structure of academia or business, but quite often they were better at what they did, or innovated more than the 'professionals'.
I'm an amateur, although I have trouble spelling it. I don't want to be paid for what I do, although an hour ago a company called me and asked me to do some work this week, and I said yes.
Are we OK now with what a professional is?
