Скачать или смотреть Silk Sky - Practical Effects Cloud Tank Photography

I recently picked up a Blackmagic Pocket 6K Pro camera for the purpose of filming practical effects, so I thought I'd revisit an old school special effects technique: cloud tanks.

As for the setup, I used a 20 gallon fish tank with salt water in the bottom half and then clean water in the top half. Once that's setup I then inject various types of liquids into the tank via a syringe. Combinations include watered down condensed milk or liquid latex mixed with ammonia.
These are the results of three sessions worth of experimenting, all with one spot light placed above the tank pointing down into the tank.

All shots either use a 100mm L series F/2.8 macro lens or a 24-105mm F/4 L series Canon lens. As this video was shot with only one monochromatic single source light, I'm planning on experimenting with a new set of RGB lights for more colourful results next time.

If you have any questions or ideas please feel free to let me know.
