There were many ways to control the background of a macro camera: - ** Use artificial background **: You can use colored or black cardboard. Black cardboard is more commonly used. If you want to shoot a more natural effect, you can choose pure green or mottled green cardboard, but avoid using reflective cardboard to avoid impact on the subject. - ** Illuminate the main body with a flash **: Use the flash as the main light source to illuminate the main body and blur the background. If the background was a solid color, the position of the flash was not critical. If a hand-drawn mottled background was used, it needed to be placed outside the focus of the camera to make the mottled pattern on the cardboard look softer and blurry. - ** Control the light with the flash **: Since the flash can completely control the light, the output power of each flash can be adjusted individually. If you want to highlight it on one side of the main body, you can increase the power of the flash on that side to freely set the light ratio. Use a flash on the right and left side of the main body. When the power is the same, the surrounding light effect can be shot. Increase the power of a flash and combine it with the aperture value to shoot the effect of a stronger light source in the left and right directions. - ** Control the background with a flash **: Add a third small flash close to the cardboard behind the subject. By moving the flash close to the cardboard, the background can be brightened or darkened. The same effect can also be achieved by turning on or off the power. In some cases, dimming the content behind the subject can make the subject more prominent. - ** Create a black background **: First, use a black cardboard; second, use two flashes. When the two flashes are turned on and the aperture of the camera is Ü/ 16 or Ü/ 22, even if there is a green cardboard behind the subject, it will turn black (the result of light decay). This technique can be used to shoot a black background in the wild at noon on a sunny day. With an aperture of Ü/ 8 or Ü/ 11, sunlight was enough to illuminate the background; if the aperture was completely reduced and the high-speed flash sync reached a shutter speed of 1/1,000 seconds, the background would be completely black. Sometimes using a black background can make the main body stand out. If there is a lack of separation between the flowers or if the flowers merge with the black background, you can use the third flash to backlight the main body, creating a halo or edge light to increase the drama. - ** Cloudy Day **: When shooting on a cloudy day, the background is dark. If you want to capture details, you can lower the shutter speed to let the surrounding light enter the camera sensor. Try to use slower and slower shutter speeds until you achieve the desired effect. In this case, you need to use a tripod, especially when the shutter speed is reduced to 1/30 of a second. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
You can take a look at the novel "Kong Fang's World" written by the author Song of Thorns. Although the ending is open, the whole story is quite exciting. The protagonist also has a world system. I hope you like this fairy's recommendation. Muah ~😗
Macro fiction can be defined as a form of storytelling that takes a wide-angle view, exploring extensive events and concepts. It might have multiple interwoven storylines and a focus on big-picture perspectives.
😋I recommend the following books to you: 1. [Qianqiu Offered]: It described the change in the female master's mentality from arrogance to strategy. It contained the elements of judging the situation and strategy. 2. "Zhenguan Meng Guogong": The female protagonist acted dumb and acted cute in front of the emperor, but she was able to make a living. She relied on her ability to judge the situation and observe people's expressions. 3. "Reborn Laughing and Fighting the Wealthy": In order to resist a loveless marriage, the female protagonist hid her identity and entered a Multinational Food Company. She relied on strategy and personal qualities to gain love and success. I hope you like this fairy's recommendation. Muah ~😗
The main features of the Macro Mecha in this story could be their large size. This would make them very imposing and powerful in combat.
If you want a fantasy novel set in a legendary world, I recommend Battle Through the Heavens. " Battle Through the Heavens " was an online fantasy novel created by Tian Can Tu Dou. It described the growth of a young man. He had experienced all kinds of challenges and battles in the process of pursuing strength, and finally became the powerful ruler of the Dou Qi continent. The plot of the novel was full of ups and downs, and the characters were vivid. It was a very popular fantasy novel.
Start by looking at the overall structure. Check if the plot flows smoothly and if the beginning, middle, and end are well-connected.
For a functional, the necessary condition for the curve connecting the points and the sum to be an extreme curve (namely, optimization) was called the Eulerian equation. It is a second-order differential equation that can be expressed in three forms: (20.2a),(20.2b), and (20.2c). Formula (20.2a) is the original form of the theorem, Formula (20.2b) uses the index to represent the partial derivative and lists the independent variable form, Formula (20.2c) is the form after using the chain rule to find the derivative of and omitting the independent variable. This equation was equivalent to the first-order necessary condition for static optimization. It was important in dynamic optimization problems such as the lifetime utility of a family. By analyzing the partial derivative of the function, the curve that made the functional reach the extreme value could be determined. The Extraordinary Ordinary Life novel is equally exciting.

The book,"Microscope photography and business cases," used examples as the main thread to share the professional photography techniques of macro photography with readers and answer common questions for beginners. For example, in macro photography, there were many techniques for shooting common subjects such as insects. If the timing was good, such as in the morning, evening, after the rain, cold weather, when insects were eating or mating, they were relatively quiet and easy to shoot. If the insects flew away, they could stay in place (because they had the habit of nostalgia like dragonflies) and wait for them to come back. They could also find insect breeders to obtain more filming opportunities. Under the premise of ensuring the safety of the insects, they could take temporary enforcement measures to calm down the disobedient insects, or they could create their own filming environment. In terms of equipment, he mentioned the shooting parameters of different equipment such as the D700 with the Tenglong 90mm macro lens and the Nikon 105VR macro lens, such as aperture, exposure time, and so on. In terms of mobile macro photography, the entry-level players had to understand the macro function skills of the mobile phone, choose the right subject, maintain stability, and use natural light. In order to advance, they had to learn to use an external macro lens, manually focus, adjust exposure, use background blurring, etc. There were also examples and parameters for different scenes. These were all knowledge that macro photography could apply to business cases or daily photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The background information regarding the recommendation of the fantasy novel was not clear. The search results mentioned the background of some fantasy novels, such as the outer space universe, ancient families, and other worlds, but did not specifically recommend which fantasy novels had a strong background. Therefore, it was impossible to provide any background information regarding the recommendation of the fantasy novel.
