I know a very well known and respected photography teacher in my country. One day at my home we were both discussing photography, when I asked him about his views on stock photography like I always ask all professional photographers. As always he had some prejudiced views about it without full knowledge about the business. I always find them keeping away from the stock business for whatever the reasons. And after a general conversation on it, he tried to wind up the topic as it was not of his interest. But suddenly he paused and asked, “Do they accept pictures of flowers?” I was like… huh.. no!
Macro is the best way to click flowers but this way of clicking them is also saturated. What is needed more in clicking flowers is exploration in the wild to find more exotic species than clicking the roses, lilies or tulips that are easily found by a person in their backyard. The colors, texture and the shapes of the flower matter a lot because they will define the whole picture whether you click it in macro or with some other technique. Surely, clicking a flower in the conventional photographer way is not going to work if you want to sell them in stock or put it up in your exposition/exhibition. Let the world see what they normally won’t see with normal eyes. Let the see the flowers through your vision or your camera lens. Add some additional subject to them, like maybe an insect or a person, it will give more creativity and make difference to the picture.
