Light photography homework
The following is an example of a light photography assignment: * * I. The basic characteristics of light and its application in photography ** 1. [Strength] - The intensity of the light was directly proportional to the intensity of the light source and was inverse to the square of the distance between the subject and the light source. For example, when taking a portrait outdoors, if it was sunny at noon, the light source (sun) was strong, and the light on the subject's face was too strong, it might cause overexposed or hard shadows. At this time, you can control the exposure by adjusting the camera parameters (such as reducing the aperture or lowering the IQ), or use the shade tools (such as hoods, parasols, etc.) to reduce the light intensity. On the contrary, on cloudy days or in a dark indoor environment, the light intensity is weak. You may need to increase the aperture, increase the IQ, or use auxiliary lighting equipment (such as flash, soft light, etc.) to ensure adequate exposure. 2. * * Direction ** - * * Straight Light **: The shooting direction is the same as the direction of the light. It was suitable for shooting blue sky and other objects that wanted to highlight color. It could make the blue sky bluer and the landscape more saturated. For example, when shooting a large sea of flowers in the landscape, the light could make the colors of the flowers appear bright and full. - * * Side Light and Side Light **: The photos taken with these two kinds of light are rich in color and have a strong three-dimensional effect. When taking portraits, side-lighting or side-lighting could create a three-dimensional sense of the face, making the facial features look more three-dimensional and deep. For example, when taking a portrait of an old man, the side light could highlight the wrinkles on his face and increase the storytelling of the picture. - * * Side Backlight and Backlight **: Side Backlight and Backlight are mainly used for shooting sunrise and sunset scenes. Backlight can also be used to shoot silhouettes. For example, when shooting a sunset at the beach, using backlighting could capture the sun's flares and the sparkling sea surface. At the same time, people or objects could form black silhouettes to create an artistic sense. 3. * * Color temperature ** - Different color temperatures would give different tones to the photos. For example, light with a low color temperature (such as early morning or evening sunlight) would make the picture appear warm and soft, while light with a high color temperature (such as cloudy or fluorescent light) would make the picture appear cool and quiet. When shooting food, the warm light with a low color temperature could make the food look more attractive and increase appetite. * * 2. The use of light in different environments ** 1. * * Exterior environment ** - * * Daytime ** - * * Morning and Afternoon **: The lighting is relatively soft, suitable for a variety of shooting topics. You can use side light or side backlighting to shoot people, buildings, etc. to get a better three-dimensional sense and texture. For example, in the shooting of ancient buildings, side lighting could create a contrast between the walls and decorative lines of the building, emphasizing the characteristics of the building. - * * Noon **: The sun is shining directly, and the light is strong and hard. It is easy to produce strong shadows. If you want to shoot at noon, you can use a reflective board to fill in the shadow, or find a place with shelter (such as under the shadow of a tree or building) to shoot. For example, in street photography, using the shadows of buildings as the background could prevent the background from being too bright and affect the performance of the subject. - * * Sunset (prime time)**: The light is soft and the color temperature is low. It's the best time to take pictures of landscapes and portraits. They could use backlighting to shoot people, creating beautiful silhouettes, or using warm light to shoot scenery, creating a romantic atmosphere. For example, when shooting the mountains and clouds at sunset on the top of the mountain, the warm light would make the whole picture look like a fairyland. - Blues Moment (After Sunset): The sky appears blue. At this time, the beginning of the night scene can be taken. You can combine the sky and the city lights to take a unique night scene photo. For example, when shooting high-rise buildings in the city, the blue color of the sky and the lights of the buildings complemented each other to increase the layering of the picture. - * * Night ** - When shooting at night, there was less light and they mainly relied on artificial light sources. Such as street lamps, neon lights, etc. Long exposure could be used to capture the trajectory of light, such as the trajectory of the headlights of cars on the road, creating a flowing line. At the same time, you can also use a hand-held flash or an external flash to fill in the light for the main body. For example, when shooting street performers, the flash can highlight the artist's expression and movements. 