This was really interesting because using a green screen is something I had always thought about but never known exactly how to go about it.
Session 2
In this session, we were shown how to place our animation into After Effects and then composite in our chosen background.
The first ting to do was to import the image sequence of the windmill moving, interpret the footage and make sure the frame rate was changed to 12.
Once that was done, we used the Keylight tool to select a consistent looking area of the background.
This then tuned the background to black, and
allowed me to alter the lighting to black and white, which could then be adjusted so that the edges would become sharper.
This stage just made the object look a lot tidier and more focused.
We then needed to change the background to red, and use the pen tool to go around the object and the background. The darker areas at the corners needed to be cut out too, so we basically needed to go for the main centre area that wasn't effected by the lighting change.
Once that was done, it was time for the fun bit! I researched for a background in which the object could be placed. In this case, the Lonely Mountain. I scaled down the background and the object to their desired size so the windmill could be placed.
Something that needed to be altered was the levels, because I wanted the windmill to look as though it was fading into the clouds, so once again I used the pen tool so select the area. I did this by lowering the opacity so I could see the clouds through it and then drew over the rough shape, so that I could then change the levels of this particular area so that it gradually faded down.
I also played around with the lighting of the windmill because the lighting for this particular background is quite blue and natural, so I wanted it to look as though it was actually part of it.
