To infinity and beyond

I was travelling in Subway we call as Metro and I had to interchange station. For that I had to got through a walkway which on both sides had automated travelators and in the mid path was just plain walkways. I first hopped on travelator, however, I could not get the perfect symmetrical images because of angle of view. Then I hopped on the mid walkway and tried framed the lines to the four corners of image as if everything was joining a point at infinity.
