# Camera Gain Augmentation

Simulate camera sensor gain (ISO) noise to make your model resilient to sensor and lighting variation.

Simulate the noise introduced when a camera boosts its sensor gain (ISO) in low light, helping your model stay robust to grainy, sensor-noisy images.

* Variance multiplier: Controls the strength of the simulated sensor noise. Higher values produce a grainier, noisier image.
