Drone space photography, the perfect combination of technology and photography
As a scientific and technological equipment that has been widely used in film and television production, aerial photography of tourist attractions, environmental monitoring and other fields, drone's aerospace photography technology is further changing our cognition of aerospace images. They bring a new perspective to the shooting of aerospace images, and show unparalleled flexibility and convenience. At the same time, the application of aerospace photography has further improved the accuracy of cartography and mapping, providing us with a more comprehensive and in-depth window to understand the universe.
For example, in a recent drone aerial news, DJI released a prime lens group with its own DL mount, four of which have the same size, filter size, and weight for the DJI Ronin 4D full-frame size movie machine. This series of lenses offers a constant F28 large aperture, uses 16 sets of 23-piece structures, including 5 ED lenses and Super ED lenses, has low dispersion characteristics, and uses Nano-GI coating technology to provide shooting results comparable to the flagship XF telescopic zoom lens.
In the space shooting of drones, we can see that the improvement of drone's flight control technology and sensor technology, the research of autonomous navigation and path planning algorithms, and the combination of artificial intelligence and big data analytics technology have all provided strong technical support for space shooting. The flight safety and adaptability of drones to harsh environments have also been further improved, making the application of drones in space shooting gradually become a trend.
1. Fixed-field lenses: In aerial photography, fixed-field lenses are usually used to quickly attract the audience's attention. Fixed-field lenses often use wide-angle or ultra-wide-angle lenses, which can capture a wider landscape or scene, allowing the audience to feel a stronger visual impact.
2. Revealing lenses: Revealing lenses display the scene like opening a gift slowly, usually using medium or telephoto lenses, which can capture more delicate details or farther scenes, allowing the audience to experience a richer visual experience
3. Through the lens: Through the lens is through the fixed scene, usually using a wide-angle or ultra-wide-angle lens, which can capture a wider scene and make the audience feel a stronger visual impact.
4. Flying lens: The flying lens is to fly over the building, usually using a telephoto or ultra-telephoto lens, which can capture farther scenes and give the audience a stronger visual impact
5. Base lens: The base lens is shot vertically at the target subject, usually with a wide-angle or ultra-wide-angle lens, which can capture a wider scene and give the audience a stronger visual impact.
6. Fog through function: Fog through function can enhance image quality, especially important in rainy, humid and night shooting, allowing the drone high definition camera to shoot clear images in harsh environments.
7. Noise reduction function: The noise reduction function can eliminate noise, which is especially important in night scene shooting, allowing the drone high definition camera to shoot clear images in low light environments.

8. Day and night automatic switching function: The day and night automatic switching function can provide clear monitoring images under different lighting conditions, which is of great significance in aerial photography, search and rescue, agricultural plant protection and other fields
9. Pixels, optical sensors, lenses, stability and other key factors: These factors determine the imaging quality and shooting effect of the drone high definition camera, and need to be considered when choosing.
10. Tips such as adjusting the camera angle, previewing, and paying attention to the environment and storage capacity when shooting: These tips can help the drone high definition camera play its role better and shoot better works.

Why do images presented by a lens have optical aberrations?A. DistortionDistortion will cause real objects to be straight lines, but in photos to be non-straight lines, to be curved lines.a) barrelb) pincushionc) complex/wavyTypes of lenses prone to distortion: usually zoom lenses and wide-angle lenses.B. Field curvatureFor plane objects in reality, after imaging, the real image surface is curved, and most actual sensors are also flat, which will cause the center field of view and the edge field of view to be unable to present clear images at the same time.Lens types prone to field curvature: usually wide-angle lenses and large aperture lenses.C. Vignettinga) Vignetting-----Light FalloffUneven brightness Light Falloff, the exposure of the center field of view and the edge field of view are different, resulting in inconsistent brightness between the center and edge of the picture, which is what we often call the camera vignetting problem.b) Vignetting-----Color CastUsually there is a color difference between the edges of the picture (especially the corners) and the center area. It is not entirely caused by lens aberration, filters and sensors will also have a certain impact.Types of lenses prone to vignetting: usually largeThere are many factors that cause optical aberration in lenses, some of which have been shared above:1) distortion2) field curvature3) Vignetting ---Light Falloff4) Vignetting ---Color CastIn fact, there are some other influencing factors:1) Focus ShiftWhen you reduce the aperture size, the best focus plane will move to the front or back. That is, the aperture size will affect the best focus plane position, which is what we call focus shift.Common lenses that are prone to focus shift: large aperture lenses. When adjusting the aperture, the focus usually needs to be re-adjusted.2) Onion ring bokehThere are some out-of-focus circular rays of light in the optical path of the lens, which is generally caused by a defective lens.Common lenses that are prone to "onionrings": Some large aperture lenses often use aspherical lenses because of the flatness of the surface involved during processing.3) Flare-GhostingWhen there are some abnormal colored patches in the presented image, usually like colored circles or colored blocks of specific shapes, we become ghost images.Common ghost images: zoom lenses, lenses with a large number of lenses, and large-diameter lenses. During processing, try to reduce the aperture as much as possible, or use post-image processing.4) Flare-Internal ReflectionsGenerally speaking, highly reflective objects inside the lens, such as structural parts with too high reflectivity, or dirty lenses in the optical path, etc. In most cases it is caused by workmanshipissues.Common internal reflection stray light lenses:especially large aperture lenses, during the production process, you can try to eliminate light, cut off light, block stray light, increase transmittance, and reduce the aperture as much as possible when conditions permit.
