Noise can reduce the quality of the image, especially when you print it. With Photoshop, you may be able to reduce the noise. Here is how.

1. Open an image and zoom in until the noise becomes more apparent.

2. Open Noise filter by going to Filter>Noise>Reduce Noise.

3. There are two options, Basic and Advanced. In The Basic, you have these options:

Strength: this option reduces the appearance of noise. However, it also makes the softer of image. You need to balance it.

Preserve Details: use it with Strength to preserve the details.

Reduce Color Noise: This is used to reduce color noise.

Sharpen Details: this is the method to prevent softening the image.

Blur a background can draw attention to a focal point.
As always, the best way to do this is in-camera with a wide maximum aperture , F2.8 or low number. If you didn’t have the right lens with wide open aperture, Photoshop can help. In this example, we will use Gaussian Blur to blur the background.

Making selections of scattered hair in Photoshop is not easy. with a uniform background are perfect to start with. Here is how.

Decontaminate Color helps you to reduce the edge of the leftover colored pixels around the edges of a selection.

Output To drop-down menus has these options:

• Selection: When you press OK after refining the edge, then your output will be just a selection. It leaves you with marching ants.
• New Layer: Creates a new layer which contains only the selection. It deletes the background.
• New Layer with Layer Mask: Creates a new layer with a layer mask.
• Layer Mask: Add a layer mask to the selection. One of the most used output by me.
• New Document: Create a new document/file which contains only the selected pixels.
• New Document with Layer Mask: Creates a new document with a layer mask which only contains the selected image.

Curves is a popular tool to adjust contrast in Photoshop. When you open Curves, the graph will default to a straight diagonal line indicating 0 (black) to 255 (white). The horizontal axis of the graph represents the input values, while the vertical axis represents the output or adjusted values. Note: to open Cures, click on Create new file or adjustment layer.

Select Curves.

Now, you should have

Curves control contrast by adjust the curve. For example, to reducing contrast, select and drag the darkest point upwards while select the lightest point along the graph and drag it downwards as shown below.

To increase the contract, you may select three points and make an ‘S’ curve as shown below.