2. * * indoor environment ** - If there were windows in the room, they could use the natural light that came in through the windows to shoot. Side lighting or backlighting could create interesting lighting effects. For example, the green plants in the studio could be made translucent by backlighting, which increased the beauty of the picture. If there is insufficient light in the room, you can use auxiliary lighting equipment such as table lamps and photography lights. When taking indoor portraits, pay attention to the angle and intensity of the light to avoid strong shadows or overexposed. * * 3. Analysis of the use of light ** 1. Take a portrait as an example - If you want to take a fresh and bright portrait photo, you can choose the fairing. At the same time, you can choose a simple and bright scene on the background, such as a white wall or blue sky and white clouds. However, this might lack the three-dimensional effect, so you could add some background elements or adjust the posture of the character to increase the layering of the picture. - If you want to pursue artistic and three-dimensional sense, you can use side backlighting or backlighting. When shooting against the light, you need to fill in the light on the person's face. You can use a reflective plate or a flash. For example, when taking a portrait by the sea against the light, the edges of the character's hair would have a golden outline light. The face could also be clearly shown after the light was added. The background was the sparkling sea, and the picture effect was very beautiful. 2. Take shooting scenery as an example - When shooting mountain scenery, the side light could highlight the ups and downs of the mountains. For example, in the morning or evening, the side light would create a strong contrast between the sun and the dark side of the mountain, enhancing the visual impact of the picture. - When shooting the forest, the backlighting could make the leaves appear bright, and at the same time, it could form a beam effect (Tyndall effect) in the picture to increase the mystery of the picture. This effect could be highlighted by adjusting the shooting angle and exposure parameters. Read more exciting novels for free
History of photography homework
The following is an assignment on the history of photography: ** I. The Origin and Early Development of photography ** 1. ** The exploration of early optical principles ** - The China were the first to discover the concept of a basic pinhole camera. Around the 5th century B.C., there were records of pinhole imaging. The image was formed by flipping the "pinhole" on the opposite wall. A hundred years later, the Greek philosopher, aristotle, discussed the formation of the image of a small hole in his work. In the 10th century, the Arabian scholar Hasan Ben Hasan wrote a manuscript describing the working principle of the camera and the principle of simulated photography. The camera was a dark, enclosed box-shaped space with a hole on one side. Light passed through the hole to create an upside-down image on the meeting surface due to optical principles. It was the prototype of the modern camera. 2. ** Getting closer to photography ** - In the 15th century, the earliest prototype of the camera, the "camera obscura", appeared. Then, the pharmacists discovered the property of silver chloride-black when it was exposed to light, and made paper with silver salt, which laid the foundation for the birth of photography. 3. ** The first invention of photography ** - In 1822, Nieppes used a self-made camera and took ten hours to complete the first human photo,"The Items on the Table." In 1826, he took "The Scenery Outside the Window." Later, he worked with Daguerre to improve the technique, but after Nieppes died in 1833, Daguerre registered a patent in his own name in 1839 (Daguerre Law). Although strictly speaking, Nieppes was the pioneer of photography, Daguerfa's camera set was very popular at that time. However, due to the limitations of Daguerphine's own technical principles, photography was replaced by the Carlo Method, which was developed almost at the same time. - Around 1824, Nieppes also invented the first practical photography technique, which was to paint asphalt on a silver plate to obtain an image. This technique was widely used in portrait painting until the mid-1850s. In July 1839, the Frenchman, Hippolyte Bayard, discovered a method to obtain images directly on paper. A piece of paper covered with silver chloride-turned black under light, and after being sensitized by silver iodinate, it was exposed in a dark box for 30 minutes to 2 hours. At the same time, Henry Fox Talbot of the United Kingdom created the "salt paper" photography method. He soaked the writing paper in a diluted solution of common salt and coated it with light-sensitive silver chloride-to capture the image of the camera lens. In 1819, John Hershel discovered that soda could remove the fixing effect of unexposed silver salt. Daguerre and Talbot used soda as a fixer to perfect the photography invention, and Hershel created "photography". Negative and positive. ** 2. The Development and Spread of photography ** 1. ** The improvement and popularity of photography techniques ** - In the late 19th century, American entrepreneur George Eastman was crucial to the development of photography technology. In 1901, the Kobold Brownie was introduced. It was the first commercial camera on the market that could be used by the middle class. Although it only took black-and-white photos, it was popular because of its efficiency and ease of use. 2. ** The development of color photography ** - Color photography was widely explored in the 19th century, but it was not until the mid-20th century that it began to have commercial value. 