The Old Bean Bag On The Window Trick (79-365)
I picked up this 'Hugger Bean Bag' many years ago. Basically it is two bean bags sewn together in the center face of each. That way it 'hugs' the window when used like this.
And just to be safe when shooting this image, the camera strap is looped through the seat belt and held tight.
