Introduction to digital photography

As a beginner, I may not know much about digital photography. Here, I will share a video about digital photography for beginners, hoping to help you.

Step 1: Make your photos have a distinct and clear theme, (Is it a person, a still life or a thing? You need to express it clearly, not ambiguous or comprehensive.

Step 2: A good photo must draw attention to the subject. You need the audience to pay attention to your subject at once, because this subject is the core of your expression.

Step 3: Make your photos more concise, and all the elements that can't set off your main body or even distract your attention should be compressed or excluded.

Digital photography skills of people

Many photographers in the world are famous for taking pictures of people. In their photos, do you feel that the people being photographed are all for you? Tell? A story or an expression of an emotion. Why do we often see that the photos around us are not infectious? This is the reason in many cases. Whether it's a single portrait or a multi-person shooting, before we make the characters vivid (or tell stories), let's look at the common mistakes and try to change them.

1 Single portrait

1) A simple way to prevent the portrait from deforming:

Some top photographers deliberately deform the portrait when taking pictures of great people, which is a high-level artistic expression. For mass photography, portrait deformation is a low-level and fatal mistake.

Step 4: The simple way to keep the portrait from deforming is to keep as far away from the position of the person being photographed as possible, and try not to use wide-angle lenses. Portrait photos are suitable for shooting with 8-9mm lenses.

2) How to get a shallow depth of field to highlight a character:

If the scene around a character can't help or set off the subject? Tell a story? We try to cut or blur the background.

Step 5: The way to get a shallow depth of field (to blur the background of the subject) is to use a large aperture and a long focal length as far as possible, and (if possible) keep the figure standing as far away from the background as possible.

3) Make your subject more natural

? When I photograph someone, I always want to avoid the way they are being photographed. ? Famous photographer John Loungard said. Obviously, it is very important for the characters to relax in shooting. When people are relaxed, they will show their feelings more naturally. If it is not a snapshot (or a sneak shot), people in life are usually uncomfortable (unnatural) when facing the camera, which requires communication to make him/her forget to shoot.

4)POSE essentials:

With the help of environmental props and postures, the image will be more vivid and not dull.

Step 6: Let the subject stand, bend, lean, sit or lie down according to the scene.

Step 7: Pay attention to the hand movements of the subject when applying the overall posture flexibly, such as touching the head, pulling the hair, stroking the face, taking off the cheeks, pressing the corners of the mouth, touching the neck, pulling the skirt, pulling the arms, akimbo, resting the thighs and pulling the feet (such as shoelaces). In short, the hand movements can be groped freely all over the body, and the core is to keep natural and help express emotions. In addition, you can also hold props in your hands, such as hats, glasses, scarves, books, cigarettes, football, a flower, etc., to activate the photos and make the image more vivid.

trick 8: when shooting a single portrait with POSE, you should pay special attention to the subject's head and shoulders. Usually, the head and body should not be in a straight line as far as possible, and the shoulders and feet should not be parallel.

trick 9: when taking a single portrait, the photographer should keep a distance from the subject in the daytime to avoid the deformation of the figure. In composition, diagonal method is usually the safest.

trick 1: if the subject is really difficult to pose, and the dress or figure is not good, please try to take a bust or a big photo, and the expression of the subject is the only thing you should catch.

5) Portrait shooting under special light (scorching sun, night, bright background)

11th measure: When shooting under strong sunlight, you need to pay attention to shading the object to avoid unnatural eyes, and use more side light to make the object sharp; Try to shoot people with backlight as little as possible. The sunlight on the lens may degrade the optical elements, thus impairing the image effect. When you need to shoot against the light, you just need to block the shadow on the lens, and don't let the shaded objects (such as hats, palms, etc.) enter the picture.

It's difficult to shoot portraits at night. Bad PP is either that the faces of the characters are too dark to see clearly, or that the faces of the characters are too bright and the background is dim due to the blunt flash. For beginners, simplicity can alleviate contradictions from three aspects.

the 12th trick: first, increase the sensitivity and turn off the flash (no flash is forced unless the camera's flash system is very clever); Secondly, let the subject try to keep his posture still in a bright environment (such as under a street lamp); Finally, use a slow shutter (preferably a tripod) to make the exposure enough for imaging.

trick 13: the background light is usually supplemented by a flash to make the foreground portrait brighter. If you can use a scattering flash, the effect will be softer.

When taking indoor photos, set the exposure with a bright background. If the flash is not turned on, the imaging subject will be dark. If only the subject is exposed and the flash is turned on, the subject background will also be underexposed; In order to achieve the natural effect, we can first measure the exposure of the bright background outside the window as 1/125 and f8, and then use the f8 scattering flash lamp in the main body (shoulder position) to balance the indoor and outdoor exposure.

snapshot and multi-person photo

1. Why is snapshot more attractive?

People's expression in a natural (or casual) state is the most real. In the eyes of photographers, some people call it? The truth? . Many outstanding photographic works are completed by snap shots, no matter whether they are taken by one person or many people. In real life, many photographers are confused that there is nothing to shoot. That's because beginners haven't really opened their hearts and put their cameras around their lives.

14th trick: Go to the street, theme activity places or the scene of emergencies, and capture the expressions and relationships of people inside and outside the incident. Be careful not to flash and shoot quietly, and use telephoto lenses instead. Ambush shooting is better. The speed of snapshot can be trained, but touching works can be photographed, and the true meaning lies in consciousness, feeling and discovery.

natural posture and creative modeling

1) In daily life, friends get together, relatives get together and children grow up, so it is inevitable to take photos to commemorate and record the atmosphere. This kind of conscious shooting activity makes the subject POSE naturally.

the 15th trick: taking a group photo in life, posing naturally to capture the atmosphere is not only your primary consideration, but also the relationship between the characters should be reflected incisively and vividly.

2) In addition to the natural POSE, all dramatic and creative pose photos can get a refreshing and brand-new effect. Successful creative posture is inspired by the understanding and creativity of life. There is no one model to teach everyone to do creative POSE, but you can try more.

photography skills of tourist scenery

There is no denying that some people buy digital cameras precisely because of photographing tourist scenery. But the facts tell us that the scenery photos taken by quite a few people are unremarkable, and it is even more difficult to collect them. A core reason? Is also a common problem for most people? They are lost in the dizzying scenery and can't focus on a scenery or scenery, which gives him the feeling that he doesn't realize (or can't grasp), which makes it more difficult to design the station (camera positioning) and picture composition to highlight the artistic conception or theme of this scenery.

1. What moved you and how did you express it?

Chris? Steele Perkins doesn't usually shoot? A romantic masterpiece? Coincidentally, British photographer Joe? Cornish also advocates making the scenery more thoughtful. He said? Only through extraordinary efforts can we transcend the actual content of photography and convey emotion, vitality and passion, even the metaphor and symbolic meaning. ?

trick 16: don't try to shoot all the scenery in a big and complete way. Make sure to shoot a subject. If other scenery can't be contrasted, compress or exclude it. Feel the subject silently and summarize it with an adjective. For example: take a picture of a strong bridge, an ancient village, a quiet lake, a sultry food market, a sad mother and a lazy dog?

the importance of shooting angle (camera positioning) in landscape photography

landscape photographers have a mantra: Good photos come out and wait. ? Through professionalism, we can see how important the angle (camera positioning) is for landscape photography. There are usually three kinds of angles, the most of which are flat feet, followed by backhand and prone shots.

number 17: the choice of angle is used to highlight the theme, as mentioned earlier? Adjective? If this angle can best reflect the theme (artistic conception) you express, then use this angle, no matter how far you have to go. For example, when shooting a waterfall, the three angles clearly show the surge (upside down), the breadth (straight angle) and the splendor (micro-overhead) of the waterfall.

Introduce several typical compositions

To a great extent, composition determines the realization of the shooting theme and the success or failure of the work. Composition refers to how to arrange people, scenery and things in the picture to obtain the best layout, the method of combining images and the sum of all means of prompting images. For beginners, this sounds quite complicated. Here we briefly explain the basic composition.

18th trick: On the premise of determining the subject and expressing artistic conception, there are usually several methods, such as herringbone, triangle, oblique triangle, vertical, diagonal, horizontal and curved.

the 19th trick: the proper application of the golden section. For beginners, it is essential to learn and apply the golden section technique. Many textbooks call the golden section composition another name? Three-three intersection method? At the intersection? On the golden section? The subject of expression is usually practical and perfect.

Most of the stupid cameras are imaged by central autofocus, so how to highlight the foreground (such as portrait) in the golden section has become a difficult problem. This requires the application of the half-shutter technique (in fact, most of the fool's machine operation manuals have this practical technique explained.

the 2th trick: first aim at the foreground with the center of the frame (let the camera focus on the subject you want to shoot), then press the shutter for half a minute, then move the lens, put the subject on your imaginary golden section, and finally press the shutter completely to finish shooting.

more suitable position and zoom

? Few photographers will give full consideration to the placement of the camera. In fact, only under the precise positioning of the camera can a good composition be produced. In any given perspective, it is necessary to determine whether the plane should be left or right, front or back, slightly higher or lower. All these will affect the relationship between the subjects in the scene, the obvious proportion and whether it is within the effective depth of field. ?

　? With the development of photography technology, the performance of zoom lenses is getting better and better, and you can't ignore their creative potential. But it is important for photographers to understand the influence of different focal lengths on the visual relationship, proportion and depth of field between subjects. Generally speaking, a wide-angle lens will widen the space, while a long lens will compress the space, but this is a misleading generalization. Like art? Wolff, Goran? Rohel and Jim? Bladen Berg, Young? Arthur Bertrand and Neil? Photographers like Ben Wei have taken unforgettable scenery photographs with 35 mm cameras. For landscape photography, it is usually a mistake to choose extreme lenses, and wide-angle, standard and short telephoto lenses are usually enough. ?

operating tips for imaging under different ambient light

Some people describe photography as the knowledge of dealing with light, which shows how important light is for perfect imaging. Aside from the importance of theme and composition (content layout), imaging quality is what most people want to improve most. The factors that determine the imaging quality are nothing more than the ambient light, the grades of cameras and lenses, and the operational skills of photographers. As you know, as the general public, operating skills are becoming more and more important in order to complete timely and high-quality shooting without artificial lighting, cameras or lenses.

I have to admit that it is almost impossible for an over-stupid digital camera to complete good-quality imaging in difficult ambient light. Happily, most of today's entry-level digital cameras also have semi-manual functions. Those technologies that help improve the imaging quality, such as? Aperture? 、? Shutter? 、? Exposure compensation EV? 、? ISO sensitivity? And? White balance? Finally, you can make your photos come alive.

for beginners in photography, the above techniques (concepts) are inevitably unfamiliar. Let's briefly explain them here? Aperture? 、? Shutter? 、? Exposure compensation EV? 、? ISO sensitivity? And? White balance? How does it affect photo imaging:

Do we put? Imaging? Compare it to? Water injection? The aperture is the size of a water pipe. Shutter? Is the irrigation time? Exposure compensation? Is it a clip that allows the water pipe to be large or small? Sensitivity? It is the depth of the bucket. The shallower the bucket, the less water is needed (sensitive to light and easier to image). Underexposure means insufficient irrigation, and overexposure means excessive irrigation. Take a picture and adjust it? Aperture? 、? Shutter? 、? Exposure compensation EV? And? ISO sensitivity? Equal variables, also filled with a bucket of water, you can adjust the size of the water pipe, the length of time, the size of the clip and the depth of the bucket. And? White balance? Control is to adjust the image so that the color of the photos taken under various light conditions is exactly the same as that of the scenery seen by human eyes. Digital cameras generally provide automatic white balance and several modes such as sunny day, cloudy day, incandescent lamp and fluorescent lamp. Beginners can choose the corresponding white balance mode according to the light environment, and if it is simpler, choose the automatic white balance mode completely.

Operation skills of common outdoor difficult light:

1. Shooting in hot sun:

Usually, portraits and panoramic photos are not suitable in this situation, because the light is too bright, and macro shooting is a very good opportunity.

the 21st measure: it is suggested to use a small aperture for shooting scenery in the scorching sun, reduce exposure compensation by 1-2 levels, reduce sensitivity, and adjust the white balance in the sun sky mode. It is better to have a hood.

2, night scene skills

The 22nd trick: A stable tripod is essential. Try to aim the focus manually at the bright scene, and then lock the focus for composition after focusing. Try to use automatic white balance less. Daytime? Or? Outdoor? Mode, forced no flash, priority exposure with aperture
