Oblique composition in photography
Oblique composition was a special method of composition in photography. It was often seen as the opposite of the golden ratio, the tic-tak-toe method, and the three-point method. I. Use in portrait photography 1. ** Creating emotions ** - It can create emotions such as uneasiness, horror, violence, drunkenness, depression, rebellion, etc. It is used to express the beauty of emotions and excavate the beauty of deep details. Excellent photographers often use this to express their changing emotions. 2. ** Shooting Techniques ** - ** Straightening the body, tilting the frame **: Change the angle of view when shooting, or reserve space for the composition of the second crop in the early stage and later stage. - ** Tilting the reference object **: Using objects with obvious lines such as doors, windows, and railings as a reference, the background or the front line of the composition is slanted. - ** High elevation, high elevation **: By shooting from a low or high point, the picture has a sense of depth, which is more refreshing than shooting from a head-up angle. - ** Tilting composition to the left and right **: When there is no suitable reference object, you can tilt the composition to the left or right. - ** Make the picture upside down **: Shooting from top to bottom at a 45° or 90° angle can create a visual pressure. Second, applications outside of portrait photography 1. ** Shooting buildings and still life ** - It could show more space, especially when the focal length of the lens was not enough. - Using regular lines to create a sense of movement, expressing the gradual tension and dynamic nature of the lines. - Turning the still life space upside down to create an unusual artistic conception. - It can be combined with diagonal composition to form a structural aesthetic by placing the main body on the diagonal. Third, the slanted composition of the design 1. ** Overall Tilting **: Tilts all the elements of the picture to increase the dynamic feeling and visual attention. 2. ** Tilting Main Image **: Tilts the main image in a symmetrical image to widen the space to highlight the main image. 3. ** Tilted text **: The main body is not moved, and the title text is tilted to enhance the emotional effect of the image. 4. ** Tilting Elements **: Tilting the elements in the picture and matching them with diagonal titles to make the picture more powerful. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to generate oblique photography data
There were the following steps to generate oblique photography data: 1. Collect image data: Collect a large number of aerial images and ground images to build a model of objects in the real world. It can be collected through drones, airships, and other devices, or through satellite technology. 2. Setting control points or ground feature points: Before image processing, set some control points or ground feature points as reference points. Their coordinates need to be measured and recorded in advance. You can use tools such as the global positioning system (GPS) to measure them. The control points were used to transform the geometric coordinates, and the ground feature points were used for feature extraction and matching. 3. Carry out the geometric coordinate transformation: According to the control point coordinates, use methods such as the Eulerian angle transformation and the camera internal and external parameters (six parameters) transformation to carry out the geometric coordinate transformation, correct the attitude and elevation information in the image, and obtain a unified local coordinate system for all images. 4. Character extraction and matching: perform feature extraction and matching on the image to identify objects and structural information. The features include edges, corners, texture, etc. The matching is based on similarity measurement and geometric constraints. It can be achieved using computer vision algorithms such as SIFT, Surf, ORB, etc. 5. Generation of three-dimensional model: A rough three-dimensional model was generated based on the feature extraction and matching results. Then, it was further optimized and corrected by three-dimensional reconstruction algorithms such as triangulation, voxel-gridding, and point cloud registration to better reflect the shape and structure of objects in the real world. 6. To export the 3D model data of the local coordinate system: According to the previous geometric coordinate transformation, the generated 3D model data is converted into the coordinates of the local coordinate system. This can be achieved by multiplying the coordinate transformation matrix of the local coordinate system and the local coordinate system. The imported data can be in the format of ObJ, STL, Fold, etc., for urban planning, land management, virtual reality, and other applications. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to deal with the shadow of 3D oblique photography
