Zhuhai aerial photographer "no focus", the original name Rong Nan, now living in Zhuhai, Guangdong, senior landscape photographers, national senior photographers, exhibition planners, drone registration flying hands. Compared with Rong Nan, he hopes that everyone can remember that "Zhuhai has no focus."
"No focus" high school has had the experience of flying fixed-wing aircraft model. Later, by chance, he made a whimsy and got a car recorder installed on the "Sky Surfer X8". The photos taken by the vehicle recording instrument can be Imagine that the income was all a paste, and it became a group of Impressionist works. It was called "no focus" by the filmmakers, and then simply walked the rivers and lakes with "no focus".
There is no focus contact photography for more than 30 years. The first camera is a toy camera in junior high school. There is no aperture. There is only one steel shutter. It can hold a black and white scroll of 120. This is a toy camera, which is interested in photography without focus. Next, the Seagull 4B double mirror, Nissan SLR 135, and then more and more advanced equipment, more and more subdivided themes, and finally settled in landscape photography.
Non-focus teachers often look for angles for a perfect photo. It is common for a landscape photo to climb the mountain to find the angle. Even so, he always felt that his photos were not perfect and the angle was not high enough. Once, he took a plane from Zhuhai to Beijing in order to take a picture of Zhuhai scenery at a higher angle. Later, even the ticket sellers at the airport were familiar with him. If there was no focus to buy tickets, the staff would give him a window position.
The earliest known aerial drone with no focus is the S900 of Dajiang. He accidentally saw the use of TV stations and enterprises. No focus has been played while they are using it. He said that the imaging effect of the flight is very good, but the battery life is too short, and it will return after a few minutes of flight. But this is enough to make the focusless heart, but at that time the price of the S900 was 90,000, and it was also equipped with a dedicated cloud platform. Together with the independent camera, it could not afford it at the time of economic ability, only as a "dream, A small goal." After that, no focus began to intermittently contact the aerial photography of the drone, and there was never a drone of its own. Finally, in April 2015, Dajiang Company launched a small integrated aerial drone “Dajiang Elf 3†with a price of 6,990 yuan. He felt that the performance and price were acceptable, and there was an old city renovation project. I started a drone. Since then, I have found a new direction of landscape photography, which is out of control. At the same time, he found that the panoramic photo taken with the drone was amazing. The previous panoramic photo was only seen in Google Maps, and at that time, even if the individual wanted to use the drone to make a panorama, it could not be displayed. Published platform, 2016, no focus to understand 720 cloud website, and the emergence of 720 cloud, let no focus feel that using a drone to make a panorama is worth a try.
On July 20th, 2016, the weather was very suitable for aerial photography, and there was no focus to take aerial photography in a place that was optimistic. After shooting a few sets of photos, I took a group of panoramas. When I passed the 720 cloud at night, there were more than 400,000 hits. The Nanfang Daily published an exclusive interview with the article titled "Zhuhai Panoramic Viewing Amazing Circle of Friends": "This group of images that have caused many Zhuhai citizens to resonate from the circle of friends late in the night of July 20, with the charm of 'city sky, small city scenery', in the next few days, at an astounding speed In the fermentation, this group clearly shows the beauty of the urban texture of Zhuhai's mountains and seas, the land islands, the euphemistic, the elegant and romantic. On the WeChat-based social platform, the public is proud, forward and share. The wave of praise has come one after another, which has given birth to a chain-like effect..."
No focus, how to shoot and make this panorama with the experience of the time.
Filming locations
At that time, it was aerial photography at Xianglu Bay in the Dawan District of Zhuhai. Because that area is a combination of beachside beaches, fisherman statues, opera houses and other business-style attractions in Zhuhai. At that time, there was no focus on shooting the opera house, so the choice was on the top of a 30-story building near the Opera House. After the filming was completed, he found that from the perspective of the drone, he could turn the Zhuhai. All the attractions on the business card are included, and the performance in the form of a panorama will be perfect.
Flight altitude
At that time, the flying height was 120 meters, and the building with no focus selection took off more than 100 meters, so the height of the flight should be about 200 meters.
Shooting method
No focus to tell reporters, in fact, the 720 panoramic shooting method is more complicated to introduce, but its actual operation is very simple, mainly to take a picture at 45 degrees, the last one, the next one to take a total circle, and then import software Composite output. At that time, a total of 33 pictures were taken without focus, and three layers were shot up and down, and finally one piece was stitched together.
The most important thing about shooting a 720 panoramic picture is to find the point of the cut-in. There is no focus. At that time, the photo was taken many times. The first time I took the center of the opera, shooting a whole clockwise or counterclockwise, and then adjusting the angle. Then the overlapping points were taken, and they were shot at 45 degrees, 30 degrees, and 90 degrees respectively.
