Deep Understanding of Photo Perspective

Do you know how to control the perspective and distortion of photos? To master this knowledge, we must first know the factors that affect perspective.

What does perspective mean?

Perspective is a very important photographic language. Controlling perspective and distortion is very common in photography. Through different perspectives, we can express different emotions and atmosphere. For example, strong perspectives can make exaggerated sense of space, while weakening perspectives can make the picture more compact. Perspective is the spatial relationship of objects. When we shoot, the exaggerated lengths of different objects from far to near describe the strength of perspective. Different angles of shooting, perspective will also be different, the change of perspective is not linear.

Standing at a distance and shooting with a long focal lens can create a compressed perspective and make the picture more compact.

Besides angle, how can we adjust perspective?

Photographers should consider the angle and distance when shooting. Distance is also an important factor in changing perspective. Taking the same range of scenery, using a wide-angle lens to shoot in close proximity, you can take pictures with obvious perspective, while standing at a distance to shoot, you can compress this perspective, space will be very compact. The effect of shooting the same scene varies greatly with the perspective.

_Make parallel lines twisted, exaggerate the linear perspective, and make the object appear very large.

I always think that the focal length of the lens controls the perspective, the wide-angle lens has a strong perspective, while the long-focus lens compresses the space and weakens the perspective. Is that right?

The only factor that affects perspective is your location. But if you want to photograph an object at different distances and keep its size unchanged on the screen, you have to change the focal length. With a wide-angle lens, you have to be close to the subject. Because the wide-angle lens has a wide shooting angle, a large number of scenes in the foreground and background are taken into the lens. If you want to use a long focus lens, you have to widen the distance between you and the subject. At this time, the scene in the foreground and background will change greatly. This means that when you use different focal lengths to photograph the same object and make it uniform in size, the foreground and background of the picture will be very different. This is due to the change of perspective and shooting angle. The telephoto lens can capture only a small part of the background and is suitable for close-ups. Wide-angle lens has a wide angle and can cover more background.

_Using long focal lenses to photograph buildings from a distance can create a sense of almost two-dimensional plane.

_The effect of three-point perspective can be produced by shooting buildings up close. (What is a three-point perspective? See the "in-depth explanation" below.

So shooting from a wide angle means taking an exaggerated perspective?

Yes. Using the wide end of your lens, you can take an exaggerated perspective picture, but you must be close enough to the subject. When using wide-angle lenses to shoot scenery or street scenery, you need to look for a prospect where there are interest points and layers in the picture, otherwise the picture will appear empty.

In some pictures, the winding paths converge at one point. How did this be taken?

Because of perspective, two parallel lines in depth will converge to a convergence point in the photograph. If you find the right angle, you can take a scene where they intersect at a point. This point is called vanishing point, and such a photograph will lead the viewer to a distant place, such as a winding path or a flowing stream.

Under what circumstances do we need to compress perspective?

Compression perspective can make the objects on the screen more compact and closer. For example, when shooting a building, the gap between the two buildings is smaller and the form of the photos is enhanced. When compressing perspective, we need to stand far away from the subject and use a long focus lens to close the scene. Compressed perspective can also be used to photograph tiny objects, such as flowers, so you can make the distance between flowers closer.

_These two pictures have different perspective and different effects. The left picture uses a 24mm wide-angle lens, which is very close to the model, while the right picture uses a 200mm lens to shoot from a distance. You can see the background changes very intuitively.

Does perspective have any other effect?

Perspective can also create more interesting images for you, causing visual errors and illusions. For example, many people have taken pictures of the Leaning Tower of Pisa, which is achieved by using the perspective of photos. In fact, the distance between the subject and the building is very long.

Because of the perspective relationship, all the parallel lines in the depth of a scene converge at a point in the distance. We simulate the perspective effect with the model. Perspective can make the building more three-dimensional, also can express the depth. Photographers can get different perspective pictures through different lenses and different shooting angles.