In 3D oblique photography, the following methods could be used to deal with shadows: ** 1. Use ray tracing technology and adjust the light source ** 1. ** Ray tracing technology ** - You can use ray tracing to create realistic shadow effects. This technology could more accurately simulate the transmission, reflection, refraction and other physical phenomena of light, thus making the shadow effect more realistic. 2. ** Adjusting Light Source ** - By adjusting the position and intensity of the light source, the shadow effect could be improved. Changing the position of the light source could change the direction and length of the shadow, and adjusting the intensity of the light source could affect the depth of the shadow. ** 2. Dealing with shadows related to colors and materials ** 1. ** Shadow processing in uneven or distorted colors (related to color)** - If the color of the shadow is uneven or distorted, it may be caused by the lighting conditions during the photography process or the color adjustment of the photographic equipment. Image processing software could be used to refine and adjust the texture of the model. For example, color balance, contrast, brightness, and other parameters could be adjusted to improve the color equality and realism of the shadow. 2. ** Shadow processing in color tone discrepancy (related to color)** - If the color tone of the model did not match the actual scene (including the shadows), it might be caused by the incorrect white balance setting during the photography process or the color correction problem during post-processing. You can use professional color calibrators to perform calibrations based on reference objects or color cards in the actual scene. You can also perform partial or overall toning on the model to approximate the hue of the shadow in the actual scene. 3. ** Shadow processing when material and texture are not realistic enough (related to material)** - Due to the limitations of the camera angle and lighting, the material and texture of the model may not be able to completely reproduce the shadow effect in the actual scene. You can try to use higher-quality texture images or increase the details of the texture. You can also use professional texture processing software to increase the material effect and realism of the shadow part of the model. ** 3. 3D Tilting Model Based Shadow Toning Method ** 1. ** Confirm Shadow Area ** - After the three-dimensional scene reconstruction is performed according to the multiple two-dimensional images to generate the three-dimensional tilted model, the multiple illumination directions are respectively determined according to the shooting time and shooting location of the two-dimensional images, and the three-dimensional tilted model is respectively projected in parallel along the illumination directions to obtain the illumination depth map. Then, according to the field of view of the two-dimensional image, the camera position, and the illumination depth map corresponding to the illumination direction, the shadow area of the three-dimensional tilted model under the perspective of each two-dimensional image was determined. 2. ** Toning ** - performing toning processing on the shadow area of the determined three-dimensional tilt model under the perspective of each two-dimensional image to obtain the target three-dimensional tilt model. The illumination direction can be determined by calculating the sun elevation angle and sun orientation angle corresponding to each two-dimensional image, and then the illumination direction can be calculated. Obtaining the illumination depth map includes the steps of performing parallel projection on each triangular surface in the three-dimensional inclined model to obtain an initial depth map, determining a point set corresponding to the middle point surrounded by the triangular surface and calculating the depth value, and finally generating a target depth map. ** 4. Traditional manual processing method (there are certain drawbacks)** 1. ** The shadow is determined by visual interpretation ** - After the 3D tilted model was reconstructed, the parts of the 3D tilted model that were affected by the shadow were determined by the engineer's visual interpretation. 2. ** Manual modification of texture ** - The engineers manually modified the texture of the parts affected by shadows in the 3D tilted model, but this method was highly subjective. Different designers might have different processing methods, and the results might be different. It was also time-consuming and laborious. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Jewelry photography method
Here are some ways to take photos of jewelry: 1. ** Selection of lens and equipment settings ** - ** Use of lens **: You can use a macro lens, such as the EF100mm f/2.8L Macro IS USM or the RF100mm f/2.8L Macro IS USM, which can capture the details of the jewelry and highlight the designer's creativity. - ** camera parameters **: to make more images focus, you can use a small aperture, such as f/22 for deep depth of field; the shutter speed is usually set to 1/100; the camera should be installed on a tripod to prevent hand shake from blurring the photos. For black gemstone images, you can use multiple light sources to create layering, and you can also use a mask to create striped lighting patterns on a lamp to increase its attractiveness. If you lack ideas when shooting, you can find inspiration from magazines or Social networks and try to copy the photos. At the same time, determine the position of the light source and the angle of the shot. 2. ** Reflective treatment ** - ** Control of the environment **: Since the surrounding light will affect the reflective surface and the color temperature of the jewelry, the studio should be kept dark and the degree of light reflection should be adjusted by controlling the lighting. - ** Reflecting Plate and Diffuser Usage **: White reflecting plate can reflect the light back to the jewelry and hide the surrounding objects; correct positioning of black or white reflecting plate can eliminate the reflection of flat gold jewelry; Diffuser can reduce the reflection of metal surface, and the position of the reflecting plate should be close enough to the subject to make the light softer. 