Superresolution is the method of enhancing the resolution of an image or of an optical system.
This can be done by either acquiring more graphic information (e.g. taking and merging several images of the same object) or by reconstructing the details lost due to the faultiness of the optical system (applying the knowledge of the optical system properties).
PhotoAcute Studio uses both ways to achieve the maximum image quality. It also enhances the dynamic range and the tonal range as well as the spatial resolution.
1. Take a sequence of continuous photographs. Most of modern digital cameras and some camera phones support the so-called "continuous" or "burst" mode. Several images are taken in series, usually by pressing and holding the shutter button. Please refer to your camera manual or consult the camera manufacturer/distributor for more details about using the continuous mode with your camera. If your camera does not support continuous mode, you can simply take several pictures one by one. 2. Transfer the photographs from the camera to PC. You can use cable connection to your PC or transfer the photographs directly from memory card using a Card reader. Please refer to your camera manual or consult the camera manufacturer/distributor for more information on how to transfer photographs to a 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.
PhotoAcute Studio produces combined image from a sequence of continuous photographs, thus acquiring more graphic information than it is available from one photograph. Using sophisticated proprietary algorithms it combines the individual frames to produce one large-sized and high-quality image. Such technique is usually called superresolution processing".
Unlike the digital zooming and image sharpening, resultant photographs produced by PhotoAcute Studio do really have higher spatial resolution.
Small, thin and far away objects, traceries, textures and inscriptions become recognizable.
PhotoAcute Studio superresolution algorithms are tuned for the particular camera/lens model to achieve maximum quality.

| source photograph (one of a set): camera resolution was not enough to capture the brickwork pattern | the strong sharpening does not reveal more details | superresolution applied to the whole set of photographs: the pattern is much more apparent, as if it was captured by the camera with higher resolution | sharpening applied to the result of superresolution processing, for comparison with the sharpened original |
Usage: Superresolution processing is performed when the Combined 2x output with superresolution mode is selected in the processing options dialog. Superresolution processing requires the availability of the profile for the given camera model.
It is highly recommended to use high ISO levels (e.g. 400) for superresolution processing. Camera automatically uses long exposures when ISO is low, and it leads to handshaking artifacts, that can significantly decrease the level of detail of the picture. At the same time, the noise caused by high ISO can be efficiently reduced during superresolution processing.
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.
