Using a log recording means encoding image data with a log gamma curve that compresses the highlights and shadows, which lowers contrast and desaturates colors in-camera. This creates a flat, desaturated image straight from the sensor, intentionally preserving a wide dynamic range for grading in post. Log C is the format that is designed to maximize that flat baseline for grading, giving you ample latitude to shape contrast and color later. In contrast, Rec 709 uses a standard gamma and color space, so the image tends to look more contrasty and vibrant out of the camera. CineForm is a codec that can carry different pipelines, but without a log profile it won’t inherently produce the flat look. Log A exists, but Log C is the one most associated with delivering that flat, desaturated baseline intended for grading.
