Many photographers with a passion for flower photos had to start somewhere. To them it was a hobby and they did it in their spare time. They just couldn't plunk down $1,500 or more for a camera and lenses.
I have always loved taking pictures of just about anything. I was the person in the family no one liked to see because I was always snapping pictures.
Eventually I discovered how beautiful and rewarding flower photography can be. I was a single mother with a young child. I couldn't afford the expensive cameras everyone recommended.
Like many amateurs, I had to start somewhere. I started with a little $50 digital Kodak camera and have eventually bought better as I could afford it.
Cheap doesn't mean bad. Most of my early flower pictures are great shots. I took almost every picture in my Nature Walk Through the Ozarks article with an HP Photosmart camera with 3X zoom that cost about $75 at the time.
There are great inexpensive digital cameras for whatever your hobby allowance is.
