Deep Image Digital X Photographic System
There were many digital X-ray photography systems in Deep Image. For example, Deep Image's Sontu100 -FMDR was a digital X-ray photography system produced in Guangdong, and it was used for medical purposes. It had the characteristics of a digital X-ray machine and was the product of the combination of computer digital image processing technology and X-ray radiation technology. On the basis of the original direct film imaging of the original diagnosis X-ray machine, real-time image digital processing was carried out through A/D conversion and D/A conversion to achieve digitization. Its advantages include clear image quality, fast imaging speed, less radiation than traditional X-ray machines, etc. The flat plate size is greater than or equal to 14 "×17", the type of flat plate is non-crystalline, the detector's pel size is 140um, and the maximum spatial resolution is 510kHu. There was also a new generation of portable digital X-ray imaging system from Deep Image. It was made up of an advanced waterproof and dust-proof IP54 grade a-Si flat-panel detector and the Sontu Smart -VR series digital image acquisition and imaging system, combined with a domestic 8-kilogram combined head and a flexible mechanical structure. It was mobile, easy to operate, and had low radiation. For example, its combined head solved the space layout limitation of the portable VR, and it used an 8-inch liquid crystal display screen for sensitive operation. The overall body is flexible and suitable for a variety of scenarios. The flat panel detector is waterproof and dust-proof to avoid cross-infection. It has a contrast balancing algorithm based on the human visual system, MMOPA, to provide high-quality images. Read more exciting novels for free
Photographic cartoon image
There were many forms of expression and related technical means for photography and animation images. On the one hand, special effects could make real people appear in anime images in photos. For example, anime special effects could make use of the perfect characteristics of the paper characters in the anime to satisfy the public's fantasy of a beautiful image, transforming the real person into an anime image with big eyes and high looks. This kind of special effect photo could also hide one's true appearance and increase the sense of mystery. Coupled with the publicity of the online platform, it made it popular. On the other hand, a CG face selfie had both the characteristics of a real human face and a virtual 2D image. It could present a near-perfect anime feeling while retaining the original appearance of the character. In terms of photography equipment, Canon and other brands of cameras (such as Canon 5D Mark IV, Canon 60D, etc.) could be used to capture images during shooting. Different aperture, exposure time, USB, focal length and other parameters would affect the final imaging effect. These devices could be used to shoot scenes or characters related to anime images, such as shooting the streets of Tokyo with anime scenes. The shooting data could provide raw materials for the creation of anime-related photography works. In addition, in some commercial scenes such as cruise ships, the staff would dress up as cartoon characters to attract tourists to take photos. This was also a manifestation of the image of photography animation in commercial photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Using the search engine, enter the keyword " photography background board ", and you can get a variety of photography background board pictures, including pure color background boards, background boards with specific patterns or scenes, etc. For example, pure white, black, and gray background boards are suitable for portrait photography to highlight the main body; background boards with flowers, fairy tale scenes, etc. can be used to create different atmosphere. 2. He searched on photo material websites. These websites often had categorized background pictures for photography. For example, there were different types of background picture resources for portrait photography, children's photography, commercial photography, and so on. It was convenient to filter according to their needs. 3. If it was a specific type of photography background board, such as a retro style background board used for portrait photography, you could enter a more precise keyword " retro style portrait photography background board " to narrow the search range to get a more suitable picture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the best choice for the quality of the photographic image?
