5. 操作
5.1 開關機
To power on the Rotolight RL48-B, locate the power button on the side of the unit and press it. Press again to power off.
5.2 Adjusting Light Output (Dimming)
The RL48-B's light output can be accurately dimmed using the supplied Neutral Density (ND) filters. These filters reduce the light intensity over a range of 1.5 aperture stops. Experiment with different ND filters to achieve the desired brightness.
5.3 調節色溫
The included Lee Filters allow for precise color temperature adjustments:
- Lee 205, 3200 CTO: Converts daylight (5600K) to Tungsten (3200K) for warmer tones.
- Lee 218 CTB: Converts Tungsten (3200K) to Daylight (5600K) for cooler tones.
- Lee 216 Diffusion: Softens the light output.
- 279 1/8 Minus Green: Corrects for green casts from fluorescent lighting.
Select and insert the appropriate filter based on your desired color temperature and lighting conditions.
5.4安裝選項
The RL48-B offers flexible mounting solutions:
- Shotgun Microphone Mount: The unit mounts natively over a shotgun microphone.
