Technical Post: Green Screen

When using the Green Screen we experimented with very different techniques that each gave a different effect- some of which were desired and others that were not. One thing we found that didn't work at all was flashing lights while using the Green Screen as it created different gammas and contrasts which meant that keying didn't work efficiently.

None of us had ever experimented with using a Green Screen and so we found it hard to implement at first but after following the instructions we were able to do it, even though it wasn't to the best of our abilities. One thing we found hard was to remove the background correctly without leaving random segments that made the video look awkward- however, we were able to rectify this by using a background that wasn't affected by the change in colour- one that matched it.

We have looked at the different backgrounds we could have used and understand how each one would be implemented and how through keying you can duplicate images to make the final effect more tech-savvy and visually appealing. This allowed us to create a very simple, but effective, final product in our example as seen above.
