If you want to capture a flat image for color grading, which recording format should you choose?

• A. Log C
• B. Log A
• C. Rec709
• D. Pseudo-Log

Answer: (A)

To grade color well, you want a recording format that preserves as much image information as possible, especially in the shadows and highlights. A logarithmic recording curve accomplishes this by flattening contrast and extending dynamic range, giving you a neutral, flat image rather than a high-contrast look.

Log C is the log profile designed for this camera family to maximize dynamic range while keeping noise manageable. It produces a very flat, desaturated image that provides the most latitude in post for color grading and exposure adjustments. With this kind of image, you can push contrast and color more freely without quickly losing detail.

Rec709 uses a standard display gamma with built-in contrast and saturation, which reduces grading flexibility by compressing highlights and shadows. Log A and Pseudo-Log are other log options, but they typically don’t offer the same level of latitude or color fidelity for grading on this system as Log C does.

So, for a flat image suitable for color grading, choose the logarithmic recording format that preserves the most dynamic range—Log C.
