Black and white photography skills of SLR camera

What are the skills to take black and white photos with a SLR camera? The following is the relevant information I collected for your reference only!

Photography was born in the black and white world. Black-and-white photography is a kind of photography that uses black-and-white film to express the subject image. Black-and-white movies, through the wonderful combination of black, gray and white, present a thick and lasting graininess and charming light and shadow texture, which has profound and vivid visual charm and is a good way to express emotions and render the atmosphere.

Nowadays, with the development of digital technology, black-and-white photography is no longer just a matter of black-and-white film era. Digital cameras also have a black-and-white mode, and post-image processing software can also make it easy for you to get black-and-white photos. Although the black-and-white images in the film age and the digital age are all black-and-white, the texture of the picture, the presentation of light and shadow and the shooting equipment are different. But the charm of black and white photography will not change because of the evolution of cameras. Black and white photography tells us that photography records light and shadow, and its world is only black and gray, and it transcends black and gray.

First, the basic knowledge of black and white photography

Color photography can give the picture more vitality in color, while black-and-white photography must pay more attention to the skills of lighting, theme, texture, perspective and composition in order to make the work more tense.

1, about running out of light

light source

Objects in the universe are divided into luminous objects and non-luminous objects, and luminous objects are called "light sources". The sun, electric lights and burning candles are all light sources. It is important to understand the light source. Different light sources need different shooting methods and settings. Does the light come from natural light such as the sun, or artificial light flashes?

How much light?

You need enough light to capture the details. Black-and-white film can't use color difference to express details, only light. In black and white photos, the beautiful blue sky will also be gray.

Direction of light

Front light, back light, side light, etc. The direction of light is different, depending on the depth, three-dimensional sense and details of the photos you need. Smooth light is relatively dull, but also delicate; Backlight is attractive, but the details will be destroyed; The side light has a three-dimensional effect and a good texture.

Quality of light

First, consider the shadows and contrast you want. Direct light produces strong shadows, while soft light produces smoother tones. In order to form a sharp contrast between shadows and bright areas, direct light should be used. In order to obtain the gray tone transition, soft light is used.

Step 2: Simple composition

Light and shadow composition

Emphasizing the theme of black-and-white photography with light and shadow is not only a test of photographer's strength, but also the weakness of black-and-white photography. If there is enough light, the photo may be perfect. But the wrong light will lead to too dark imaging or shooting failure.

shape

Without the help of color, you need to consider how to describe the shape. Shapes can be represented by blocking light and dark areas in photos.

sense of reality

The texture of the object surface appears in the realistic photos, while the fuzzy and smooth details appear in the idealized photos.

line

Lines can be used to guide the audience's attention to a specific place, and can also be used to express movement and tension.

rhythm

Photos, like music, can have their own rhythm. Repeat. Lines and shapes can create patterns and add rhythm to photos.

corner

The most important thing to consider is the perspective. Before you lift the camera, you should know what you want to shoot and how to show it. At this time, you need to consider the shooting angle, whether it is overhead shooting, overhead shooting or flat shooting, in order to be more brilliant?

3. Prominent themes

Black-and-white photography can bring us into a monochrome world, in which no color exists any more, and objects only look bright and dark, black and gray. When watching a work, all the attention is occupied by the things or emotions to be expressed in the picture. Of course, black and white photos can also add a romantic and eternal mystery to the work. Compared with ordinary color photography, it presents a completely different viewing experience.

4. Unique atmosphere

Black and white movies have a unique artistic atmosphere. For example, the dark tone of the ghost can describe sadness or emptiness, while the smooth texture conveys the feeling of openness and freedom. Charming black and white movies always have a little affection.

Second, the topic of black and white photography skills

Nowadays, many digital cameras have black and white shooting modes, but the effect of these settings depends largely on the imaging of the camera. If the black-and-white mode of the camera can't produce a good image, you can still use some extra camera settings and then use photo editing software to convert it into a black-and-white image. Editing software can also help photographers to change the contrast and brightness of pictures and improve the quality of photos.

Because the digital tolerance is small, it can't show as many gray levels as black and white silver salt, but when taking digital black and white photos, photos with pure black, pure white and intermediate tones can still be taken, but there are not as many layers as silver salt, and the expressive force will be worse.

Below, briefly introduce some shooting skills of digital black and white photos, hoping to help you in your future shooting.

Understand the exposure characteristics of digital cameras before shooting. There is no color factor in black-and-white photography, which depends entirely on the change of brightness, so the composition of black, white and gray in a photo is essential. Therefore, when shooting black-and-white film, we should accurately understand the brightness composition and contrast factors on the screen, and determine the appropriate exposure combination according to the creative intention. In fact, in the natural environment, the ratio of the brightest and darkest brightness of most scenes is far more than level 5, so don't worry about this problem.

Don't let the background be close to the brightness or hue of the subject, which will make the subject stand out. We can choose the background on the backlight surface or use a large aperture telephoto lens or a macro lens to atomize the background, so as to achieve the purpose of highlighting the subject.

In black-and-white photography, we should pay special attention to some things that look very different in people's eyes, because these things may be difficult to distinguish in the black-and-white world, such as red flowers and green leaves, which form a sharp contrast in the color world, but are gray in black-and-white conditions, so we'd better use color filters when shooting.

When shooting a black-and-white backlit portrait, it is best to improve the brightness of the face to reduce the brightness difference of the whole picture, especially when shooting a portrait outdoors on a cloudy day, because the light is too flat, the photographed characters have no three-dimensional sense, and even all of them are gray. At this time, we can use flash or external light to improve the brightness of the characters, thus highlighting the main body.

When taking digital black and white photos, the function of spot metering is also very useful. When using spot metering, we should pay attention to the following problems: first, the exposure determined after obtaining the metering value should be centered on the middle gray tone required by the picture, and the details to be preserved should be within the range of positive and negative brightness. Second, any photometry is based on the grey board condition with reflectivity of 18%. For example, shooting a flower with a tree as the background in the sun, we can do this: In order to avoid the dead white without details on the shot flower, we'd better prepare a white yarn to soften the sunlight shining on the subject, so as to reduce the light-dark ratio, and ensure that the light-dark part of the flower is within the exposure tolerance range and can also show enough details.
