The basic recipe for the bubble mixture is fairly simple and, with full disclosure, this isn't my recipe. I came across it online.
- 35mL dish soap
- 35mL corn syrup
- 2 tbsp sugar
- 200mL warm water
Stir the mixture until all of the sugar has dissolved. Then place in your freezer (or outdoors) until the solution cools and thickens. To blow the bubbles I found a thin tube with a flared end that worked remarkably well. In a pinch, any drinking straw will work.
The settings you choose will depend a great deal on the lighting and the overall look you are aiming for. I started shooting in the dark and used my headlamp to light up the scene. I usually shoot in Aperture Priority and adjust ISO to ensure I have a reasonable shutter speed to work with.
Camera: Olympus OMD E-M1
Lens: M.Zuiko 12-40mm f/2.8 PRO
Mode: Aperture Priority
ISO: 200 - 400 (Since I was using a tripod for most of the early morning shots I wasn't concerned about camera movement. However the bubble may move quite a bit if there is even the slightest breeze.)
Aperture: f/4 - f/6.3 (For most shots I was trying to maintain a limited depth of field with a nice bokeh in the background.)
This isn't a blog about composition, but here are some things to consider as you shoot;
Lighting: Experiment with different methods of lighting. In the first image (Crystal Ball) I buried my LED headlamp in the snow to create the illuminated effect. Using coloured lamps or glow sticks can also create some interesting effects. If you are using natural light choose your bubble blowing spot so as to provide the best light possible and avoid harsh shadows. The translucent nature of the bubbles is perfect for backlighting.
Distractions: Look beyond the bubble and see what else is in your frame. In a few of my shots I ended up having some branches show up in the viewfinder so I adjusted the camera position to eliminate these distractions.
Try Multiple Bubbles: If you can get your bubbles to last long enough try blowing several in proximity to each other.
Think Big: Not bigger bubbles, but a bigger scene. I am waiting for the next cold day to try this, but I would like to place dozens of frozen bubbles on the snow-covered branches of a coniferous tree.
Think Small: Try shooting some macro images of the crystals that form in the skin of your bubbles. Again, this is something I have yet to try, but will definitely attempt in a future experiment.
Unlike watching grass grow, the crystals in the bubbles form quite quickly. Keep shooting and use your images to create a time lapse video. I use the Olympus Viewer 3 software which has a built-in time-lapse feature. Or shoot video and capture the formation.
Although bitterly cold days are not ones that I usually look forward to, I do find myself hoping there are a few more so that I can experiment with this further. If you have tried this and have any thoughts to add - about the recipe, procedure, or anything else, please add a comment below.
