A noisy photo is usually created using a cheaper camera, but you can also find it when taking photos with a more expensive camera, but in low light and with a high ISO sensitivity set. Noise is also created by the more densely arranged pixels on the matrix, which causes it to receive less light. It is worth noting that the noise arises already at ISO 200 settings. appropriate setting of the camera parameters just before taking the photo, but this method does not always allow for 100% denoise. The easiest way is to denoise the photo at the post-processing stage , using computer programs. There are many photo de-noise programs on the market. The most popular one is Neat Image.
It offers a multitude of setting options, allowing you to choose the amount of noise reduction without losing too much detail of the photo. A big advantage is the option to download the profile settings of several hundred cameras, which will image manipulation service allow for easier noise reduction in photos. We will meet the program in a version intended for home (paid) and as plug-ins for such popular graphic programs as Photoshop or Lightroom. Another denoising program worth recommending is Noiseware from the Imagenomic company. Here we can find three varieties, including the free one called Community and the paid one called Professional. Noiseware is not only a Photoshop plug-in, but also an independent application that allows you to denoise photos without losing their quality, without the blur effect.
The free version does not include the option of serial image processing or the ability to save information about the file as an EXIF file. The Noise Ninja program can also be recommended, but working with it may be somewhat troublesome due to the non-intuitive menu. Here you can also find a standalone program and a plug-in for Adobe Photoshop. Noise Ninja is paid for both professional and home versions. Dfine is another program, but only available as a plug-in for Adobe or Apple Aperture. A multitude of settings allows for effective noise reduction. The program is available only in the paid version, and its price may scare the average bread eater. From the more advanced programs and offering a lot of possibilities, we can recommend Helicon Filter , for the license of which we will pay pennies.
