Many people like to pursue a wider horizon, shooting the magnificent "scenery"; However, there is edge distortion in wide-angle and ultra-wide-angle lenses with large transverse field of view. Panoramic film technology, came into being.
Now the Light Stand Exporter would like to share with sth. you.
The so-called panoramic lens, is to use a longer focal length, smaller deformation of the lens to take many photos, and then use post-production software to put together a composite, which can expand the horizontal field of vision and no wide-angle distortion, killing two birds with one stone.
It sounds simple enough, but it often causes problems. This article has sorted out some key technical details and matters needing attention of panoramic film method for you, so that you can get twice the result with half the effort.
"If a worker wants to do his job well, he must first sharpen his tools." To achieve professional panoramic effects, you need to be prepared in terms of equipment -- no more, no more expensive, but all three categories.

Some subjects can not be shot without a tripod, panoramic film is one of the most typical examples.
The essence of panoramic lens is to take multiple photos and then compose one, which avoids the barrel distortion at the edge of ultra-wide Angle lens. But there's another problem: if there's not enough continuity between adjacent images, stitching can go wrong.
Especially when there is a continuous linear extension of the scene (such as horizon/sea level, road, railings, branches, etc.) in the picture, once the splicing is wrong, it will be particularly dazzling:
In order for the stitching to work, you must use a tripod to keep the position relatively stable and increase the success rate. For the first time, you'll need additional tools.
If you often take panoramic photos, you'd better prepare a panoramic cradle head.
Panorama head often has the capacity to 360 ° rotation, can put the "lock" rotation in the horizontal direction, and with a scale, to facilitate you control the amount of each rotation.
In addition to panorama, panoramic head shot other subjects are also very appropriate, do not worry about "buy a free range of very narrow equipment"; Also, it has a lot of price points, not necessarily very expensive.
The slider is an "optional" device, and it's not impossible to shoot without it, but if you want to get the best out of it, get one.
When taking panoramic photos, its main function is to reduce the Angle difference caused by rotation.
If you don't use the slider, the center of the rotation -- the center axis -- is a distance away from the lens, which will cause a certain Angle difference and affect the quality of the lens. Moreover, the longer the focal length of the lens used, the greater the Angle difference will be.
When the slider is not used, there is a certain distance between the central axis and the lens
If you use a slider, you can bring the lens closer to the center of the rotation, objectively reducing the Angle difference, and the resulting composite quality reduction.
After using the slide rail, the distance between the central axis and the lens is greatly reduced
In addition, if you don't have a built-in level on your cradle head or body, you'll need to bring your own bubble level.
