Camera too old pixel is not high, try to synthesize high-resolution large films-e3300

The camera is too old to try to synthesize high resolution pixels is not high [PConline] large digital camera pixel technique developed in recent years is quite powerful, Canon fifty million pixels and fly pixel sensor was a detention of hundreds of millions of hope and respect. But at the same time you also know that after a single SLR purchase, say ten years is not really boast. Then we used to buy only ten million head of the SLR camera, the end will not be able to create a super resolution shocking photos? Let’s have a look! What’s the difference between stitching high resolution photos and general panoramas? Before the popularity of mobile phone panoramic photos, you may not know how a very long or high picture is generated, but only follow the camera moving in one direction, you can "shoot" out. But a fool like panoramic photograph has a fatal flaw, that is, there is only one exposure in a photograph. That is, the scene is bright and dark at the same time, and you can only take one of them in one shot. Almost all mobile phones have panoramic photography capabilities, but the single photo panorama stitching we are going to introduce today is much more than the advantage of a fool like panoramic view. Single photos can be exposed, corrected and spliced later to produce larger and clearer panoramas. And the most important thing is, the stupid panoramic photos often appear fast moving objects in the process of shooting, the success rate will be greatly reduced. This problem wouldn’t happen if the sheets were spliced. Mobile phone panoramic photos will limit the length of the actual composite photos, I think the biggest significance is that you can solve a lot of fixed focus users trouble. Going out with only one 50mm fixed focus lens means that the photo of the landscape can not be photographed. But the scenery is not often, it really only took out a mobile phone click eraser? No. Stitching up high-resolution photos comes in handy at this time. Next to the author’s experience to tell you about splicing methods and matters needing attention. Mosaic high resolution photos: one step, I believe, for most of the friends who have played stitching panoramic photos know that the Photoshop inside Photomerge, the function is very powerful and comprehensive. Of course, before you use it, you have to be skillful in taking a few pictures to make a combination of them. The author takes Canton Tower as an example. PS comes with Photomerge synthetic photos, the author uses 50mm fixed focus lens, in the ground floor of Canton Tower up and down beat, only one shot at about 1/3 of the entire tower. And smart students know that the upward shot is different from the flat shot, and the final panoramic view of Canton Tower must be different from the flat shot. There is no way to solve this problem, who let us have no wings to fly, can only be synthesized on the ground from the top down to see the simulated visual photos. The three photos must have a very obvious coincidence position, the computer can only identify stitching. Take three photos on the ground (three parts of the tower), turn on the Photoshop on the computer, and then open three pictures of RAW in Photomerge, then you can begin to synthesize. Combination.

相机太老像素不高 试试合成高分辨率大片【PConline 技巧】数码相机像素近几年发展可是相当厉害,佳能五千万像素和飞思过亿万像素传感器真是令人望而起敬。可是同时大家也知道一台单反购买了之后,说用个十年真的不是吹嘘的。那么我们以前购买的只有一千万出头的单反相机,到底能不能够创造出超分辨率的震撼照片来呢?一起来看看吧!拼接高分辨率照片跟一般全景照片的区别?  在手机全景照片普及之前,大家也许都不知道一张很长或者很高的照片到底是如何生成的,只知道跟着相机向一个方向移动就可以“拍摄”出来。但傻瓜式的全景照片有一个致命缺点,那就是在一张照片里只能有一次的曝光机会。也就是说,现场环境一边亮一边暗,你只能在一次拍摄里兼顾其中一个。几乎所有手机都有全景拍摄功能  但我们今天要介绍的单张照片全景拼接法就要比傻瓜式的全景优势大得多。单张照片可以先通过后期进行曝光修正再拼接,最终生成出更大更清晰的全景照片。并且最重要的一点是,傻瓜式的全景照片往往在拍摄过程中出现快速运动物体的话,成功率会大大下降。单张拼接的话就不会有这个问题。手机全景照片长度会限制  其实合成照片笔者认为最大的意义在于可以解决很多定焦用户的烦恼。出门只带了一枚50mm定焦镜头,意味着风景系的照片拍不到。但好风景不常有,难道真的只能掏出手机咔擦一张吗?非也。拼接合成高分辨率的照片在这个时候就派上用场了。接下来就以笔者的一次经验为大家讲述拼接方法和注意事项。拼接高分辨率照片:就一个步骤  相信对于大部分玩过拼接全景照片的朋友都知道Photoshop里面的这个Photomerge,功能非常强大而全面。当然在使用它之前,你要有技巧的拍摄数张照片以合成使用,横的竖的都可以。笔者就以拍摄广州塔为例。PS自带的Photomerge合成摄影照片  笔者使用50mm定焦镜头,在广州塔的地面处向上仰拍,一次只能拍出整个塔的三分之一左右。并且聪明的同学都知道,这样向上仰拍跟平拍的视觉不一样,最后得出的全景广州塔必然跟平拍的不一样。没有办法解决这样的问题,谁让我们没有翅膀飞起来,只能将就合成一张在地面上从上往下看的模拟视觉照片吧。  拍摄的三张照片一定要有非常明显的重合位置,电脑才能只能识别拼接。在地面仰拍三张照片(塔的三个部分)  在电脑上开启Photoshop,然后用Photomerge打开三张RAW格式的照片,就可以开始合成了。  合成的时间长短就看电脑的处理器能力了。笔者所使用的相机拍摄出来的分辨率只有4288×2428(比现在的某些手机还要低),处理时间十秒之内就能完成。  生成出来的照片你会发现照片本身就是“小蛮腰”。原因就是任何镜头拍摄出来的照片边缘都会有畸变,而畸变的一部分又要作为另外一个位置的起点,所以必然会导致整张照片有所删减。但没关系,我们只保留中间最重要的景物即可(通过剪裁工具可以把多余的部分去掉)。最终得出最长长度达9282像素的超清照片。  原图我们也能看到灰蒙蒙的天气,照片毫无生色。你可以通过所有调色手段,锐化降噪手段来为照片增加表现力。最后还可以加上简洁文字并分享到朋友圈。对了,分享到朋友圈毁有另外一番感觉——你再也不会责怪朋友圈把图片压缩得多么厉害。(点击图片可查看原图)  为什么我们每次提到需要后期的时候都提醒大家拍摄无损格式RAW呢?看下面的生成结果你就会明白一切。JPG格式能保留的细节真是屈指可数,再通过后期来修饰的话必然崩溃。  反正你只需要明白,如果真的不打算做照片后期并且家里电脑硬盘空间也不多,就拍摄JPG格式照片。要享受更多后期乐趣,你只能选择无损格式RAW。同时也再次表达笔者一直坚持的理念:不把老相机的200%功力尽然使出,你怎么好意思说又要更换相机了呢。总结:  虽然说老相机在使用体验和功能性方面确实比不上现在新出的数码相机,但即使是十年前的老相机也觉有完备的最简单的拍摄功能。同时,现在的相机像素很高也很清晰,只是方便了我们不用拼接罢了。假如真认真起来,老相机又怎么会败给新相机呢?全景拼接的玩法非常有意思,希望大家看完这篇文章可以多多享受全景拼接的拍摄体验乐趣。相关的主题文章:
