Introduction

This article touch on simple method of using noise ninja to minimise noise in a image.

Technique

This image is resize to web size posting and no noise reduction is applied.

Click on Profile Image to let noise ninja decide on which area of the image to denoise. After Noise ninja profile an image it show square box in the image where noise is detected. Sometime it detect noise on the subject which in this case is the owl. However it is not desirable to denoise the subject which will result in loss of detail. Press Control/Command and use mouse to click on the yellow square box to remove it so noise ninja would not denoise that portion.

Noise ninja allow the option to sharpen image after it denoise. I usually set the USM Amount: 0 and USM Radius: 0.4because i prefer to use other method of shapening provide by photoshop.

End result is a cleaner image and hopefully the subject remain as sharp as original. After denoise you could apply exposeure level, saturation control and image shapening depend on your preference.
