The concept of overexposed and under-exposed in DSLR photography
In single-lens reflex photography, overexposed meant that too much light hit the exposure medium (such as the image sensor or film), causing the scene to be brighter than in real life. The brightest part of the image might be blurred and the details lost due to overexposed. In extreme cases, the severely overexposed image would turn pure white, and too much light would destroy the details of the picture. Under-exposure refers to the lack of light in the image sensor to form details and dark tones. A scene with insufficient light has almost no details in the under-exposed photo, usually looking dead black. When there is too little light, the image will be blurred. However, under-exposed photos are sometimes difficult to identify because the bright parts are clearly discernible compared to the blurry dark parts. Read more exciting novels for free
overexposed photography
In photography, over-exposure refers to the situation where too much light hits the exposure medium (such as the negative film of a film camera or the image sensor of a digital camera) due to the aperture being too large and the shutter being too slow. When the image sensor (or film) receives too much light, the scene will be brighter than in real life. The brightest part of the image may become blurred due to overexposed, and the details will be lost. In extreme cases, the severely overexposed image may eventually turn pure white, thus destroying the details of the picture. In order to avoid partial overexposing, the following methods can be used in the early stages of shooting: 1. For example, adjust the light measurement mode and the position of the light measurement point. For example, adjust it to spot measurement, and measure the light in the area that is easy to be exposed, but this may make the whole photo darker. 2. When shooting, adjust the aperture and reduce the sensitivity (less than 100). 3. Increase the shutter speed (the higher the decimal, the faster the shutter speed). 4. When shooting, after the auto exposure, reduce the exposure by 1 - 2EV. 5. If the above methods fail to avoid partial overexposed, it may be that the shooting time is not suitable. It is recommended to avoid shooting at noon on sunny days. In terms of shooting scenes, if the shooting scene was dark, the exposure method of "better over than under"(exposure to the right) could be used. This method tended to be overexposed rather than under-exposed. Although it might cause the brighter parts of the scene to be overexposed, as long as the main exposure was normal, it was acceptable to overexpose the unimportant parts. Its purpose was to record more dark details for later adjustment. In addition, when the video was over-exposed and the parameters could not be changed (for example, the shutter speed could not be changed in order to capture the motion blur), the variable dimmer lens could be used to reduce the amount of light entering the camera to solve the over-exposure problem. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR photography is white
DSLR photography may be caused by the following reasons: 1. ** Over-exposure **: Over-exposure will cause things to lose a lot of details and become layered, causing the image to turn white. 2. ** Flash is too strong **: If you use a DSLR flash to shoot, the flash will be too strong, and the photo may appear white. 3. ** White balance setting problem **: The camera is not that smart. Different light may affect its judgment of white. For example, under dim indoor light or incandescent light, it may cause deviation in white and become white. 4. ** Inappropriate shooting mode **: If you use the scene shooting mode, but the actual shooting scene does not match the selected mode, it is easy to cause color reproduction problems, which may lead to white. 5. ** Mishandling color settings **: DSLR cameras are highly controllable. Mishandling color settings may cause unnecessary problems, including the image turning white. 6. ** Monitor effect **: If the shooting scene is bright and observed through the monitor, there may be problems with inaccurate exposure and color reproduction, which may cause the picture to turn white. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Simple DSLR photography tutorial
The following is a simple DSLR photography tutorial: ** I. The structure of a single-lens reflex camera ** 1. Understanding the body, lens, sensor, viewfinder, shutter, display, and other components were the basic components of an DSLR camera. ** 2. Shot parameters ** 1. ** Type of lens **: For example, Canon lenses include different types of lenses such as EP, ESF-S (AP-S format), MP-E (1x or higher), and TS-E (shift-axis lens). 2. ** focal length **: For example, the Canon EF24 - 105mm f/4LIS USM lens, 24 - 105mm means that the maximum wide-angle end is 24mm, and the maximum telephoto end is 105mm; if there is only one value, it is a fixed-focus lens. 3. ** Maximum Aperture **: f/4 represents the maximum aperture, only one value represents a constant aperture lens, and two values represent the maximum aperture of the wide-angle end and telephoto end respectively. For example, L represents a Canon professional lens (with a red circle in front of the lens), IS represents anti-shake function, USM represents an ultrasonic motor, and II represents the second generation of this lens. ** 3. Focus related knowledge ** 1. ** Introduction to focal length **: It refers to the distance between the center of the lens and the surface of the sensor. The unit is millimeters (mm). 2. ** Focus length, field of view and depth of field **: The shorter the focus, the larger the shooting range and the greater the depth of field; the longer the focus, the smaller the shooting range and the smaller the depth of field. 