5.3 Kho xim kub
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 Kev xaiv Mounting
The RL48-B offers flexible mounting solutions:
