Usage Features
The KY-D29 offers a comprehensive set of features to enhance usability and control during shooting:
- Full Auto Shooting (FAS): This function integrates auto iris, auto level control (ALC), and full-time auto white balance (FAW) to automatically adjust video signal levels and white balance, simplifying operation in varying conditions.
- LOLUX Mode: For extremely low light conditions, the LOLUX mode boosts gain by 33 dB, with a SUPER LOLUX option providing 39 dB for even darker environments.
- Digital Noise Reduction (DNR): Improves the S/N ratio, with ON, AUTO, and OFF settings to balance noise reduction with potential residual images in moving subjects.
- Shutter Speed Control: Allows adjustment of shutter speed for various effects, including reducing blur in fast-moving scenes or achieving slow-motion/freeze-frame effects. A V.SCAN mode helps match the scan rate of computer monitors.
- White Balance Adjustment: Provides AUTO 1, AUTO 2, and PRESET modes for precise white balance, with FAW for continuous automatic adjustment.
- Iris Control: Manual, auto, and temporary auto iris adjustments are available, with an AUTO IRIS LEVEL switch for fine-tuning based on lighting conditions (back light, normal, spotlight).
- Black Stretch/Black Compression: Controls black gain to improve reproducibility of black color (stretch) or reduce black gain (compress).
- Zebra Pattern Display: Displays oblique stripes on the viewfinder screen for sections with signal levels of 70-80% (or over 100% in SUPER LOLUX mode), serving as a reference for manual iris adjustment.
