Final Project: Dolly Zoom & Tilt Shift

Methodology

For this project, the goal was to practice the dolly zoom effect. The premise of the dolly zoom effect is that zooming and moving the camera have different effects on the scale of objects in the scene.

Zooming scales all objects equally while moving the camera will affect objects closer more so than thos farther away (due to parallax affect).

This means that we can keep an object the same size in the image by zooming and moving the camera; however, this will affect objects at different depths much differently.

Methodology

The process of applying the tilt-shift effect is to simulate a higher depth of field than would be present at the scale the image is actually at.

This is done by applying a gaussian blur to the entire image and then creating a mask to smoothly transition from the in focuse to the out of focuse image. By defining a line of focus, it is possible to simulate a depth of field effect as the objects on that line will likely all be of equal depth.

An additional tweak made was doubling the saturation of the image. This was done to add a more toyish element to the image as childrens toys are often very colorful. (it however made some too colorful)
