Changing aspect ratio without effecting camera

[Gedred]

Hi, I managed to do this by accident once, but don't know how to replicate it.

Hi there,

Basically, I have an image already that im happy with, however I want to add extra canvas (width wise) to the image. Whenever I drag the viewing window to my desired aspect ratio, it changes the camera, zooms it in and I can't get it back to where I want it.

Hope this is clear, I want to add width to my chosen viewpoint image without affecting the camera.

Thanks.
