Vertical Shot

Introduction

The dolly zoom is an in-camera effect that appears to undermine normal visual perception.The effect is achieved by zooming a zoom lens to adjust the angle of view (field of view/FOV) while the camera moves toward or away from the subject in such a way as to keep the subject the same size in the frame throughout. In its classic form, the camera angle is pulled away from a subject while the lens zooms in, or vice versa. Thus, during the zoom, there is a continuous perspective distortion, the most directly noticeable feature being that the background appears to change size relative to the subject.

Process

I used the camera Sony ILCE-6000, with lens E PZ 16-50mm F3.5-5.6 OSS. The focus length range of this camera is 16-50 mm, comparable 35mm focal length 24 - 75 mm. With this camera, I shot several toys at home. To make the dolly zoom effect, I started from the maximum distance from the object and maximum focal length. While moving forward, I reduce both the object distance and the lens focal length, to make the object same size in the image. In this way, the field of view increases when I moving towards the object.

The difficulty I encountered is to keep the target object the same size. To resolve the difficulty, I used the small rectangle coordinate in the camera screen to roughly measure the object size each time. Another difficulty is to keep the sample angle when shooting the object. To achieve that, I put both camera and object on a plane surface, like a table.

Move the Camera VS Move the Object

I tried different combinations of moving the subject and camera. We can see from the results that these two results are pretty similar in how the background changes, but different in how the bottom sheet’s patten changes, so that we can tell from the second gif that the little chicken is moving forward.

Failure cases

In the beginning, when I didn’t settle on camera on a plane surface, the shooting angle constantly changed and the position of the object in the image changed as well. So the results are not so ideal. Here are some failure results:
