In the UK and Ireland there are 2 criteria that I go by:

1) Accreditation by the National Union of Journalists as a photographer requires that you earn at least 50% of your total income from photography. I've been a member since 1981.

2) Again in the UK and Ireland, the term 'professional' legally applies to anyone who earns any amount of income from their work and declares it for tax purposes. In this case, the term 'part-time' can apply if the income is split with other work. When that happens, the tax relief (on workspace, equipment etc) may be proportional, in relation to the income earned and the time spent at the specific work.