3. ** Focus length and x-ray effect **: The shorter the focus, the stronger the x-ray effect (greater distortion); the longer the focus, the weaker the x-ray effect (lesser distortion). ** 4. Movie Tune ** 1. ** Concept **: Shadow tone refers to the brightness of a photo. Bright photos are high-profile, dark photos are low-profile, and neither bright nor dark photos are mid-tone. 2. ** Different shades **: Bright objects are suitable for high-profile performance, while dark objects are suitable for low-profile performance. ** 5. Shooting Mode Setting (for beginner users)** 1. ** Automatic or P mode **: suitable for beginner users who have just come into contact with the DSLR camera and haven't learned it in depth. Basically, there are not many settings. Just press the shutter and you can shoot. 2. ** AR (Aperture priority mode)**: You can set the aperture value (F value) yourself. The smaller the F value, the larger the aperture, and the higher the degree of blurring outside the main body. It is suitable for shooting scenes such as portraits, food, and macro scenes that focus on blurring the background. The higher the F value, the smaller the aperture, and the better the layering of the scenery. 3. **TV (Shutter priority mode)**: Set the shutter value manually. The smaller the value, the longer the exposure time inside the camera. It is suitable for shooting moving objects in a dark indoor environment (a tripod is needed to prevent the image from blurring). The higher the value, the shorter the exposure time of the camera. It is suitable for shooting fast-moving objects to prevent the subject from blurring the photo due to high speed. 4. **M (Manual)**: You need to manually set the shutter, sensitivity, and aperture size. It's relatively difficult, but it's a necessary skill for professional photographers. For example, outdoor portrait: 1/100s, 100F1.2 - 2.8; indoor portrait: 1/80s, 1500F2.8 or below; baby/pet photography: 1/200 or above, 100 - 800F1.4 - 5.6; still life/gourmet photography: 1/80s- 1/200s, 100 - 400F1.2 - 4. ** 6. Shutter Usage (Focus)** When you press the shutter, press it slightly. When the small square in the lens appears in the position you want to shoot (indicating that the focus is successful), then press the shutter. This way, the photo won't be out of focus. If the DSLR is a touch screen, the position where the hand touches will be the focus. ** 7. Setting of light sensitivity (USB)** The higher the sensitivity, the brighter the photo, but the worse the quality, the more noise; the lower the sensitivity, the darker the photo, but the better the quality, the less noise. Generally, it was recommended not to exceed the range of 1600. If you were to shoot outdoors on a sunny day, you would only need to shoot around 100. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Will smartphone photography replace DSLR?
Smart phone photography had great advantages in some aspects, such as high cost-performance ratio, convenience, ease of operation, efficient post-processing, etc. Moreover, with the development of technology, its photography ability continued to improve, and it could meet the needs of many people in daily shooting scenes. However, DSLR cameras were irreplaceable. For example, they had higher professional performance in terms of image quality, color resolution, tolerance, depth of field control, angle of view and composition, light and texture, etc., especially for those who pursued high-quality photography, needed more powerful optical performance, had extreme requirements for image quality, and were used in professional photography. Therefore, it was unlikely that a smartphone could completely replace a DSLR camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
E-commerce photography, DSLR selection
For the choice of an e-commerce camera, the following aspects could be considered: 1. ** sensor size **: The sensor is the core component of the camera. The common specifications include full-frame (35mm), APS-C (about 23mm), miniature three-quarters (about 17mm), etc. E-commerce cameras may have a surplus of full-frame, and three-quarters of the miniature camera may not be enough. It is recommended to choose the APS-C format sensor, which can provide sufficient resolution and good image quality. 2. ** Pieces **: Pieces refer to the maximum photo size that the camera can output. The unit is a million pixels (MP). It was not that the higher the better, as it would increase the noise and storage space. For e-commerce shooting, it is recommended to choose at least 10 - 15MP or so, which can meet the requirements of image quality and size on most platforms and websites. 3. ** Video Function **: If you plan to use the camera to shoot videos, you need to consider its video function. Most DSLR cameras had high-definition video capture capabilities, but some cameras had better video capabilities. For high-quality videos, choose a camera that supports 4K resolution or high-speed photography. 4. ** Lenses compatibility **: Lenses compatibility is very important for DSLR cameras. The quality and performance of the lens will greatly affect the final photo. If you already have some lenses or plan to buy multiple lenses, be sure to choose a camera with good compatibility. 5. ** autofocus speed **: autofocus speed is very important when shooting moving objects. Some cameras have faster autofocus speed, which helps to capture more moments. 6. ** Weight and size **: If you need to carry a camera with you for shooting, it is more suitable to choose a lightweight camera. 7. ** Manipulation **: The camera with an intuitive operation interface can help the user master the usage method faster. 8. ** battery life **: If the shooting process requires continuous use for several hours, battery life is an important consideration. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Bachelor's Thesis on Concept photography
