What's the difference between contrast and brightness?

Brightness adjusts the overall light/dark level of images, while contrast adjusts the difference between light and dark areas. Increasing contrast makes images more vivid, decreasing makes them softer.

What happens when saturation is 0?

At 0 saturation, images become black and white (grayscale). Lowering saturation creates vintage or artistic effects, while increasing saturation makes colors more vibrant.

Is batch color adjustment safe?

Completely safe. All color adjustment parameters are uniformly applied to all images. It's recommended to fine-tune parameters on one image first before batch processing.
