The orchid was lit from the side with a softbox and there was a silver reflector behind as he background, the reflector was placed outside the path of the light to avoid creating a big wash from the back. (Sometimes you have to work with what you have, and I did not have another background to work with.) Additional light was added to the flower in the image above by shining a small LED flashlight onto it during the exposure. A bit of light painting even whilst including flash. Always consider options in your photography, you may surprise yourself with what is available to you!

I’d love to see your own light paintings in macro work.
