Red Tulip on White
When shooting for the web or for print, it is hard to beat the versatility of a white background. And a white background is not hard to create. A sheet of paper or any other white-colored material can be used. Simply align the subject with that background and hit the white background with enough light to make it white or near-white in your final exposure. If not pure white, make it so in Photoshop.
Lighting for the tulip itself is from a softbox. I love softboxes for macro photography.
