What is Rain-X and how can you use it to create some interesting images for macro photography?
Rain-X is a glass cleaner that repels water when applied to a glass surface. Most folks use it on their car windshields to bead the water. I use it to create fun images of water droplets that contain refracted image of a flower within.
I first tried this technique several years ago and while I like the look of some of the images I still find it to be a bit of a novelty BUT still a lot of fun to play around with on a rainy day. You never know what you’ll come up with!
First of all you will need a rectangular sheet of clear glass, two side supports to hold the glass up off of the floor approximately one foot, spray bottle filled with water, flower/flowers, small vase (you don’t want the vase to show up in your images -so the smaller the better) and camera gear.
The setup is easy; position the supports to hold the glass. I use buckets since they are light weight and inexpensive. Place the glass on top of the buckets, with the buckets on each side of the long edge of the glass. On the clear glass spray the Rain-X and allow it to dry, After the Rain-X dries use a spray bottle filled with tap water and spray water on top of the glass. The water will bead up and create several water drops. Be careful not to spray too much as the water drops will run together forming one giant water drop instead of several small drops. Place the vase approximately 6 inches underneath the center of the glass and put your flower/flowers in the vase. Next put your camera and macro lens on a tripod and set it up so that it is parallel to the glass.
Being parallel to the glass will put all of the drops on the same plane of focus allowing for greater depth of field. I like to use an aperture of f/8 for this type of set-up for macro photography. If you use a wide aperture many of the drops will not be in focus. If you stop down too much then the flower/flowers that you placed under the glass will appear much more in focus and become a distraction. The image of the flower or flowers that you placed below the glass will be refracted by each water droplet.
