Snellma.... Believe it or not, everyone of those flower photographs was taken with a FujiFilm A303 3.2 mega pixel camera in macro mode.... That is about one step up from a "throw away digital camera". I have won several photo contests, participate in arts shows, and have my work in a gallery of fine art. I have only been photographing flowers around my house for about a year now.... And to be honest, I don't know "F" stop from "door stop", and I am NOT an artist....
In order to expand the scope of my work, I had to upgrade to a DSLR camera with a macro lens, flash, remote shutter release, and tripod.... In addition to learning about using the camera (extremely complicated), I also have to learn how to use the photo processing programs like PhotoShop CS2 and Elements 6.0 to name a few.... The irony of all this is that my photographs are displayed in a gallery of fine art, and now I have to spend all my spare time learning how to take pictures..... I hope that this helps you... Anything else, please let me know...
