Converting Super8 Camera: Vertical Image and 2.35 Mask

[Alexander Boyd]

For an upcoming project I'd like to do the following two conversions to a super8 camera:

 

- 1) rotate the image 90° so I'll be shooting a vertical image in fact. Obviously, the easiest way would be to attach a handle and just hold the camera at a 90° angle. Just wondering if that could negatively influence the movement/advancement of the film?

 

- 2) since the final output will be in 2.35, I'm wondering what the best way would be to correctly frame for that aspect ratio? Any easy way to attach a mask?

 

Thanks for your time and help, it's much appreciated (and needed) ;)
