Adjustment Layers Review - Hue/Saturation, Levels, Curves

Today we will review how to use Photoshop Adjustment Layers.

Creating adjustment layers

Do one of the following:
For Hue-Saturation (Converts to Black and White)

1. Click the New Adjustment Layer button  at the bottom of the Layers panel, and choose Hue/Saturation

2. Move the Saturation slider all the way to the left

3. Click ok

Here is a video showing how to do it.

For Levels (Adjusts Contrast in your picture)

1. Click the New Adjustment Layer button  at the bottom of the Layers panel, and choose Levels

2. Move the Shadows, Midtones, and Highlights Sliders to adjust the range of contrast in your image

3. Click ok

Here is a video showing how to do it.

This link will take you to a description of using Levels in Photoshop. The photo in the example is in color but it works the same in black and white.

Curves

Previously we learned how to adjust and improve the overall tonal contrast of an image with Levels using the Levels adjustment layer.

The levels tool is good for adjusting the shadows and highlights of a picture, but it is limited in its ability to adjust the mid-tones in a picture. There is only one slider for the gray tones in the levels tool.

When we use Curves we have the ability to adjust many different tones of gray in our image.

Please watch the video below to learn how to locate and use the Curves adjustment layer.
