Final answer:
The colour temperature of the white balance preset on DVC Pro cameras in the '1' position is typically around 5600K, designed for daylight conditions, but may vary by camera model.
Step-by-step explanation:
The colour temperature value of the white balance preset on DVC Pro cameras with the filter wheel in the "1" position typically corresponds to daylight settings, which is generally around 5600K (Kelvin). This setting is used to match the camera's colour balance to that of natural daylight. However, the specific value can vary between models and manufacturers. It's always best to refer to your camera's manual or specifications for the exact value. It's also worth noting that if you're shooting in a different type of lighting (such as tungsten lighting), you might need to use a different preset or manually adjust the white balance to match the lighting conditions to ensure accurate colour reproduction in your footage.
