cameras can be held in two positions: horizontal or vertical (also known as a portrait and landscape format). Photos in a vertical position can be taken later turned to 90 degrees (clockwise or counterclockwise). Rotating the photos can be automatic when the camera sensor of a sports policy.
Pulling out some photos and then turns them manually is a big problem. Usually after downloading the photos on your computer, look for them, and ifView a photo that must be activated to correct the software rotate feature. However, if one can be hundreds or thousands of photos of this process is tedious and time consuming. The good news is that this process can be automated sensor when the camera is using a policy.
An orientation sensor is an electronic device installed in the camera or it can be useful if, instead of the camera vertically and horizontally mirrored when the cameraor not (there are two vertical positions, also known as 90 degrees or 270 degrees from horizontal). We are not in the details of how this sensor (there are some options to use some physical properties such as gravity or magnetic fields) to obtain.
If a photo of the camera stores the orientation sensor, such as EXIT data in the file photo. EXIF stands for Exchangeable Image File Format, and defines a set of tags and semantics canhas existing formats such as JPG and TIFF, to provide more information on the photos. This information is the orientation of the camera.
The software can automatically follow the orientation of the photo EXIF data used as a wheel. There are several ways to use this valuable information with your performance, here are a few:
software integrated camera rotation: Some cameras have an automatic mode in which the camera rotates photoswas reading orientation immediately after the photo software with build-in rotation. In this mode, the photos are already stored in the shot in the right direction and not more, download needed.Photo rotation editing software: Some software can automatically rotate the photos as the hard disk can be downloaded from your digital camera to your computer. Before you save a picture to your hard drive, the software checks, orientation and rotates asneeded.Batch Photo Editing Software, batch operations on the photos. Usually, such software may share many common photo processing as a contrast, re-sampling, remove red eye and do more. You can also rotate photos to the EXIF orientation data.Photo based viewers: Some viewers photos EXIF orientation data is used when viewing photos. In the case of other solutions in this case against the photo file will never take place each time you view a photo changedrotate the image appears on the screen when the photo EXIF data necessary guidance. Some professionals prefer this method, as it triggers the need to rotate images to open them, but does not change the original file. Rotating a photo can degrade the quality if not properly and thus leaving the original file as is and simply rotating the image displayed is a good way to ensure no loss of quality. / Li>orientation sensors are a nice addition to the simple digitalPhotography. If you intend to take pictures, and many you may want to save time by automatically determining the orientation during the download to your computer, check if your camera has an orientation sensor, and if you're not so close that the camera is included . Today, these sensors are usually included in more expensive cameras such as orientation sensors are not a standard feature in all digital cameras have become - at least not yet
