Systems, methods, and computer-readable media are disclosed for determining a depth or reflectance of objects. Example methods may include causing illumination of a scene within a field of view of a device at a first illuminance value, determining a distance between a first object in the scene and the device, determining a reflected illuminance value, determining a first reflectance value for the first object in the scene based at least in part on the first illuminance value, the distance, and the reflected illuminance value, and adjusting a setting of the device using the first reflectance value.
