After being inspired by the cool frozen flower pictures of Peter Dulis and the link he shared ( https://photographyadventures.ca/frozen-flower-photography-how-to/), I had a play and a lot of fun. I'm not totally happy and found the freezing part the hardest, so I'm planning to have another try in the next two days or so (we have a tiny freezer and after the now once-a-week-grocery-run it will be full)
Lovely. I saw Peter's frozen pictures too and thought of giving it a try. I think you have to freeze them in three stages. First put the flowers face down in a dish, only just cover the flowers to stop them from floating and freeze, then add more water and freeze again and finally fill the dish and freeze a third time.
I changed the link! Thank you!