The following is an example of an undergraduate thesis framework on perceptual photography: ** Title: Concept photography: A new dimension of artistic expression and concept transmission ** ** abstract **: This thesis aims to explore the unique form of photography, the concept photography. Through the analysis of the origin, characteristics, creative techniques and its significance in the context of contemporary art, it reveals how the concept photography breaks through the limitations of traditional photography and becomes an important artistic means to express profound thoughts and concepts. ** I. Introduction ** (I) Research background With the continuous development of contemporary art, photography was no longer limited to purely recording functions. As a new form of photography, concept photography gradually attracted the attention of artists and scholars. (II) Research Purpose and Meaning This paper will discuss the nature, development process and value of the concept photography in contemporary culture, and provide theoretical support for further understanding of contemporary photography. ** 2. The Origin and Development of Concept photography ** (I) The Origin of Concept photography 1. The Rise of Western Concept of Photography Originating from the 1960s, it was a part of post-modern art, which artists used to reflect the contemporary psychological alienation, express their thoughts and critical emotions. 2. The sprout of China concept photography In the 1980s, artists began to intervene in the field of photography through performance art and installation art, showing the exploration and cross-border complexity of art. (II) The Development of Concept photography With the development of contemporary art, there were various branches of concept photography. Modern works were more experimental, and the concept of exploration was more abstract. The boundaries between them and other artistic media were gradually blurred. ** 3. The characteristics of concept photography ** (I) Concept as the core 1. The difference from traditional photography Traditional photography focused on recording the true emotions of the objective world, while concept photography used images to express the inner concept, which was the extension and evolution of concept art in the medium. 2. The transmission of ideas Through photography, he conveyed a certain concept, showing an in-depth analysis of the state of human existence, proposing meaningful topics of extension, and triggering in-depth thinking. (II) The Diverse Forms of Manifestation 1. Not limited by traditional photography techniques Unlike traditional photography, which was strictly restricted by factors such as the camera, lens, light and shadow, composition, and so on. For example, in Sugimoto Boshi's works, the photographic paper was just a canvas to him. His series of electric discharge field was created in the dark room by continuously releasing electricity on the negative film. His works were accidental. 2. Unique visual presentation It uses a unique perspective and image combination to show the analysis of meaningful topics, which can involve life attitudes, social phenomena, character stories, etc. ** 4. Creation Techniques of Concept Photographer ** (I) Selection of theme 1. Dig from society and life The creators chose topics from social phenomena and personal life experiences, such as photography that reflected the concept of environmental protection and paid attention to the problems of human living environment. 2. The materialization of abstract concepts He used abstract concepts such as time and memory to materialize through photography, just like Hiroshi Sugimoto, who integrated the philosophy of life, time and history into his creation. (2) Creation process 1. Longer concept brewing The conception of a concept usually required a long time to think. The photographer had to rely on the ability to observe the customs and observe the emotions to create. 2. Breaking the traditional rules of photography The creators broke through the technical and aesthetic rules of traditional photography and used innovative means to express their ideas, such as using mobile phones for concept photography, making use of the convenience of mobile phones and not being demanding by environmental factors. ** 5. The significance of concept photography in the context of contemporary art ** (I) Impact on contemporary cultural narrations It provided a new context for the narration of China contemporary culture and became an important way to express contemporary thoughts and emotions. (II) Guiding the audience's aesthetic and thinking 1. Challenging the audience's traditional aesthetic concept It broke the audience's aesthetic expectations of traditional photography and prompted the audience to re-examine the definition and boundaries of photography. 2. Arouse the audience to think deeply The concept conveyed by the work prompted the audience to think about the deep problems of human survival and social phenomena. ** 6. conclusion ** (I) Research summary Concept photography was a unique art form that was different from traditional photography. It took concept as its core and had various forms of expression and creative techniques. It was of great significance in the context of contemporary art. (II) Research prospects With the development of the times, concept photography would continue to evolve. In the future, it might be combined with more art forms and emerging technologies to further expand the boundaries of its artistic expression. When writing the thesis, he needed to further study the relevant artists and their works, quote specific examples for detailed analysis, and refer to more academic materials to ensure the depth and academic nature of the thesis. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
