The application of color filter in photography
In photography, color filter was widely used: 1. ** In terms of black and white photography ** - It is used to correct the color sensitivity of black-and-white films. - To adjust the contrast, for example, through the effect of a filter, the contrast between different tones in the picture would be changed to achieve the desired visual effect. - Eliminate the interference light and reduce the stray light that might affect the image quality. 2. ** Color photography ** - Correct the color temperature of the light source to ensure that under different lighting conditions, such as lighting with different color temperatures or natural light, the color can be accurately restored or achieve the color effect that the photographer wants. - Compensate the color. When the color in the picture is deviated due to various reasons (such as the influence of the environmental color, the characteristics of the film or the sensor itself, etc.), the filter can adjust the color. 3. ** Special Effects ** - The use of special shapes, structures, and optical properties of the filter can make the photos have special effects. For example: - The UV-filter (Ultraviolet Mirror) was made of colorless and transparent optical glass containing lead (which could absorb short light waves). It could absorb the ultra-violet light and eliminate the effects of fog. It was usually installed on the lens to protect the lens without exposure correction. - The Skylight Mirror (Skylight filter) is a light pink color that can absorb a little blue and violet light. It is used to eliminate the light blue hue on color films in cloudy or cloudy places. - The colored filter could filter out a portion of the light in the spectrum, allowing only a certain amount of light to pass through. Different colored filter colors had different effects. For example: - The Y-colored filter absorbed the violet and blue-violet light, giving the correct contrast between the day and the white clouds. - O orange filter can make red and yellow stand out, green and blue darker, suitable for mountain areas, seaside and other occasions. - The G green filter brightened the green leaves in the sun, making it suitable for taking close-ups of flowers in the park and people in the soft sunlight. - The R red filter lightens the red color and darkens the other colors. It can be used to create the effect of the moon in the morning light or infrared photography. - Close-up lens (half-length lens) was a concave lens with a long focal length. It was installed at the front of the camera lens to shorten the focal length of the lens. It was used to shoot small objects at close range and copy documents. When used, it needed to increase the exposure time by about a quarter. - The Reiden 80 color filter was blue in appearance. When using daylight color film to shoot under an iodine-tungsten lamp (the color temperature of the light source was lower than the equilibrium color temperature of the film, and the color tone of the photo would be particularly red), the color filter could increase the color temperature of the light source, and the color reproduction would be normal, but it needed to compensate for the level 1 and level 2 exposure. - A soft light mirror (diffusing filter) uses the diffusing effect of light to make the originally bright and clear scenery become hazy and blurry, achieving a hazy and beautiful mood. For example, when shooting a girl or an old man, it can create a different atmosphere. - Starlight mirrors (such as cross-shaped mirrors and rice-shaped mirrors) can reflect point light sources and mirrors to form 4, 6, or 8-star starlight effects in photos. The intersecting lines in the mirror can be used to diffuse light. When shooting water or strong light sources (such as night street lamps, car lights, stage lights, etc.), it can produce starlight effects. - Rainbow lens (light filter) can produce a radiant and colorful effect when shooting scenes under strong sunlight, night lights, and stage flashes. - Hollow lenses (halo lenses) used a small hole in the middle of the close-up lens to make certain parts of the scene clear and bright. The surrounding was a virtual surface. Rainbow Starlight Mirror, Soft Focus Mirror, Soft Net Mirror, Spider Web Mirror, and Magic Mirror could highlight this effect. - The multi-prism (multi-image filter) grinded into a number of small planes on the mirror surface, causing the photo to produce multiple identical images, forming a patterned picture. The multi-image lens could be roughly divided into four types. One of them was a flat transparent part in the middle, and the surrounding was grinded into a number of small planes. The center of the photo was a clear image, and there were several images with slightly lower clarity around it. Read more exciting novels for free

However, the following types of drugs may have an improvement effect on the pores caused by excessive sebum secretion: 1. Retinoid acid drugs, such as retinoic acid cream, Adapalene gel, etc., could regulate the differentiation of the skin's corneoid cells, reduce sebum secretion, and thus improve the thickness of pores. 2. Anti-androgens: Spironolactone can suppress the secretion of sebaceous glands and improve the thickness of pores, but it needs to be used under the guidance of professionals. 3. [Vitamin medicine: For example, vitamin B6, which can effectively regulate the secretion of sebaceous glands on the face, improve pore blockage, and relieve rough pores.] 4. Others: Topical application of levocarnitine, 2% niacinamid, Salicolic acid, azelic acid and other drugs can also play a certain sebum suppression effect and alleviate the problem of large pores.

Is the reaction of the hydrogen carbonate-soda mixture 5:7?
In the reaction of <NH4HCO3>> and <<NaOx>>, the reaction would be different depending on the amount of NaOx. When there is a small amount of <Na (Ox)>, the chemical equation is <NH4HCO3 + Na (Ox)= NH3·H2O + NaHCO3>; When there is an excess of <Na (Ox)>, the chemical equation is <NH4HCO3 + 2Na (Ox)= Na2CO3 + NH3·H2O + H2O>. From the perspective of the mole ratio, there was no common case of the reaction of the mole ratio of <5:<7>. Usually, the reaction was discussed according to the ratio of 1:1 (small amount of NaOH) or 1:2 (excessive amount of NaOH). Therefore, the reaction between hydrogen hydrogen and hydrogen would usually not be 5:7. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Voyager King Dream Pointer mobile game strategy
The following is the strategy for the Dream Pointer mobile game: 1. ** Lineup Match **: - The team was made up of four main players and one substitute character. The substitute character unlocked its functions at level 18. Before that, it was basically a four-man battle. Newbies could consider using Krogdal (Old Sand) as the core to build a lineup. Old Sand was recognized as suitable for newcomers to explore during the closed beta. His damage output was strong and comprehensive. He had single-target explosion, group damage, damage addition, dispelling the enemy's buff, and other abilities. It could be paired with the top 4-star output Yamatsu. Yamatsu had both AOE damage and single-target damage, and could be combined with female characters. His talent and ability to suck blood made his survivability strong. In addition, with Nami, after confirming these three characters, he still needed 1 output crutch, 1 healer, and 1 dark need to fill in the positions (priority was given to female characters to maximize Yamatsu's ability). In the later stages, these support characters could be replaced with stronger characters, such as the strongest healer and support princess. - There were also some recommended lineups, such as Luffy + Brook + Shenping + Robin + Sauron (Great Airline); Usopp + Luo + Becky + Ace + Sabot (Luxi); Yellow Ape + Ace (Soul)+ Sanji + Ace + Hancock; Aokiji + Battle Peach Pill + Yellow Ape + Sengoku + Magellan; Hawkeye + Shanks + Netherworld Princess + Choba + Aokiji.

After drawing a partner, the skill will be automatically obtained. You can also use the blue card coupon to draw a skill. It is recommended to accumulate card items for ten consecutive draws to increase the chances of obtaining a four-star character. The character quality is, from high to low, five-star colored, four-star gold, crimson, sapphire blue, brilliant yellow, dark purple, and random. It takes about 79 draws to obtain a five-star character. 4. ** Instance Dungeon Challenge **: - It was recommended to prioritize farming gold dungeons because they were short of money in the early stages.
