Project 1 - Behind the Scene Footage of My Artifact

Tsz Ng (Oscar)

Description:

I started out finding some interesting images thatI like. Then I decided to do a theme on time and space. You will find three images below with an image mask next to it if there is one.

Tips: Move your cursor over the original image to see the result after each mask is applied.

Image 1:

This is just an image of the Earth from space looking at Africa. I simply just cut out the earth to be a foreground object later on.

Image 2:

This is a 3D art work of some sort. There is a light shinning down in middle making it look like a portal or gateway to some place. I cut out the middle part surrounding by the stones, so that I can have a different background.

Image 3:

This is an abstract vortex artwork. It will be used as the final background.

Image 4:

I just cut out the person along with the shadow to be another foreground object.

 

Procedures:

  1. Placed the portal (image 2) in the final image.
  2. Resized the earth (image 1), put it in the center of the portal, and adjust its opacity to be about 80%.
  3. Cmpressed the vortex (image 3) vertically and put it behind all the images to show through the hole in the portal.
  4. Used a Gaussian filter to blur the mask of the portal (image 2) so that the transition between the portal and vortex is smoother. Also, this smoothed out the edges of the vortex.
  5. resied the person, lowered the brightness, and placed it in the entrace of the portal.

Result:

This is a time machine that allows you to see the past or the future. The vortex represents the twisting of time and space from below. Images are displayed in the center. The sunlight reflected by the Earth illuminates the entire dark portal. There is road that allows you to walk up close and look the images.
