Hello
Little-em . I don’t have any photography diploma, and to be honest I don’t think you will need one to become a professional photographer. Even a professional photographer is not professional because this takes years and years or learning and experience, which you will never find on any course you will find cheap or expensive. Money won’t make you more skilled or give you more knowledge.
My opinion is, instead of throwing away money for a photography course, better invest on some equipment do a lot of practice, all information you can find on YouTube or Google these days. You even can ask help here, we will be happy to help you with anything we can.
I do weddings and portraits sometimes, but not for money purpose, but because of hobby, there are to many photographers on the
market unfortunately.
You have great pictures
Little-em , so don’t stop learning and practicing, that’s the way to succeed and learn new Skills. If you found a free photography course, then go for it, but if it’s an expensive, I would say to think about it. Sadly , these days, those courses are more then business.
Jack you have always quite different points of view as me
