In this flower photo of a purple Iris I used a black cardboard as the backdrop. I like dark backgrounds because it really makes the colors of a flower pop. I usually choose a large enough black cardboard from Staples that I position behind the floral photographic object using the backrest of a chair for support. As a base I use the chair itself that I place in front of a window. The set up of my Close Up Photography studio next to our dining room window provides exceptional and beautiful lighting conditions in the morning. White cardboards are used to enhance the light and direct the light towards the floral when it is facing away from the window. I always use a couple of hardcover books to stabilize and minimize any unwanted shaking or movement of the flower. Additionally the books make it easy to adjust the height of the flower when a different perspective or angle is more desirable. I often adjust the white boards to explore the impact on the lighting and better control the light on the flower. Adjusting the light with the white boards is a great learning experience for us photographers and often leads to more inspirational and beautiful fine art photography artwork. In the final macro photograph of the purple iris I positioned the flower in the best possible way so that there were no other distracting branches or flowers in the composition. The light provided a beautiful illumination of the iris that keeps the viewer captivated. The aperture of the Canon EF 100mm f/2.8 Macro IS USM lens was set to f/25 providing maximum Depth of Field and an exposure time of 4 seconds. An ISO100 setting minimized noise. In the post processing steps I removed dust, minimally adjusted brightness, contrast and color saturation before sharpening the final image of this Iris over Black.
