How to add visual impact to photos?

Although with the increase of distance, shooting long-distance objects becomes less and less, so do straight lines and parallel lines. Although the lines keep the same distance from each other, they seem to be somewhere far away, and they converge into one point. At the same time, the brain still understands that lines remain straight and parallel. That is to say, although the eyes see one thing, the brain still tries to explain what it looks "right" because it should be.

Because photography is actually the fixation of what the eyes see, in order to give people a sense of reality, you need to keep a sense of the depth of the scene space. In addition, the good depth and volume of the image make the viewer have an indescribable emotion and sense of existence when watching. You can use perspective and other techniques such as depth of field and framing to create this effect.

In photography, perspective is a technique to show the three-dimensional essence of an object on a plane two-dimensional surface. The observer's brain tries to interpret the picture, analyze the connections between various objects in the picture, and try to determine their distance from the camera.

So how do you add spatial depth to photos?

First, linear perspective

This is the most commonly used perspective type, which is used for photography, and its characteristic is that lines converge into one point. Since most straight lines are parallel, the farther away they are from the camera, they will meet each other until they converge at one or more points, if they are far enough away from the frame boundary. These lines are mainly diagonal lines, giving people a sense of movement and movement. Eyes slide along these lines and accurately perceive them as the spatial depth of image propagation.

Wide-angle lens can enhance the linear viewing angle, because it covers more space, that is, we can capture more lines from the foreground to the rear. On the contrary, telephoto lenses limit the number of lines that fall into a frame.

A telephoto lens will produce different effects. The influence of perspective distortion when the distance between objects is "hidden" and it seems that the objects in the background are closer to the objects than the actual objects.

Linear perspective is also influenced by measuring angle. The perspective view will look different according to the height of the measuring point relative to the object.

Please note that linear perspective does not necessarily mean the fact that there is a straight line. These can be curves, S-shaped lines.

Second, the stereoscopic perspective

In fact, this is a linear perspective, more accurately, it takes advantage of the fact that the object in the camera is farther away. If you have a picture, it shows that the road is retreating in the distance, and the light poles look huge in the foreground. The closer the horizon is, the fewer they will be until they disappear completely.

This perspective is suitable for objects of the same or similar size at different distances from the camera. Because people's brains will still receive information of the same physical size, visually, the fact that they look different puts them in the signal and depth that makes them feel space.

The following photos are excellent examples of linear perspective (horizontal line) and stereoscopic perspective (vertical line and the same architectural elements). As you can see, on the whole, the sense of space depth is well conveyed.

Another good example is a popular story about the spiral staircase, when the photographer removed it from top to bottom. On the one hand, there are linear views, on the other hand, there are fewer and fewer stages that are considered equal (in reality) until they can't be distinguished, thus achieving the depth of the scene.

Third, the aerial perspective.

Aerial perspective (also called atmospheric perspective) is mainly used for landscape photography, especially when shooting blurred scenes.

Shooting in foggy days or fog will emphasize the shape and outline of the object and increase the depth of the scene. Objects close to the lens are clearer and brighter, but the farther away from the lens, the more blurred and dim they are.

It seems that several scenes are superimposed in the picture. Change the key and contrast between the first layer and the next layer, and send the information that these layers are separated from each other to the brain. These layers are divided into different planes and create a sense of depth.

But when using atmospheric perspective and telephoto lens, don't forget to use tripod, because this kind of investigation is usually more sensitive to the slightest camera fluctuation.

Clouds and cloudy days in winter are the best time for aerial photography, but hot fog in summer or low clouds in rainy days are also suitable.

Please note that in these days, complex lighting conditions will deceive the camera's exposure instrument and make it think that the scene is brighter than it really is.

Therefore, it is very meaningful to introduce small positive exposure correction to compensate for this "electronic illusion" or manual mode shooting, analyze the results and choose the best camera settings.

Four. Tone and color perspective

Tone viewing angle is related to air. It works on the same principle as dimming and contrast. The darker and more saturated the shadow of an object, the closer the eyes feel, the brighter and the lighter-the farther away. Putting dark saturated objects in the foreground and fading in the background will also increase the depth of the image.

So are words and colors. Warm colors (red, yellow and orange) are considered closer, while cool colors (blue, purple and green) are often removed. So put a red object in the foreground, blue or yellow in front and green in the back-we also increase the depth of space.

Verb (abbreviation for verb) depth of field

The depth of a clear description space (GRIP) is based on the differences, fuzziness and fuzziness of obvious and detailed objects. Our brains will automatically perceive that the closer a sharp object is, the more blurred it is, and the farther away it is is their consciousness.

For example, take a picture of a person against the background of a brick wall, f2.8, and focus on a person. He or she will be sharper than the wall itself.

Now let this person take a step back and continue to pay attention. The farther your model goes, the more blurred the wall behind her.

Try to determine the moment when the difference between the depth of the picture and sharp objects and blur is the greatest.

An intransitive verb has no frame.

Cropping the main object with the foreground object means creating a "frame" for the picture from the foreground object. This is a very effective way to increase the volume. Let the audience enter the picture and increase the sense of movement and action.

Therefore, we consider some simple but effective methods to provide the volume and depth of the image. They will make the audience more interested in your photos and turn a plan into a huge one. If you analyze these methods, you will find that they are closely related and each method has another element. This is a combination of methods-a way to make your photos really amazing.
