I learned how to create a nadir in a 360 film on YouTube and did it twice this semester (team project and final project).

• Use Photoshop to design a nadir:
• create 3 layers with 1000 x 1000 pixel and maker sure one layer is transparent
• draw a circle in second layer and add text in third layer and adjust  the background color
• save it as PNG
• open it again,  filter - distort -  Polar Coordinates - Polar to rectangular
• image -  image  rotation - Flip canvas Vertical and clip Flip canvas horizontal (if your nadir has no text and has only one color you  can skip this step)
•  save it and drag it to your video (make sure all clips have the token)

I also learned how to use  Ambisonics microphone for final project. I went to Doug's workshop to learn how to record and learned how to edit in Premiere Pro on YouTube. It turned out to be successful in final project
