Over- and underexposure (Part 2)

Today, I learnt another method to change the brightness of the picture, which is commonly used by the most Photoshop professionals. It provides more control of the tonal level with sliders to adjust the black, gray (in other term is gamma), and white.

Now, let’s try it together. Open a photo, and then click on Image>Adjustment>Level (Ctrl+L for level). You can see a big palette box. By drag white or black sliders, you can adjust the brightness of the photo. The gray slider in between white and black can help to adjust the gamma point. Using this slider can make fine adjustment to the brightness without dramatically affecting the extreme bright or dark area. Then the light of the picture will be more gentle and fine. Try yourself.

However, we may feel difficulties on adjust certain photos. Did you notice the AUTO button in the palette? Just one press, the Photoshop will let it done!
