You might have just read that title and wondered what a "cloud tank" is. Check out this great video that'll show you how you can create stunning product shots using a little at-home ingenuity.
Coming to you from Max Bridge of Square Mountain, this awesome video will show you how to create a "cloud tank" for product photography. The idea is both simple and clever: you place the product in a tank of water and then inject the water with evaporated milk that you've colored using food coloring, and as the milk disperses, it envelops the product with beautiful clouds. Of course, there are a few considerations you'll need to take into account, but altogether, it's a very fun technique, especially since you get different results every time, so be prepared to use multiple images to composite together the final shot. As Bridge mentions, be sure to keep shooting for longer than you think you need to, as the milk will take a bit to completely disperse and you'll get a wide range of shots. You can experiment in several ways, changing the colors, using multiple colors at once, creating a slight current before injecting the milk, and more. Give it a try!
