Negative values produce clean, professional-quality images, with the strongest effect around -2. Positive values progressively add amateur-photo characteristics such as noise, compression artifacts, and reduced image fidelity. +2 is typically a good balance, though optimal settings vary by image. Higher values increase degradation and may eventually result in excessive noise and loss of detail.
