![]() Of course if there are beautiful snowflakes around, forget the bubbles… grab a copy of Sky Crystals and get shooting! :) www.skycrystals. It’s a fun project when the snowflakes aren’t falling! I think greater success will be had with smaller bubbles, so I’ll be working on that next. ![]() Earlier in the day my experiments were thwarted by a light breeze, but that was quickly solved with various cardboard boxes arranged as a shield.įor a first attempt, I’m pretty happy with the results. ![]() Smaller bubbles tended to survive longer. The corn syrup acts as a thickening agent that makes the bubbles more stable on impact with the snow, but most of them were still breaking on contact. By the time I took a test shot with a flash, the chance to photograph the bubble will likely be over.Ĭreating these bubbles is pretty easy, and I found a recipe for stronger bubbles online: This bubble is lit using a high-powered LED flashlight which allows me to visualize the proper angle faster than using a regular flash. Shallow focus is an element you need to work around. I could push it slightly further than F/10 which is what I used here, but it wouldn’t make a huge difference at this scale. This means that focus stacking is impossible, and at the scale I was shooting the depth of field is just barely big enough. Even at the fastest rate of speed my camera can fire, the crystals show noticeable signs of growth and/or movement. Thankfully, my work with snowflakes has developed the necessary skills to most fast and work handheld, which were put to use in this image.įrost bubbles have another challenge, in that they are very dynamic subjects. This leaves very little time to get the camera and light in the proper position before the entire bubble freezes into a shell of frost. This is a difficult subject to photograph, partly due to the difficulty in getting a bubble to not burst on impact with the snow, and partly because it starts to freeze almost immediately. This been on my winter to-do list since last year, but I’ve always been so busy with other projects to make an attempt… here’s my first attempt at the subject! Certain bubble solutions contain too much glycerin to freeze. Note: Freezing bubbles either with dry ice or outside is a precise process. Carefully help students measure frozen bubbles. A fun deviation from snowflakes (there will still be one posted today, don’t worry!), I decided to try my hand a fun experiment: photographing soap bubbles as they freeze. (See dry ice frozen bubbles article in Resources section.) If temperatures are appropriate, allow students to dress warmly and take their experiments outside.
