Filming underwater can be achieved using various methods, including utilizing readily available devices like smartphones protected by watertight seals.
People often film underwater with their phones. A common method involves sealing the device in a ziplock bag to make it watertight. For better control and stability, they might employ a gimbal or secure the phone to a weighted box that is moved to track the subject.
Simple Methods for Underwater Filming
Leveraging existing technology is a popular approach for basic underwater videography.
- Smartphone Use: As mentioned in the reference, people do film underwater with their phones. This is perhaps the most accessible method for beginners.
- Watertight Sealing: The primary challenge is protecting the device from water. A simple, cost-effective solution is to seal their device in a ziplock bag, making it watertight. While basic, this can work for shallow depths and short durations.
- Stabilization: To improve footage quality and track movement:
- They might use a gimbal to achieve a smoother shot. Gimbals help counteract shaky movements.
- Alternatively, they could secure the phone to a weighted box that they'll move around to track their subject. This provides stability and a base for controlled movement underwater.
Equipment Considerations
While the reference focuses on simple phone-based methods, more professional underwater filming involves specialized gear.
- Waterproof Cameras: Cameras specifically designed to be submersible are available.
- Underwater Housings: For non-waterproof cameras (including many professional models), custom-built housings provide a watertight seal, allowing them to be used at significant depths.
- Lighting: Underwater environments often lack sufficient light, requiring specialized underwater lights or strobes.
- Filters: Red or magenta filters are often used to correct color balance, as water absorbs certain wavelengths of light.
| Method | Equipment | Protection | Stabilization Options | Suitability |
|---|---|---|---|---|
| Smartphone | Phone | Ziplock bag (basic) | Gimbal, Weighted box | Shallow, Beginners |
| Waterproof Cam | Dedicated Waterproof Camera | Built-in Waterproofing | Handheld, Mounts | Various Depths |
| Camera w/ Housing | Non-waterproof Camera | Specialized Underwater Housing | Mounts, Rigs | Deep Diving, Pro Use |
Filming underwater, even with basic equipment like a phone in a ziplock bag, requires careful preparation and awareness of the environment to capture clear and stable footage.
