Transparent Wallpaper
Tuesday, September 13th, 2005

So a while back, Aurora posted an entry about some creative desktop wallpaper. A group of individuals have taken a picture of there computers environment without the computer screen. Editing the photo, they were able to crop the area where there monitor should be and reshape the image to fit on the screen. The screen was then displayed with the image while another picture was taken to achieve the effect of a transparent screen.
I have been wanting to try my hand at this for a while. I finally decided that I was in the mood for a quickie and went to work. My pet cat Gizmo was setting next to me. This cat never wants to leave once he has found a nice spot to set near me. What a perfect centerpiece.
The first image was easy. I just set up a tripod and took a picture. I placed my laptop in front of him and then took another picture. Now I knew what area to pull out of the picture. Now at this point, I could just cut out one picture and let the second picture show through - but that would be cheating. I needed to take a picture of the laptop with Gizmo as the background wall paper.
I pulled out a portion of the image that I needed and reshaped it to be a rectangular image to fit the entire screen. I used scaling and perspective transformations. I then loaded the image onto the laptop as the background. I then set it up to a screen saver too so that I could get a picture without all the icons and the start bar in the way.
The tripod was still in the same position from the first photograph, but the laptop was not. I had used the computer and moved the laptop to get to it. I didn’t even think before I took the picture. I forgot to line everything up! Of all the things to do wrong.
Gizmo at this point had spotted a more comfortable spot where the laptop wasn’t setting against him and moved himself away. It will have to do. I now have experience of the process of doing this. If there is a next time, I will put more effort into perfecting my technique.