3. ** Jewelry arrangement and composition ** - ** Clear focus **: When shooting jewelry, you need to be clear about the focus of the accessories, which will affect the appearance, mood, and composition of the image. - ** Backgrounds and props **: The background and props should be kept simple so that the lighting can best show the elegance of the jewelry. For color selection, you can consider the depth of the jewelry's color tone, choose complementary colors to create a harmonious appearance, or use cool colors to make the jewelry stand out. 4. ** Shooting Techniques ** - ** Choosing the shooting angle **: It is important to observe every corner of the jewelry before shooting. Different angles will make the diamonds look different. When drawing the lighting plan, you need to pay attention to each part of the jewelry. - ** Increase the image dimension **: Can take photos with reflections. The reflections can add luster to the accessories, making the picture more perfect and making the jewelry shine. - ** Model display (option)**: Arrange a model to display the jewelry on the body. This will help to show the jewelry's decorative effect to potential buyers and increase sales. - ** background selection **: You can use a background of the same color as the gem to make its color stand out. In addition to choosing a specific color to make the gem stand out, using a black background will help the image stand out and fully display the gem's color. If you take a photo of gold jewelry, choose a high-contrast color (such as red or blue background) to help highlight the gold color. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
macro photography method
Here are some macro photography methods: - ** Choice of angle **: For example, when shooting insects, you can find a unique angle to highlight the main features. For example, when shooting damselflies, you can highlight their big eyes and find a suitable angle to express the photographer's feelings. - ** Picture composition technique **: In terms of composition, you can use the line composition method. Let a line run through the picture and embellish it with insects. For example, use vines as rhythmic lines. When the insects climb to the appropriate position, you can shoot them to make them look cute and beautiful. - ** Shooting timing **: If the subject is insects, which are easy to fly away, you can choose to go out and shoot around 5 a.m. At this time, most insects have not started to move, so it is easy to shoot. - ** Using the camera's characteristics **: - ** Use macro lens **: Professional macro lens has its unique advantages. Its image sharpness is extremely high, with a 1:1 or higher magnification. The closest focusing distance can reach 30mm-50mm. It can shoot at a close distance to enlarge the details and show a new microscopic world. In addition to macro, it can also take into account various subjects such as skits and portraits. - ** Consider lens replacement **: Close-up lenses can be installed in front of the lens as a replacement for macro lenses, but the image quality will be reduced and the control will be more complicated. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Huawei's photography method
Here are some ways to take photos with Huawei phones: 1. ** Professional Mode ** - ** Adjusts the sensitivity of the image to a certain degree. ** In dimly lit environments, you can increase the sensitivity of the image to increase the brightness and clarity of the image. However, if the sensitivity of the image is too high, it will cause noise. For example, in a dimly lit coffee shop, you can adjust the USB from the default 100 to 400 or 800, but avoid setting it too high. - ** Shutter Speed Control (S)**: The shutter speed determines the time that the camera's sensor is exposed to light. A slow shutter speed (e.g., 1/4 second or longer) could be used to capture the silkiness of flowing water or the trajectory of stars; a fast shutter speed (e.g., 1/1000 second) could be used to capture instantaneous movements, such as a child's smile or an athlete's movements. - ** Choose the focus mode (AF.)**: Huawei mobile phone cameras provide single autofocus (S-AF.) and continuous autofocus (C-AF.). Single autofocus was enough for shooting still objects; when shooting moving objects, such as running children or flying birds, continuous autofocus ensured that the photos were clear. - ** White balance adjustment **: White balance is related to the color reproduction of photos. You can use the built-in white balance options such as sunny days, cloudy days, fluorescent lights, etc., or manually adjust it. In an environment with complex lighting, manually adjusting the white balance would help to get a balanced and natural photo. 2. ** HPR function **: The High Dynamic Range (HPR) function can increase the dynamic range and details of a photo by taking multiple photos with different exposure levels and combining them into one. In scenes with strong light contrast, such as when shooting against the light, turning on the HPR function could preserve the details of the light and dark parts of the photo, making the photo look more harmonious and natural. 