亮度可以调整到什么范围？

You can increase or decrease brightness across a wide range. Positive values lighten the image while negative values darken it. At maximum brightness all pixels approach white; at minimum they approach black.

增加亮度会使图片看起来过于苍白吗？

Large increases can clip bright pixel values to white, losing detail in highlights. For subtle corrections, use small adjustments and preview the result before downloading.

这个工具与亮度和对比度工具有什么不同？

Yes. This tool adjusts only brightness as a single control. The Brightness & Contrast tool gives you separate sliders for both properties simultaneously, which is more convenient when you need to adjust both at once.
