The key elements of portrait photography

People should choose what kind of photographic lens?

A variety of camera lenses, although the figures can be used for photography, but, strictly speaking, people should have the following lens photography some of selectivity:

1, imaging

People photography lens image quality, it is necessary to end like the clear, but also have some soft effect. Because people are generally the performance of face-based photography, the camera image quality should be able to achieve levels of rich, realistic texture, detail absolutely shattered, skin moisture requirements.

2, the focal length

Generally equipped with a standard KODAK EasyShare M753 battery lens on both cameras, the war film camera focal length of the frame similar to the length of the diagonal. This lens, it should only take pictures of people the whole body or large bust. If the half-length figure or head for shooting close-up as too close, image perspective distortion is often caused by people, and some shots if the provisions in the near distance of the most recent photo shoot, can not be clustered into clear focus. So, head shot or close-up characters, then use the focus or telephoto lens, its focal length lens usually takes 1-2 times over the standard to 135 cameras, for example, the lens focal length to be as high as in the 105 meters, so that the camera and People distance, more than 1.5 meters can be maintained, both to make the focus clear, but also to avoid a big nose and ears and small deformation. Small photos of the indoor shooting, if you encounter the lack of deterioration of the situation, we need to use short focal length lens (ie wide-angle lens), but prone to near the far smaller and slightly deformed characters on both sides of the defect.

3, diameter

Half-length figures and head close-up shooting, to a large effective aperture of the lens is appropriate to make the subject clear and the background slightly blurred, and enhance a sense of near and far space perspective, thus highlighting the subject. In addition, the effective lens aperture large, slightly darker in the light of the circumstances but no flash, shooting people, still use a faster shutter speed.

Fifth, tourism pictures of people, what photographic equipment and accessories to bring?

1, photographic equipment

Travel pictures of people want to carry photographic equipment, generally light and appropriate. Typically, the film tour commemorative photo, holding an ordinary camera, a small 135 or "fool" the camera, can be applied. If the person preparing to further engage in photography, such as shooting some of the local customs, etc., it is best to carry a 135 interchangeable lens single-lens reflex camera, and coupled with a 28-80 mm zoom lens, both for photography needs to adapt to , but also reduce the equipment volume; Alternatively, you can use the camera, while the original standard lens, and then configure the 24-28 mm lens and 85-105 mm wide-angle lens, one each in order to choose. If you need the same time people of color and black and white photography, it is best to have two aircraft, each equipped with color and black and white film, alternating (if carrying the adjustable back 120 single-lens reflex camera, you only need one can be applied.)

2, annex

No matter what portable camera, lens hood and II are advised to keep a yellow filter. If conditions permit, it is best used to bring color and black and white photography of various main filter (including the UV mirror, sky mirror, polarizer, etc.) as well as black and white photography of yellow, red and green filters. Also carrying a small electronic flash or self-reflective panels for auxiliary lighting. To be able to maintain the camera and lens clean, to bring the lens paper and lens brush, if even with a good blow up balloons. Travel pictures of people, due to the hand-held shooting angle can be more free to choose, so a tripod with a low frequency, do not have to carry; but if can take to prepare for contingencies, and of course better. In addition, should made available for a pocket notebook, a brief record of shooting situations, including the date, weather, time, situation, characters and the use of aperture, HP pavilion zv5000 battery, shutter speed, etc., in order to accumulate the data, at any time refer to continually improve their standards.

What additional black and white figure photography often mirror?

Black and white figure photography, the camera lens before the commonly used additional mirrors, including the nature of change and change shade shadow imaging Results of two series. Example of the former variety of colored filters, air filters, UV microscopy and sky mirror and so on, which for example, soft mirror, halo of the lens and close-up lens, etc., are as follows:

(A), commonly used to change the nature of additional lens shade

1, a variety of colored filters

Such filter is optical glass with color and refined, yellow, green, red, orange, blue and other, were named in various colors. Its role is to prevent or reduce unwanted shade, relative to the required increase in the amount of light shade of the pass, to change the color and feel Gan Guangpian. Black and white figure photography, yellow filter is most commonly used, for example, in the case of blue sky, shooting outdoors people, once plus, you can absorb some blue light, making it less sensitive blue film, which appears in the photo the sky darker, and the effect of clouds was outstanding; otherwise, will be mixed to the same color blue and white. Into the white sky, dull. Yellow filters can enhance the level of character texture and delicate vivid color performance. It also has a transmission range, the characteristics of low light resistance, therefore, added with yellow filter, only half of file to open the aperture, while the addition of the yellow filter, but also just opened freshman profile aperture.

2, sky filter

This is half of the pale yellow or light gray, colorless translucent add a mirror. As part of its edges colored by the deep to shallow, gradually over to the colorless, transparent, therefore, also known as the gradient filter. Its role is to adjust the contrast between sky and ground. Specifically, the colored part of the purple blue of the sky can absorb or reduce the intensity of light the sky, the sky part of the limited amount of exposure in the film, so that the ground segment in the film more exposure. Use, the colored part should be facing up, no additional exposure. When photographing people in backlight, plus air filter, the effect is even better.

3, UV and Skylight lens

Most are colorless UV microscope, there are slightly yellowish; sky mirror is close to colorless or slightly reddish. Their main function is absorption of ultraviolet radiation in the atmosphere. UV effects on alpine photography more serious, and often hinder the clarity of the image. UV plus or sky mirror mirror, you can eliminate the influence of UV on the Gan Guangpian to improve image clarity, especially for distant scenery is more effective. Since UV and Skylight lens is a colorless or near colorless, no need to increase exposure for photography under any circumstances and no side effects, therefore, often added wear on the lens to protect the lens.

(B), change the video used an additional lens imaging Results

1, soft mirror

Soft lens effect, is to be part of the light through the lens refraction, so the photographer can maintain a certain image clarity, while a softer tone contrasts but also natural. The construction of soft lens in various forms, usually in a transparent glass, have the density of different circular ripples, or is the use of nylon or other fibers are woven into the mesh, so as to achieve the purpose of refraction separate incident. Add to wear soft mirror, close-up photo shoot women and children, can be soft and pleasing effect of images.

2, the halo of the lens

Halo shape of the mirror structure, is to open a hole between the glass lens, was surrounded by sand-like. Hollow in between, COMPAQ Presario r3000 Battery plus worn on the front of the camera will not affect the main image is focused. When photographing people, will face arranged in a circular hole location, you can get the normal resolution, and face around the outside of the image, due to lens-like effect on the sand, then show the effect of hazy halo. Add pictures of people wearing a halo of lens to use single-lens reflex camera is appropriate, because the photographer by the camera viewfinder, direct observation of the situation to the image halo.

3, Close-up Lens

Half-length mirror, also known as close-up lens is a convex positive lens, plus wearing, you can shorten the lens focal length, but also to shorten the distance of a recent photograph, so that images of people to expand, take full advantage of Gan Guangpian area. When shooting, the general need to increase exposure, but to use a small aperture in order to increase the dark deep corners to prevent false negatives loose. Practice in photography, taking pictures of people close-up close-up lens is not appropriate, because the close proximity of photography, easy deformation defects. In addition to the commonly used additional mirrors, there are many shadow mirror, star mirror, mirror in the ash and other special effects add a mirror, by the addition of, the first two can be respectively different radial multi-light image and the effect of the latter which can help reduce the amount of light rays through the role.
