Final answer:
If brightness is adjusted too high, it can overexpose the photo, resulting in 'blown out' bright areas without detail. High brightness does not lead to improved render quality, realistic shadows, or reduced rendering time.
Step-by-step explanation:
If the brightness is adjusted too high under the PhotoView 360 Lighting options, it can overexpose the scene. When a photo is overexposed, the bright areas of the photo can appear all white and lack detail, a phenomenon known as being 'blown out.' Overexposure can occur if the camera's shutter speed is too slow, the aperture is too large, or there is simply too much light for the auto mode to compensate. Unlike what might be assumed, increasing the brightness to excessive levels does not improve render quality, create realistic shadows, or reduce rendering time. On the contrary, it can jeopardize the photo's quality by losing fine details in brighter areas.
