Books on photography and photography techniques
Personal photography, travel photography
The following are some of the key points related to personal photography: ** 1. Initial preparations ** 1. ** Costume matching ** - They had to choose suitable clothes according to the different scenery. For example, in a small and refreshing scene like the rape field, it was better to wear light-colored, casual clothes. It was more appropriate to avoid red and purple, high-end and stylish clothes, such as white T-shirts and blue denim overalls. At the same time, the matching of clothing should consider the coordination with oneself and the environment, including makeup, styling, and so on. 2. ** Equipment preparation ** - Cameras or mobile phones could be used for travel photography. If you used a camera to take a selfie, you might need to buy an additional remote control. Some cameras could be connected to the phone through Wifi, and you could see yourself in the camera in real time on the phone screen for composition. The phone also had a variety of selfie functions, such as timed shots (the Glory 30S phone's photo page had "2 seconds, 5 seconds, 10 seconds" options), voice-activated photos (useful in quiet environments), and smiley face shots (better lighting, more practical within 5 meters). ** 2. Techniques and taboos during filming ** 1. ** In terms of composition ** - To avoid taking pictures from the hands, feet, and joints of the subject. When setting up a selfie, set up the tripod, put the camera or phone on, and adjust the camera position and composition. For example, when you want to be a part of the scenery or take a photo at a scenic spot, you can set a delayed selfie or even continuous shooting to adjust the ideal composition. - Pay attention to the position of the character in the picture, avoid being rigidly in the middle of the picture, and make the character and the background form an organic whole. - If there are horizontal lines (such as the sea, the lake) or the horizon (such as a sea of flowers), avoid these lines crossing the main parts of the character (such as the head and neck). If it is unavoidable, try to move the horizontal line below the shoulders of the character. 2. ** Selection of background ** - When taking portraits, the background should be carefully selected and the scenery with local characteristics should be used as the background, but the background should be avoided. If too many elements entered the picture, it would make people dazzled and lack highlights. The background color had to be unified so that it could better highlight the characters. 3. ** Face and posture ** - If his expression and posture were not good, he could take more photos to solve it and increase the probability of taking a satisfactory photo. 4. ** To prevent the host from being overshadowed by the host ** - The accompanying objects in the scene (such as green plants, utility poles, etc.) could not be more eye-catching than the characters. Generally, the accompanying objects should not be larger than the main body, and the colors should not be brighter than the main body. Otherwise, it would distract the audience's attention on the characters. ** 3. Shooting Techniques (Shot Manipulation, etc.)** 1. ** Video Shooting (if involved)** - He could use a low-angle mirror lift (push forward), surround (take a picture of the scenery), and lower (finish). - There was also tension composition, upside-down horizontal shooting, graphic composition, telephoto shooting, leaf gap, backlighting shooting, ant perspective, leaf reflection, lock focus first, surround shooting, looking for light and shadow, side framing, road extension, overall finishing, and other techniques to create a cinematic feel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
documentary photography and commercial photography
There were many differences between documentary photography and commercial photography: - ** Purpose **: - The focus of documentary photography was to record stories and events with meaning and meaning. When combined with words, it could carry and record human society and civilization. Behind the photos were often thought-provoking stories, important events, or symbols of an era that inspired people's memories and thoughts. It had a wide spread value and archive value. Moreover, excellent documentary photography should be able to guide the viewer to think according to the "50,000 thinking mode". The photographer not only exposed the problem but also provided a solution. He even directly threw himself into activities that changed the reality of society. - Commercial photography conveyed the power and commercial value of a brand as quickly as possible. It was a visual form that served the business. Its main purpose was to promote products, services, or brand images. - ** Focus **: - The difficulty of documentary photography lay in the grasp of the story of the character. Although light, color, and composition were also required, the importance of the story was ranked first. It required the photographer to find interesting things in ordinary places, think quickly, and capture them quickly. It was necessary to objectively reflect the content or essence of the event as much as possible, with less subjective nature. If there was too much human intervention, the work would lose its authenticity, and it would not be a good documentary photography. - Commercial photography focused on the exquisiteness of the form and had high requirements for the visual effects of the picture, such as lighting and composition. It was to create an attractive visual image to serve the commercial goal. - ** Attributes **: - It was a unique art form of photography that could not be replaced by other art forms. - Commercial photography was essentially no different from other forms of visual services for business. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Ming photography studio photography
