The vertigo effect, or dolly zoom, is an in-camera effect that can be created by moving a camera towards or away from a subject while adjusting the zoom so that the subject remains the same size in the frame. Therefore, the vertigo shot results in a sequence where the background appears to change in size relative to the subject. To recreate this effect, I used a DSLR with a zoom lens and shot the subject against a cluttered background.
Below are my two dolly zoom sequences as well as the "Bells & Whistles" animated gifs.
The tilt shift effect is the effect of digitally simulating a subject to look smaller than it actually is. This effect can be achieved by first manually defining a focus line. Because it is impossible to recover depth information from a two dimensional image, we use the heuristic that objects on the same straight line are at the same depth. Next, the user defines the depth of field, the part of the image in focus, which is centered around the focus line. Next, the image is increasingly blurred around the focus plane to simulate the depth of field effect. This was achieved by incrementally applying Gaussian filters to the image depending on how far away the pixel is from the depth of field. Lastly, the saturation of the image was increased to add to the overall "miniaturizing" effect.
Below are the results of my code. On the left is the original image, and on the right is the miniaturized image.
