In digital imaging technology to appear before it gets panoramas channels have two: use dedicated panoramic camera rotating camera or professional darkroom ' hand stitching, whatever the method, are the ordinary photography enthusiasts very difficult to achieve.
APS camera's vaunted "panoramic" just use super wide angle lens with large viewing angle, strictly speaking, known as "cover picture" more appropriate. Digital cameras and digital imaging technology popularization bring panoramic photography becomes easier, as long as you have a digital camera and you can run the image processing software, anyone can try making perspective amazing panoramic photos.Shooting essentials for stitching panoramic photos have certain requirements, such as the exposure value similar, tonal sequence, similar, slightly overlapping each other, and so on, there are some considerations when shooting.
1. focal length of select some people think that when shooting panoramas as much as possible to make the view, so you should use the shortest focal length (wide angle lens or lens for wide angle end) so need stitching photos fewer sites. In fact, this is a misunderstanding, a shooting province conjunct is in trouble. Because of the wide angle lens perspective strongly, especially in the screen's edge, prone to distortion, stitching is very difficult to achieve seamless. Therefore, you should use when shooting deformation small during coke or telephoto shooting and filming the Midway is not appropriate to change the focal length.2, exposure parameters now number more than digital cameras have dedicated panoramic mode, in this mode, the camera automatically according to the requirements of the panoramic photo set exposure parameters for no panorama function of camera to note the following: a, metering using average metering, exposure time using the manual exposure or AE lock lock exposure parameters, the same set of panoramic photographs of the capture process cannot change the speed, Aperture, ISO, resolution and other settings; b, use fixed white balance, auto white balance can cause different photos of tone.
3 filming, photographing method in accordance with certain order (from left to right or from top to bottom, etc.), it is best to use tripod smooth rotation, rotate the camera when shooting around the vertical axis, or a point-by-point shot translated when the camera height, angle, generally do not use Flash, the Flash will kill nearly off far darker.
The adjacent picture to have a certain overlap between, Canon, Casio, digital camera in the brand of a panorama mode LCD displays have auxiliary prompt. Avoid dramatic changes in lighting conditions (such as cloud chail), so that the picture much difference between exposure. Shooting, we need to pay attention to avoid the occurrence of convergence of moving objects (such as vehicles and pedestrians). Although there are obvious signs of selected location as a bridging point to some automatic software recognition, mosaic, it is recommended that you select no clear marking, easy to blend the site as a combination, such as water and mountains, this add-on up is not easy to see the seams.