In photography, if you wanted better quality, you could consider the following aspects: ** 1. Aperture ** 1. He avoided using the extreme aperture of the lens. If the aperture was too large, it would make the blurring out of focus too strong, resulting in a decline in image quality, and when the aperture was used to the minimum, the image quality would also be reduced. For most high-quality lenses, reducing the maximum aperture value by one to two levels can get better image quality. For example, if the maximum aperture value of the lens is f/2.8, f/4.0 or f/5.6 aperture may be the best. 2. The best aperture was usually the largest aperture reduced by 2 - 3 stops. Shooting at this aperture helped to get good quality. ** 2. In terms of light sensitivity (USB)** 1. The lower the sensitivity, the less noise the picture had, and the purer the picture quality. Generally, a sensitivity of around 800 had little effect on the image quality, but after exceeding 800, the image quality would be affected more obviously. 2. In the case of insufficient light, if you want to maintain a low sensitivity to ensure image quality, you can use a large aperture or slow down the shutter speed (but when using a slow shutter, you need to pay attention to stabilizing the camera, such as using a tripod) to ensure normal exposure. ** 3. In terms of filter ** 1. The quality of the filter will affect the quality of the image. Don't choose a cheap filter just to protect the lens. You should try to buy a better quality filter. If you can't buy a high-quality filter, it's better not to use a filter. ** 4. The stability of the shooting equipment ** 1. When using a tripod: - Try to use the shutter release or remote control to shoot. If you don't have it, you can use the time-lapse function of the camera to avoid the vibration caused by the shutter. - For lenses with anti-shake function, the anti-shake function should be turned off when shooting with a tripod to prevent the anti-shake component from affecting the image quality. - If it was a single-lens reflex camera, it should also use the mirror pre-lift function to reduce the impact of the slight vibration caused by the mirror rising on the image quality. 2. Hand-held shooting: - The correct hand holding posture helped to improve stability. Use both hands together. Hold the camera handle with your right hand, hold the zoom or focus ring of the lens with your left hand, and hold the lens with an angle between your hands. When using the vertical composition, rotate the camera 90 degrees counterclockwise, hold the camera with your right hand, and press the shutter with your index finger. When shooting, clamp your upper arm tightly, relax your lower arm, and place your arms one in front and one behind. - The standing posture was also very particular. One foot in front, one foot behind, thighs tight, calves relaxed, to prevent the body from shaking and causing the photo to blur. - The heartbeat and breathing would cause the camera to shake slightly when the shutter was pressed. You could take a deep breath to stabilize yourself first, then hold your breath when you press the shutter to minimize the shaking. - The anti-shake system should be turned on when the camera is held and the lens or body has anti-shake function. In theory, anti-shake can effectively increase the shutter speed by two or more levels. - If you don't have a tripod, you can find something to rely on to help you shoot, such as leaning against a stone, tree, wall, etc. For a long exposure time, you can put the camera on a camera bag or on a stone, table, etc. ** 5. The format for saving photos ** 1. You can choose to save the photo in the raw format, which can record the optical information of the photo file to a great extent, providing a wide space for post-production. When the photos were over-exposed and dead black, there was a lot of room for post-production software to adjust them. Moreover, the automatic white balance, color temperature, and other parameters could be used during the shooting, and then the software could be used to flexibly adjust them later. 2. Some cameras had a compressed version of the RAW format. Although the file size was small and saved memory space, there would be some loss of image quality (but not obvious). It could be selected according to personal circumstances. 3. You could also save it in JPG + RAW format. This way, you could view the photos in JPG format when you needed to quickly browse through them. After determining the photos you wanted to post-process, you could find the corresponding photos in RAW format according to the serial number for post-processing. However, this method required a slightly larger memory card space (such as 128G). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic equipment maintenance system
The following is a photographic equipment maintenance system: ** 1. Cleaning ** 1. ** Cleaning tool selection and precautions ** - Cleaning the photographic equipment should use suitable tools, such as air blowing, lens cloth, lens cleaner, cotton swabs, wet towels, etc. It is strictly forbidden to use mouth blowing, finger wiping, or other unprofessional tools to avoid scratches or pollution. - Cleaning liquids, wet towels, and other cleaning supplies should not be overused, and expired or deteriorated cleaning tools should not be used. 2. ** Cleaning sequence and steps ** - Cleaning should be done in a certain order, generally from outside to inside, from big to small, from light to heavy. - Cleaning the camera body: First use the air to blow off the dust and hard particles on the surface, then wipe the entire surface of the camera body with a wet towel. For parts that are difficult to clean, such as gaps and bayonet, you can use cotton swabs and cleaners for fixed-point