3. ** Continuous shooting function **: Long press the shutter or volume button to shoot multiple moments in a row. It is suitable for capturing fleeting scenes, such as a child's first smile, an athlete's sprint, etc. After shooting, you can choose the most exciting photos from the gallery. 4. [Timed photo and voice-activated photo: These two functions bring more convenience and fun to shooting.] 5. ** Using the front camera function of the phone (Take the Huawei nova 12 Pro as an example)** - ** Portrait Engine **: For example, the XD Portrait Da Vinci Portrait Engine on the front of the nova 12 Pro can improve the light and shadow effects and skin texture of the portrait. - ** Choose portrait beauty theme **: You can choose different portrait beauty theme according to your needs to satisfy different effects such as exquisite reality or atmosphere. - ** Free zooming **: With the free zooming function in the front, you can take pictures of people and scenery at 0.7x, close-up of faces at 2x, and makeup at 5x. 6. ** Using the phone's rear camera function (Take the Huawei nova 12 Pro as an example)** - ** Aperture adjustment **: For example, the second-generation physical iris system of the rear lens of the nova 12 Pro. The F1.4 portrait circle is used to capture the layered background and atmosphere; the F2.0 landscape circle is suitable for shooting static scenery and moving people; the F4.0 aperture can make the front and back clear, suitable for shooting party scenes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

supplementary light deviation method in photography
Here are some ways to fill in the light: ** 1. Use different tools to fill in the light ** 1. ** Reflecting Plate Replenish Light ** - Reflective panels had silver, gold, white, and black surfaces (light absorbing panels), as well as soft screens with different functions. The silver surface reflected strong light and reflected white light, which was suitable for making up for shadows when the sun was strong; the gold surface reflected high light and reflected warm light, which was suitable for subjects that needed the skin of the characters to be warm; the white surface reflected weak light but was soft, which was good for showing the details of the skin; the black surface was used to absorb some light when the three-dimensional feeling was needed; and the soft light screen was used to filter the light when the light was hard to make the skin delicate. When taking photos of people, even if there was no shadow on the face but no spirit in the eyes, the reflective board could be used to fill the light to create the eye light. 2. ** Soft Light Box Replenishes Light ** - The softbox diffused light to soften the light and reduce the contrast between shadows and highlights. It was suitable for portrait photography and product photography to create a natural and soft light effect. 3. **LED fill light ** - The LED fill light was small in size, light in weight, and easy to carry. It was suitable for outdoor shooting and video shooting, and usually had the function of adjusting brightness and color temperature, which could flexibly adjust the light effect according to the shooting needs. ** 2. Techniques to fill in the light from different angles ** 1. ** Positive light ** - Placing the light source directly in front of the main body could evenly illuminate the entire main body and reduce shadows. It was suitable for most shooting scenes, but the picture was easy to appear dull and lacked a three-dimensional sense. 2. ** Side fill light ** - Placing the light source on one side of the main body could enhance the three-dimensional effect and texture effect of the main body. It was suitable for portrait photography and still life photography. Through the change of the side light, the outline and details of the main body could be highlighted. 3. ** Backlight ** - Place a light source behind the main body to create a backlit effect, making the outline of the main body clearer. In order to prevent the front of the main body from being too dark, a supplementary light source could be added in front to balance the front and back light. It was often used for silhouette photography and scenes that created a dreamy atmosphere. 4. ** Top-fill light ** - Place the light source above the main body to simulate the direction of natural light, so that the light is evenly distributed on the main body, reducing shadows. It is suitable for indoor photography and product photography. 5. ** Light at the bottom ** - The light source was placed below the main body to eliminate the shadows caused by the light from above. It was rarely used alone and was usually used in conjunction with other light sources to achieve a better fill light effect. In portrait photography, the indoor soft light box can be used as the main light source, with the side of the reflective board to fill the light; outdoors, natural light can be used as the main light source, and the LED fill light can be used to fill the light. In product photography, the top of the product is illuminated by a soft light box, and the front light of the reflective plate can reduce the reflection and shadow of the product surface; when shooting metal or glass products, the side light can enhance the texture and luster. When shooting portraits at night, the light can be aimed at the person from the side at about 45 degrees to form a silhouette light (it is best to use warm light), and the face can be filled with light from the side at about 45 degrees to make the face more three-dimensional. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
