Not sure if there is a specific course on floral photography, however, naturally I would tend to want an outdoors related course for that. Anywhere in/near nature like the botanical gardens (although simple) springs to mind. Otherwise the Chinese Gardens at Darling Harbour. Worth the entry fee to practise in serenity.
Fagan Park in Galston! It's got assortments of flowers around every corner, absolutely beautiful and just waiting to be snapped! My dad loves photography so I definitely recommend that beautiful place.
They sound like wonderful ideas. Justine, I was actually planning to visit the Chinese Gardens again soon if possible, since I am always in the city for my study and the gardens are so conveniently located! The Botanical Gardens are also a brilliant idea. I also know that I have seen some amazing parks in the Blue Mountains area, around Leura and Katoomba. Hopefully I shall be able to develop my skills further there as well. I am planning a trip there soon with my mother and so hopefully I can practise my photography there also.
Kat, I shall have to keep your recommendation about Fagan Park in mind also. It sounds lovely, hopefully I shall be able to visit there soon!
I think sometimes just walking around the streets of your own neighbourhood can yield amazing flower photography photos. Doing this I've come up with some stunning photos of giant roses, an enormous bright hibiscus, flowers just raining down from a tree, and tubs of herbs with signs saying people are welcome to take some home with them. It's amazing what you find if you just walk around a bit!
