Exposing for S-Log requires understanding the characteristics of the S-Log gamma curve and using appropriate settings for different shooting scenarios. Here are some general guidelines: 1. Understanding S-Log: S-Log is a logarithmic gamma curve designed to maximize dynamic range and preserve details in both shadows and highlights. It is commonly used in professional video production to capture a wide tonal range. 2. Set the Base ISO: Start by setting the base ISO for your camera. It is typically recommended to use the native or base ISO for S-Log shooting to achieve the best image quality. 3. Use a Histogram: The histogram is a valuable tool for monitoring exposure. In S-Log, aim to distribute the tonal values across the dynamic range. Avoid overexposing highlights or underexposing shadows. 4. Expose to the Right (ETTR): S-Log benefits from a technique called "Expose to the Right." This involves slightly overexposing the image without clipping the highlights to maximize the signal-to-noise ratio. 5. Zebras and Waveform Monitors: Utilize zebras and waveform monitors to help identify areas of potential overexposure. Set zebras to around 70-75% and adjust exposure until zebras appear on the desired highlight areas. 6. LUTs and Exposure Offset: Apply a LUT (Look-Up Table) specific to your camera and S-Log profile to assist in visualizing the final image. You may need to apply an exposure offset to adjust the brightness. 7. Lighting and Contrast Control: When shooting in challenging lighting conditions, consider using artificial lighting or modifying the natural light to maintain a balanced exposure and minimize extreme contrasts. 8. Picture Profile Settings: Depending on your camera model, there may be additional settings to fine-tune your S-Log exposure. These settings can include dynamic range options, gamma curves, and color space settings. Remember, the recommended settings may vary depending on your camera model and specific shooting conditions. It's crucial to refer to your camera's user manual and test different settings to find what works best for your equipment and desired outcome.