cleaning. - Cleaning the lens: First use air to blow off the dust and hard particles on the lens, then use the lens cloth and lens cleaner to carry out a deep cleaning. Wrapped the cleaning cloth with lens agent on your fingers, and then wiped the lens from the center of the lens in the same direction at a constant speed. For lenses that are deep inside the bayonet, you can use a microfiber lens cloth wrapped in a cotton swab to clean them. - [Cleaning of the sensor: It must be done in a dust-free environment and must be done very carefully.] First, check if there is any dust or stain on the sensor (set the camera to full aperture, the highest IS value, manual focus infinity, and take a photo against a pure white background. Then, enlarge it to check if there are any black spots). If there is dust or stains, you can use a professional sensor cleaning kit to gently and quickly wipe it according to the instructions. If you are not sure if it can be operated, you should send it to a professional after-sales service. At the same time, cleaning should be avoided in a strong wind or dusty environment. Do not spray any liquid directly on the camera or lens (indirectly). ** 2. Storage ** 1. ** Storage location and container selection ** - The photographic equipment should be stored in a suitable place and container, such as a waterproof box, a waterproof cabinet, a sealed box, etc. Do not place the equipment in direct sunlight, high temperature, high humidity, electromagnetic interference, or dusty places. 2. ** Storage method and posture ** - Storage: Turn off the camera and remove the battery (if not used for a long time). Place it in a waterproof box covered with a soft cloth or styrofoam. When possible, the camera could be stored together with the commonly used lens, and a U-shaped inner lining layer (foam board would also work) could be added to the connection to support the lens. - Single lens storage: Lock the lens hood upside down and cover the front and rear covers. Place the lens upside down in a separate space in the moisture proof box. At the same time, he adjusted the focus ring to infinity and shrunk the zoom lens to the shortest position, fixing it with the lock button. - Storage of batteries: Batteries of different brands or models cannot be mixed or stored together, and the humidity in the moisture proof box or cabinet should be checked regularly (generally, it is recommended to store them at a humidity of about 50%). If the moisture absorption card or the drying agent is used, it must be replaced or disposed of in time; if the electronic moisture proof box or moisture proof cabinet is used, it must be powered on at all times to avoid power failure. ** 3. Protection during use ** 1. ** Screen Protection ** - It was to prevent fingers from touching the lens to prevent fingerprints and grease from affecting the paint coating and imaging of the lens. avoid contact with saliva or water stains, and avoid contact with pink gloves (during daily shooting, it is recommended to use bare hands or gloves that have never touched the patient). Move quickly when changing the lens, avoid the wind and dust, and cover the lens cover in time when not in use. The lens can be protected by adding a UV-lens (Ultraviolet filter) and a hood. 2. ** Airframe Protection ** - Water Repellent: When water flows into the interior of the camera, it is easy to cause a short circuit. The temperature difference is easy to produce condensation. When shooting in low temperature environments, it is recommended to wear a cold-proof thermal cover for the camera. When the camera is not in use, put it in a special drying box or place a drying agent in the locker to avoid moisture. - [Protect from dirt: Move quickly when changing lenses. Face the camera down. Pay attention to avoiding the wind to prevent dust from entering the camera.] Do not wear pink gloves during daily clinical imaging, and do not cross infect the patient. - Shock absorption: When shooting, try to hang the camera around your neck to prevent the camera from falling due to instability. When placing the camera, find a stable place to place it to prevent the camera from falling off due to unstable support. - LCD screen protection: To prevent the color LCD screen from being scratched by hard objects, you can consider using a protective sticker. - Protection of the camera card: Do not hot-plug it, do not plug the camera card when it is turned on, so as to avoid damage to the digital products and data loss. It was recommended to have an extra camera card, just in case. A large number of clinical images were recorded in the camera card, and it was necessary to develop the habit of backing up regularly. When the memory card is not in the camera, pay attention to prevent bending, to avoid falling and heavy blows. When inserting the camera card, aim at the card slot. Don't be violent or impatient. Don't damage the card slot interface or bend the camera card pin. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The application of photographic optical system