There is no focus to tell reporters that now Dajiang's Yu and Xiao have a one-click panoramic function, but many people think that the synthesized photos are very fake, the main reason is that the sky is not taken. During the process of shooting 720 panoramic photos of drones, there is a part of the sky that is not photographed, and the panorama used in the one-click synthesis may be made up of several preset skyes, but the sky at different times and different locations is definitely Not the same, all are prone to the phenomenon that looks very fake after synthesis.
No focus told reporters that he would specifically scan the sky where the panoramic picture was taken at that time, using the sky at that time, the light at the time, and then synthesizing, it can be said that it is seamless.
Precautions
No focus means that if a newbie wants to use a drone to take a panoramic photo of 720, the most important thing is to remember to keep a 1/3 overlap during each rotation between the picture and the picture, that is, leave the picture and figure The coincidence point between. Because in the final computer synthesis of the panorama picture, the computer needs to find the coincidence point of the picture and the picture to be synthesized.
Without focus, many people take panoramic photos at sea. After the shooting is completed, they cannot synthesize the panorama. The main problem is the 90-degree vertical photo. Because the sea is full of sea water, the computer cannot recognize the reference point. Usually take a panoramic view of the sea, and you should find references such as nautical boats and lighthouses. It is best to use fixed lines as reference objects. This makes the computer synthesis more perfect, but if there is only blue water, the computer cannot be distinguished and synthesized. .
In addition, it is the sky shooting, because some of the drones are not captured by the sky, and the selection of materials is preferably the sky shot at the same time and place. If you don't have this material, you must choose the direction of the light. There are a lot of beginners who have such questions. Why do I shoot a panorama, the edges of the spherical image are always gray, and the blur is unclear. The main reason is that the light does not match the material you shot.
About the later stage
No focus considers the post-processing of aerial photography to be important. He believes that the problem that needs to be solved in aerial photography is the quality of the image. Even the quality of the UAV or the higher-level drone can not satisfy him. Now the largest CMOS in the largest drone is just three-quarters of the system. The video may be satisfactory, but in photography, it is the level of card machine and fool machine. The picture quality is not up to standard, so the later upgrade is very important. .
No focus means that the drone usually has a low pixel when taking photos. Although we look very clear on the screen, when we come back, we can find a lot of noise when it is zoomed in, and the color is gray. No focus When shooting, the continuous shooting mode is usually selected. At least one photo will take more than three shots. Assuming that a patch originally requires 3 photos, then at least 9 to 12 photos are taken without focus. He will first superimpose the duplicate photo stack in the PS, and the resolution of the single photo will be greatly improved after processing.
Before the panorama is synthesized, no focus will first perform synchronous PS processing on the captured picture. Because PS can open multiple images at the same time, he usually selects all imported images, and performs a synchronization process regardless of the quality of the images. The goal is to synchronize the intensity of each photo. Because it is a 720° panoramic shot, the photos taken are backlit and smooth, and a single photo is processed to ensure that each light is normal, but the light will be broken when the panorama is combined. After batch processing the images, just click Save and import the images into the specified folder for panorama synthesis. No focus means that there are a lot of panoramic image processing software. The most commonly used version is the Chinese version of PTGui. The operation is simple and clear, and the effect of stitching pictures is better. After the synthesis is completed, it is imported into the PS for sky filling.
About flight preparation
No focus means that beginners often have this experience when flying a drone: choose an attraction for aerial photography, and control the plane to fly up, that is, choose the angle, consider the composition, pay attention to the stability of the aircraft, worry Will it be a factor such as a bombing machine, and it’s hard to choose a good angle to prepare for the photo, and the plane has no electricity. After rushing to finish shooting, I felt that it was better to look down at the angle when shooting. Is it better to wait for the plane to go backwards?
The reason for this embarrassment is that the preparation work before the aerial photography did not do the job. There was no clear shooting target before the shooting. I didn’t have a deep understanding of the place I wanted to shoot. I just rushed to shoot it, but I didn’t have a detailed route. Planning, busy, and ultimately can not shoot the works that I am satisfied with.
In the interview, there is no focus: photography is a regrettable art. After the pictures taken, it seems that there will always be flaws, and many details can be improved. Inadvertently becoming a "net red", which led many commercial organizations to find him to cooperate, and they began to improve the method of panoramic shooting, and the shooting of the panorama is more and more convenient.
In the end, there is no focus. I used to shoot on the ground with a camera. Although I often have works of great color, I always feel that something is missing. Nowadays, I use the drone to shoot. Instead, I feel that I used to shoot in the two-dimensional world. Now I have a new perspective and new vision for landscape photography. I also have a group of new friends who play airplanes.
