Noise Ninja is a powerful, proprietary noise removal tool and Photoshop plugin that try to remove noise from pictures taken with a digital camera. It applies custom settings for each digital camera to improve the effect of the noise reduction filters used. If you're looking for a way to remove excessive noise in your pictures without wasting time and effort trying out different noise removal methods, you should give this tool a try. I have found it to be very effective at removing all forms of noise from my pictures, even the random noise that can sometimes be generated by photo editing. It also removes red eye, smears, and other visual disturbances.
To use Noise Ninja, you will need to download and install the program, then open Noise Ninja up in Photoshop and click the "oggles" icon in the upper right-hand corner. Click the Browse button and choose the picture that you want to remove the noise from. If you have multiple images to remove the noise from, choose the one with the highest level of noise (it may be the oldest image). Click the "new" button at the bottom of the screen to create a new profile. You will be given several options: adjust volume, apply mask, adjust background, and apply blend.
You will need to click on each profile name to customize it, and when finished make sure you click OK. Finally, save all your changes and you are ready to apply the noise reduction filter plug-in to your picture code. It will replace your previous noise reduction filter with the new one, so please be aware that you need to restart your Photoshop in order for the newly selected profile to take effect. That's all there is to Noise Ninja, a very easy and quick method of removing digital noise from your images. I hope you enjoyed this little tutorial, see you around the web.