Photographic optical systems were widely used in many fields: ** 1. The field of photography ** 1. ** Create a work of art ** - In landscape photography, the photographic optical system could adjust the focal length, aperture, and other parameters of the lens to capture the vast scenery or close-up local scenery. For example, using a wide-angle lens (small focal length) could capture a grand mountain scenery, and a large aperture could create a shallow depth of field effect, making the front clear and the background blurred, thus emphasizing the main elements in the picture. - In portrait photography, the optical system helped to shape the character. Through the appropriate focal length of the lens (such as a medium telephoto lens), the appearance of the character could be beautified to a certain extent. At the same time, the details of the character's face could be accurately presented by focusing. The aperture control depth of field separated the character from the background, enhancing the layering of the picture. - In documentary photography, the photographic optical system could quickly and accurately focus and image, recording real social scenes. 2. ** Daily photography ** - For ordinary photography enthusiasts, whether it was a mobile phone or a camera, the built-in photographic optical system could meet the needs of daily recording of life scenes, travel souvenirs, and so on. ** 2. Film industry ** 1. ** Creation of visual effects ** - Cinematographers use different lens characteristics, such as different focal lengths, apertures, aberrations, and other optical characteristics to create unique visual effects. For example, using a telephoto lens to compress space, making the scene in the picture look closer than the actual distance, or using a fisheye lens to create an exaggerated distortion effect, bringing an immersive viewing experience to the audience. ** 3. Medical field ** 1. ** Endoscopy ** - The optical imaging system was a key part of the telescope. It could transmit images of internal organs. By using a miniature optical lens in the microscope, doctors could clearly observe the pathological changes of internal organs such as the digestive tract and respiratory tract. Moreover, this optical imaging had a high resolution, which could help doctors find small diseases. 2. ** Skin Examination ** - Some optical imaging techniques could perform high-resolution imaging on the skin to observe the changes and texture on the skin surface, providing a basis for the diagnosis of skin diseases. ** 4. Research Field ** 1. ** Astronomical Observation ** - In the large optical system of the astronomical telescope, the faint light emitted by distant celestial bodies was collected through a huge lens or mirror. Through the focusing and imaging process of the optical system, scientists could study the shape, structure, and other information of celestial bodies. 2. ** Bioimaging ** - The optical microscope was a commonly used tool in biological research. It used the principle of optical imaging to observe the microscopic structure of biological cells and tissues. For example, a fluorescence microscope uses a specific optical system to stimulate fluorescent labels to emit fluorescence, thereby locating and studying specific molecules or structures within the cell. ** 5. Security Surveillance Field ** 1. ** Video Surveillance ** - The optical camera was used for video surveillance in security monitoring. Through the imaging function of the optical lens, real-time monitoring of specific areas was carried out to ensure the safety of public or private areas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Deep Space Photographic Refraction Mirror Astronomical telescope
The following are some of the commonly used refraction telescope recommendations for deep space photography: - [Startron 80EQ: Refraction type, focal length 900mm, relatively affordable, a good choice for entry-level astronomy enthusiasts for deep-space photography.] - [Startron 80DG: Refraction type, focal length 910mm, good performance in terms of image quality, etc., can meet certain deep space photography needs.] When choosing a telescope for deep-space photography, many factors needed to be considered, such as focal length, aperture, price, optical quality, and so on. A telescope with a longer focal length could obtain higher magnification, but it also required a more stable stand. The larger the aperture, the stronger the ability to collect light, and the brighter and clearer the image. However, the size and weight of the telescope would also increase, and the cost would also be higher. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Digital Life Fortune Telling System
The Digital Life fortune-telling system was related to Numerology. Numerology included many methods. For example, Pythagorean Numerology, whose origins could be traced back to 569 - 470 B.C. Pythagoras believed that any number could be simplified into a single digit between 1 and 9, and understanding this single digit would help one understand their spiritual and magical vibrations. Kabbalah Numerology used the 22 letters of the Hebrew Alphabet to explore the meaning of the numbers in names. Each letter was assigned a number, and the numbers were added together to gain insight into the direction and purpose of life. Chaldean Numerology focused on the vibrations of the numbers 1 to 8. The number 9 was regarded as sacred and represented a connection with the divine. Destiny was calculated by the date of birth and the numbers associated with the letters of the name. There were three important factors in computational numerology: birth number, life number, and fate number. The birth number could be calculated according to the date of birth. If the person was born on the 5th day, the birth number would be 5. If the person was born on the 28th day, the birth number would be 10. The life number could be obtained by adding the date of birth and gradually reducing it. This number revealed a person's " nature," uniqueness, and " karmic debt." The calculation method of the number of fate was similar to the number of life. It revealed the inner desire and the desire of the soul in this life. When calculating, the letters would be represented by specific numbers. However, it was important to note that fortune-telling often lacked scientific basis and was often unreliable. For example, street fortune-telling might use ambiguous words, and the so-called " secret can't be revealed " might just be a cover.
