Vertigo Shot

The Vertigo Shot is an in-camera effect known as the "dolly zoom". To repliacte it, I slowly backed away from an object while increasing zoom, to keep the object center and roughly the same size.

Bells and Whistles: GIFs

I simply stitched them together to make GIFs.

Bells and Whistles: Moving Subject and Camera

1. Combination 1: I try moving toward the object while zooming out.
2. Combination 2: I stay stationary and move the subject away as I zoom in. Although this probably wasn't the point of the exercise, I thought it was cute how the deer looked like it was backing away... towards the edge. :O

Bells and Whistles: Computing Field of View

I assume a linear field of view, and use the width of my object (3.5in=8.9cm), closest distance (2ft=0.6m), furthest distance (9ft=2.7m), sensor width (22.5mm), and focal length (55-250mm). We then compute the following:

1. angle_of_view = 2*arctan(sensor_width / 2*(focal_length)) * 180 / pi
2. field_of_view = 2*(tan(angle_of_view/2) * distance)

We compute for both the close and far cases:

1. Close: focal_length=55, field_of_view = 2*(tan(angle_of_view / 2) * 0.6) = 33.9
2. Far: focal_length=250, field_of_view = 2*(tan(angle_of_view / 2) * 2.7) = 152.9

Oops

I initially misinterpreted the assignment and made very boring zoom-ins. I thought I'd include them anyways.

Miniatures

To create the effect of a miniature city, I increase "depth-of-field" by successively applying Gaussian filters outside a specified region. The below are several miniaturized scenes with linear masks. From left to right, we show the original image, image after depth-of-field, and image after further saturation:

Miniatures with Alternative Masks

Below, I try alternative, (1) more detailed, and (2) radial masks.