Studio photography had its own characteristics, the situation it faced, and the differences between it and other types of photography. From the perspective of working conditions, the work flow of the photographer in the studio was relatively fixed. Every day, after punching in for work, he would carry out his work according to the shooting schedule. Now, they usually served one pair of newlyweds a day. In the past, they might have to serve two pairs of newlyweds a day, so the workload was quite heavy. Because the studio was profitable, under long-term busy work, photographers were prone to fatigue and had little energy to create new creations. Most of the time, it was just to complete the task. As long as the customer did not have any major doubts, the job was completed. In terms of shooting style, the studio photography was themed. The costumes, props, and scenes were mostly fixed, and the main change was the subject. This caused the photographer to work mechanically to a certain extent. However, when he met a customer who inspired him, he could also take high-quality photos. The filming process of the studio was very standardized. From the pre-filming communication, makeup, clothing selection, to the posture guidance, lighting adjustment, and post-editing, there was a set of standardized processes. Although this could ensure that the studio rarely made mistakes and quickly took high-quality photos to meet the needs of different customers (such as wedding photography, parent-child photos, pregnant women photos, etc.), and could invest a lot of effort in post-editing to make the customers present the "perfect" effect, there were also drawbacks. This standardized process limited the photographer's creative space. The photos taken were easy to be the same and lacked variation. Moreover, the "excessive beautification" of the post-editing photos would also be considered "artificial" and "distorted" by photographers who pursued "original taste". Compared to those who played photography, studio photography focused on commercial results, satisfying the actual needs of customers, and pursuing efficiency. On the other hand, people who played photography paid more attention to the art of photography and pursued the presentation of personal ideas behind the photos. Therefore, in terms of creative freedom, studio photography was more restricted. However, there were also some studios that focused on technology and innovation, using digital retouching, virtual scenes, 3D printing, and other technologies. There were some difficulties for beginners who wanted to learn photography in a photo studio. A good studio usually wouldn't hire a novice photographer, while an ordinary studio might hire a novice as a handyman. The studio might not allow newcomers to touch the equipment for fear of damage. Moreover, the masters of the studio were often busy with their own work and did not have time to teach newcomers. They could learn the process in the studio, but it was difficult to accumulate contacts. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Artificial intelligence photography and ordinary photography
There were many differences between artificial intelligence photography (AI photography) and ordinary photography: 1. ** Principle **: - Ordinary photography was based on the basic optical and mechanical principles of the camera. Images were captured according to predetermined fixed parameters (such as shutter speed, aperture, and so on) or manually set by the user. - AI photography was based on big data and deep learning technology. When shooting, the camera would analyze the object in the viewfinder and automatically set the shooting mode and parameters according to the characteristics of the object. 2. ** Photographic effects **: - The effect of ordinary photos depended on the quality of the camera's hardware and the user's photography knowledge and operating skills. If the user lacked professional photography knowledge, it might be difficult to shoot the desired effect. - AI photography could allow users without professional photography knowledge to easily take good photos. The camera algorithm could quickly identify the gender, skin color, skin texture, and lighting of the shooting scene, and quickly match the beauty scheme, making women fairer and more natural, while men were more masculine and had a more defined outline. Moreover, the color of the AI photo was more accurate and better than ordinary shooting. 3. ** Photo-taking mode **: - To achieve better results in ordinary photography, the user might need to manually adjust the white balance, shutter time, USB, exposure compensation, filter, and other complex operations. The operation was relatively difficult and required more photography knowledge. - The AI camera mode was easy to operate. After the camera entered the light, it performed artificial intelligence analysis and calculation on the light scene of the subject, and then automatically matched the photo mode. When the user took a photo, the phone could determine the current environment and the type of object to be photographed, and it could match the best solution, eliminating the complicated manual adjustment process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Taobao clothing photography photography skills
Taobao clothing photography has the following photography skills: ** 1. Model and Scenery ** 1. ** Model Selection ** - There was no need for big models or celebrities. A model with affinity and a fashionable aura was enough. A new model or a young model could also be competent. Even a beautiful shop owner could personally try on the dress to attract customer traffic. 2. ** Scene selection ** - It was common to see half or full-body photos with partial indoor environments or street scenes. There were fewer samples of blockbusters or runway shows. ** 2. Shooting operations ** 1. ** Light-related ** - The lighting should be mainly soft or neutral light. Soft light box, soft light paper + cover can be used. - Shooting at a low light level can highlight the three-dimensional effect of the clothing; shooting at a high light level should be soft and uniform; fill light should prioritize the reflective board, followed by soft light. - When taking photos of light-colored babies, you should pay attention to the possible differences between the camera and the computer display. You can take a few photos first and try the effect with point focus. When taking photos of dark-colored babies (especially black), avoid using spot photography to prevent color distortion. It is better to use smart photography. - In terms of light intensity adjustment, attention should be paid to avoid "underexposed" and "overexposed" situations. It could be adjusted by correcting the exposure, contrast, curve effect, etc. of the light. 2. ** Cameras and shooting efficiency ** - The camera position had to be fixed. If necessary, they could shoot online to check the shooting effect in real time. 3. ** Method of composition ** - For the entire set of clothing, the center symmetrical shooting method was used; the close-up details could be shot diagonally, and there should be room for cutting when shooting to meet the requirements of the e-commerce 1:1 ratio. 4. ** Different shooting styles and angles ** - It could be shot from a super wide-angle lens and overlooking angle to make the clothing style fashionable and novel. It could also adopt a non-mainstream photography style that was popular among young people. At the same time, reasonable page design, classification, and other online store design were also very important. - Some shops used unconventional photography styles, such as super wide-angle lenses, overlooking angles, and unique web design (links, categories, shooting environment selection, and overall color tone processing) to stand out. 5. ** Walking pose shooting (if it involves dynamic display)** - For dynamic shooting, the best way to solve the problem of incoherent eyes was to plan the route of the eyes. For example, when walking, look at the camera first, look to the right, then look down, then look to the left, and then look at the camera. - When taking selfies in front of the mirror, the techniques of posing the whole body and half body included placing the top of the phone on the forehead, finding the center of gravity of the legs (the feet were 1.5 centimeters away from the bottom frame), adjusting the distance between the phone and the right leg. When the center of gravity was on the right leg, there could be a variety of postures, such as upside down, upside down, upside down. ** 3. Post-processing ** 1. ** Picture size adjustment ** - Generally, the size of the picture taken is about 2M-4M (the camera may be larger). The width and height of the picture can be adjusted to the appropriate size according to the needs. 2. ** Picture shape correction ** - If there are missing edges or distorted images during the shooting (such as this situation may occur when shooting food, clothing shooting can also be used as a reference), it needs to be corrected. 3. ** Flaw Repair ** - Dirt spots, fingerprints, scratches, and other flaws that appeared during filming, as well as the lens that was worn out, had to be cleaned up with a stain removal tool. 4. ** Changing the background color ** - The background of e-commerce photography photos is generally required to be white (the same is true for photos taken by Taobao and Lynx stores). You can use the Magic Wand or Pen Tool to replace the white background. 5. ** Increases liveliness ** - Often use small props to increase the freshness of the baby, and make good use of macro to reflect the details of the clothes, so that the buyer can see clearly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