3. ** The development of different types of cameras ** - Oscar Barnack was born in the second half of the 19th century. In 1912, he researched the design of a small camera using 35mm film. In 1913, he successfully manufactured a prototype 24× 36mm camera, becoming the ancestor of the 35mm camera. ** 3. The development of the status of photography ** 1. ** From technology to art ** - After photography was born, it was initially used purely as a mechanical tool. Later, it began to imitate the style of painting and became one of the branches of art. 2. ** Become an independent art discipline ** - After the first world war, photography began to explore its own body, producing its own ideas and methods, and officially became an independent art discipline. 3. ** The prosperity of photography ** - After the Second World War, the capital market prospered, camera technology improved, and photography ushered in a new era. ** IV. The application of photography in war and news reporting ** 1. ** Early War Photographic Report ** - In 1855, Roger Fendon reported on the war through photography for the first time. He took 350 photos of the German war. 2. ** The development of photography in the field of news ** - With the development of photography technology, the application of photography in news reports gradually increased, becoming an important means of recording wars and social events. ** 5. Other important events and people in the development of photography ** 1. ** Aerial photography appeared ** - In 1858, Gaspar Felix Tunecken (better known as Nada) completed his first aerial photography. 2. ** Special photography techniques and exploration ** - In 1860, Nada used a portable light source to photograph the catacombs in Paris, showing the exploration and application of photography in different scenes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

photography homework, single-lens reflex photography
Here are some tips on how to use DSLR cameras for photography homework: ** 1. The camera settings ** 1. ** Shooting Mode ** - Try to use manual mode. Manual mode allowed the photographer to precisely control the camera's parameters according to the specific shooting scene and needs, while automatic mode might not be able to meet some special shooting requirements. 2. ** White Balance Setting ** - If there was a color difference in the photo, it might be caused by the use of household light bulbs or the camera's default automatic white balance setting was inaccurate. In this case, you can try to set the white balance to daylight mode, or try to take a photo in all other white balance modes to compare which mode is closer to the actual color. 3. ** Setting of the sensitivity ** - For example, the higher the value, the brighter the photo, but at the same time, the more likely it was to have noise. It needed to be adjusted together with other values (such as aperture, shutter speed, etc.). For example, for a small object, you can set it to 200, and for a large object, you can set it to 400. 4. ** Exposing settings ** - The exposure value was displayed as-0.7,-0.3, 0, 0.3, 0.7, 1, etc. The higher the value, the brighter the photo. You can set the exposure value to 0.3 during the test shoot. 5. ** Shutter Speed Setting ** - Shutter speeds such as 1/60, 1/80, 1/100, 1/125, etc. The smaller the decimal value, the slower the speed, the more light entering the camera, and the brighter the photo taken. 6. ** Aperture setting ** - The smaller the aperture value, the larger the aperture. The more light entered, the brighter the photo. The larger the aperture value, the smaller the aperture. The less light entered, the darker the photo. It was important to note that the aperture and aperture value were in inverse proportion. The value on the camera was the aperture value, and the result after the adjustment was the aperture. For example, a photo taken with an aperture value of 3 is brighter than a photo taken with an aperture value of 6. ** 2. Shooting Techniques ** 1. ** Composing Skills ** - Diagonal composition, triangular composition, and other methods could be used to make the picture more beautiful and stable. He could also try the full-body composition method. - When shooting, you can stagger the composition or capture the moment when the character walks by to create a picture-in-picture effect. 2. ** Basic principles of filming ** - To make the photo have a clear and distinct theme, whether it was a person, a still life, or an event, it needed to be clearly expressed to avoid ambiguity or all-encompassing. - A good photo must draw attention to the subject so that the audience could immediately notice the core of the photographer's intention. - It made the photo more concise and removed those elements that couldn't set off the subject or even distract attention. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
