lens flare photography
The lens halo was a common phenomenon in photography. It was caused by the lens group consisting of multiple lenses. Although the lens had high penetration, there was reflection and scattering. The light rays that did not maintain the same direction as the incident light formed a halo, and the internal reflection and scattering of the lens were the main reasons. ** 1. The factors that affect the formation of lens halos ** 1. ** Shot structure ** - The more complicated the lens structure, the more halos appeared in the image. 2. ** Focus ** - Wide-angle lenses could deal with halos better because a short focal length would make the light source look small. Telephoto lenses performed poorly and needed to be equipped with a longer hood because telephoto lenses would magnify the picture elements. 3. ** Film coating ** - Different brands of lens coating technology were different, such as Canon's NAC coating, Nikon's NCC coating, Fuji's SuperEBG coating, Zeiss 'T* coating, Pentax's Smc coating technology, etc. Multi-layer coating lens components had a greater impact on the lens halo. 4. ** Color filter quality ** - Poor quality filter would cause more light spots and ghosting in the image, which would affect the lens flare. 5. ** Dust on the lens ** - Dust inside the lens would cause more lens halos, and all lenses would accumulate dust. ** 2. Ways to avoid lens flare ** 1. ** Use the hood ** - Most lenses would be equipped with a hood, which could prevent light from shining directly on the front mirror of the lens, effectively avoiding glare, and also protect the lens in the event of a slight impact. Petal shaped lens hoods usually had a better effect than non-petal (round) lens hoods because the petal hood took into account the aspect ratio of the camera film or digital sensor. 2. ** Cover ** - When shooting, use leaves, buildings, or body parts of the character (such as the head, shoulders, etc.) to block some direct light. You can also put your hand on the lens to block the sunlight (the hand forms a "C" shape and adjust the angle until the halo disappears, but be careful not to block the lens). 3. ** Use a fixed-focus lens instead of a zoom lens ** - The structure of a fixed-focus lens was simpler than a zoom lens. There were fewer optical components and less lens halos in the image. The structure of the zoom lens was complicated. The hood could not block all stray light at all focal lengths. There were more reflective inner surfaces inside, which made it easier for the lens to glow. 4. ** Changing the angle of the camera ** - Changing the shooting angle could change the position of the light source in the lens to prevent direct sunlight from entering the lens and eliminate the lens halo. It could also be recomposed to block the light source from the elements in the picture. If the halo was strong when it was backlit, the halo would be weaker when it was changed to side backlit. ** 3. Techniques of Using the Halo of the Shot ** 1. ** Change the angle of the sun to shoot ** - When taking photos with a lens halo, you can move the shooting position left and right to block the light from the target or part of the object. If the sun was behind the subject, the subject would be more attractive under the glow of the lens. 2. ** Shooting with a zoom lens and hood removed ** - To highlight the lens halo effect, you can use a zoom lens and a wide-angle lens instead of a fixed-focus lens. 3. ** Confirm and plan the position of the lens flare in the image ** - Because the lens halo might make the photo beautiful in some corners of the picture, but not necessarily in other positions, it was necessary to outline the shooting angle and the angle of the light to take an interesting photo. 4. ** Create the required light source ** - If you can't find an ideal light source, you can create it with photography methods, such as lamps, light bulbs, studio lights, or flashes. 5. ** Find the right time to shoot ** - Light at different times had different characteristics. The light in the morning was softer. Understanding the characteristics of natural light could make interesting photos. Light at different times could bring different emotions to the image. 6. ** Backlight Shooting ** - In order to have a lens halo, the image was shot using backlighting photography, such as backlighting to create an edge light or silhouette image. 7. ** Try to move the corner to adjust the light reflection ** - Moving the corner to adjust the amount of light reflection can get the reflected light that is suitable for the image content, such as water reflection or light passing through the bridge hole. Backlight photography may require manual focus because the camera will capture areas with darker light sources. 8. ** Try different apertures ** - When adjusting the aperture, the reflected light will produce different effects. Try different apertures to get the desired effect. Read more exciting novels for free
Inverse proportional function, the two quantities are reciprocals of each other
For the inverse proportional function,<y =<frac>{k>{x>}>(<k> is a constant,<k> 0>),<x> and <y> are not necessarily the reciprocals of each other. In the inverse proportional function,<xy>= k>. When k = 1, x and y are reciprocals of each other; when k = 1, x and y are not reciprocals of each other. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The most authoritative way to collect cultural relics and works of art
The collection methods of cultural relics and artworks varied according to the length of time they were stored. In terms of long-term storage, it was ideal to store it in professional places such as museum, art gallery, and art center. The storehouses in these places were generally more complete in design, and the cultural relics would not be moved around casually. However, most private collections were usually stored in non-professional places such as homes, general warehouses, or ordinary display spaces. The environment was crucial when it came to collecting cultural relics and artworks in these places. Cultural relics were easily affected by the environment. If they were too wet, they would mold. If they were too dry, they would crack. If they were too hot or too cold, they might even deteriorate. Therefore, they had to try their best to create a stable temperature and humidity and suitable lighting conditions, and there must be certain safety measures. In terms of short-term storage, it included the means of transportation of cultural relics and short-term exhibition venues. In this case, the most important thing to be wary of was the occurrence of unexpected situations, such as accidents during transportation, rapid changes in temperature and humidity, human errors (such as drinks overturning), etc. This required the transportation and exhibition units to do a good job in protecting them. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
