The image noise is the additional signal, generated by the electrical activity in the sensor. Noise is mostly visible on the uniform surfaces (like blue skies). Noise increases with sensitivity (ISO), exposure and temperature. The main problem of the noise reduction is that due to the impossibility of exact division of image data to useful signal and noise, the noise reduction leads to the loss of image details. This becomes mostly apparent in low-lit areas of the image, where details are indistinguishable in noise, and the noise reduction removes both the noise and those details. The noise reduction feature of PhotoAcute Studio, based on combining several photographs of the same scene, reduces the noise while leaving the image details. 1. Take a sequence of continuous photographs. 2. Transfer the photographs from the camera to PC. Photographs from a mobile phone can be transferred via Bluetooth or Infrared connection. 3. Launch PhotoAcute Studio. Load the photographs into PhotoAcute Studio. Click "Open" button to open the pop-up file browser or drag-and-drop the files to PhotoAcute Studio window. Loaded photographs are listed on the left panel. Marked photographs are shown tiled on the right, if the "Tile" box is checked. |

Click "Start" button to open the processing options dialog and start processing.
By combining several photographs PhotoAcute Studio automatically reduces the noise in the photographs.
The main problem of the usual noise reduction techniques is that the more noise is reduced - the more image details are lost. This becomes extremely apparent on the low light scenes (e.g. night photographs or shadowy parts of the scene).
PhotoAcute Studio provides high noise reduction without losing the image details.

| source photograph (one of a set) | photograph, processed by the noise reduction utility (one of the leaders on the market) | whole set, processed by PhotoAcute Studio with NO superresolution |
Usage: Noise reduction is performed automatically.
5. Examine the result.
PhotoAcute Studio provides you with an easy and effective tool for comparing the result to the original images. Once the processing is successfully completed, PhotoAcute Studio displays one of the original images and the resultant image side by side. When you drag one of the images (by mouse), the other one is moved correspondingly. You can drag single image without moving the other one by pressing [Ctrl] key while dragging.
6. Save the result.
Select the photograph you want to save from the photographs list. Click the "Save" button.
