How to synthesize high-resolution blockbusters

Lead: The development of digital camera pixels in recent years is still quite fierce. Canon's 50 megapixel sensor and Freescale's 1 100 megapixel sensor are really admirable. But at the same time, we all know that after buying a SLR, it is really not bragging to say that it will last for ten years. Then, the SLR camera we bought before was only10 million. Can you create a super-resolution shocking photo? Let's have a look!

How to synthesize the difference between high-resolution mosaic high-resolution photos and general panoramic photos?

Before the popularity of mobile phone panoramic photos, everyone may not know how a very long or high photo is produced, just moving in one direction with the camera. Shoot? Come out. However, stupid panoramic photos have a fatal disadvantage, that is, a photo can only be exposed once. In other words, the scene environment is bright and dark, and you can only get one of them with one shot.

Almost all mobile phones have panoramic shooting function.

But the panoramic mosaic method of single photo that we are going to introduce today is much more advantageous than the stupid panoramic mosaic method. A single photo can be corrected by post-exposure, and then spliced to finally generate a larger and clearer panoramic photo. And most importantly, if there are fast moving objects in the stupid panoramic photo shooting process, the success rate will be greatly reduced. If the sheets were spliced together, there would be no such problem.

The length of panoramic photos of mobile phones will be limited.

In fact, the author thinks that the greatest significance of composite photos is that they can solve the troubles of many fixed-focus users. I only took a 50mm fixed-focus lens when I went out, which means that the photos of the landscape department can't be taken. But good scenery is not always there. Can you really just take out your mobile phone and brush it? Not exactly. It comes in handy to combine high-resolution photos. Next, I will tell you the splicing methods and precautions according to the author's experience.

Splicing high-resolution photos: only one step.

I believe that most friends who have played mosaic panoramic photos know that this Photomerge in Photoshop is very powerful and comprehensive. Of course, before using it, you should skillfully take a few photos for comprehensive use, either horizontally or vertically. The author takes Guang Zhouta as an example.

PS's own Photomerge composite photo.

The author used a 50mm fixed-focus lens to shoot upward on the ground in Guang Zhouta, and only one third of the whole tower can be photographed at a time. And smart students all know that this upward shot is not the same as the peaceful shot, and the final panoramic view of Guang Zhouta will inevitably be different from the peaceful shot. There is no way to solve this problem. We have no wings to fly, so we can only make up a simulated visual photo from top to bottom on the ground.

The three photos taken must have obvious overlapping positions, so that the computer can only recognize the splicing.

Take three photos on the ground (three parts of the tower)

Open Photoshop on the computer, and then open three photos in RAW format with Photomerge, and you can start synthesizing.

The length of the composition depends on the processor power of the computer. The resolution of the camera used by the author is only 4288? 2428 (lower than some mobile phones now), the processing time can be completed within ten seconds.

You will find that the photo itself is? Small waist? . The reason is that the edge of any shot will be distorted, and the distorted part will serve as the starting point of another position, so it will inevitably lead to the deletion of the whole photo. But it doesn't matter, we just keep the most important scenery in the middle (the extra parts can be removed with cutting tools). Finally, the ultra-clear photo with the longest length of 9282 pixels is obtained.

We can also see the gray weather in the original picture, and the photo is colorless. You can increase the expressive force of photos by various means such as color matching, sharpening and noise reduction. Finally, you can add concise words and share them with your friends. By the way, sharing with friends has another feeling? You will never blame how many pictures your circle of friends has compressed. (Click on the picture to view the original picture)

Why do you have to remind everyone to shoot lossless format RAW every time you mention the later needs? Look at the results generated below, and you will understand everything. JPG format can retain only a handful of details, and later modification will inevitably collapse.

Anyway, you just need to understand that if you really don't plan to take a post-photo, and your home computer doesn't have much hard disk space, you can take photos in JPG format. To enjoy more post-fun, you can only choose lossless format RAW. At the same time, I would like to express my persistent idea again: if you don't use the 200% skills of the old camera, how dare you say you want to change it?

Summary:

Although the old camera is not as good as the new digital camera in experience and function, even the old camera ten years ago feels that it has the most complete and simple shooting function. At the same time, the current camera pixels are very high and clear, but it is convenient for us not to splicing. If it is really serious, how can the old camera be defeated by the new camera? Panoramic stitching is very interesting. I hope you can enjoy the shooting experience of panoramic stitching after reading this article.
