Roses are arguably one of the most beautiful flowers on the face of this planet. They don't smell so bad either, which makes working around them even more pleasant. Buy the wife (or yourself) a bouquet of roses and you have days' worth of photo subject for your macro lens (and presumably a happy spouse).
For this image, I attached a Rogue FlashBender softbox to a forward-facing Canon 600EX-RT Speedlite. With this setup, I was free to shoot handheld as I worked on finding pleasing compositions – with deep-reaching soft light following me. This turned out to be my favorite image from this shoot. A nearly centered rose's petals curve outward into and subsequently out of the frame in a balanced manner.
Later, print one of your rose pictures to gain even more return on your small investment.
With tomorrow being Valentine's Day, I thought you might find this subject idea timely.
