Funny. But I am not a professional photographer, and some people approach me for photos. And I show them the ones I have done, give them a price, and they say "ok". They will judge for themselves whether the pictures are of suitable quality for them.
In the UK we have a well known franchise selling family portrait sessions. They even offer a free print. If you want a couple more, they need you to take out a bank loan. And you don't know the prices until you choose your package, have seen all the lovely photos, the lovely frames, etc. Then it's a little harder to say no.
All my customers so far have known about companies like this, are aware of the excellent quality, but just don't have £1000s for a handful of prints. It's ok bemoaning the fact that "amateur" photographers are stealing the "professional's" business, but people just can't afford the prices anymore.
That said, I would NEVER put myself out to do weddings, for example, until I had A LOT more experience under my belt. Once in a lifetime events? No way. Photo shoots for friends and friends of friends, where I can shoot again if things don't go quite right, where the customer is well aware of what they are paying for? No problem.
Declaring it on taxes? You mean like people do when they sell stuff on
eBay? (not). Because that's the sort of money we are talking, here. A few quid doing a hobby we enjoy. If we get good at the hobby, and capable of turning it into a business, then sure, register everything you need to, pay all the taxes etc. that you have to, quit the day job, and go for it.
Just my 2 penn'orth.
