Shapes that help me

I have bought several packages of second-hand rails for my model train. To keep them apart, I draw several shapes on a board and put the vendor's parts number in.
To take a real wide angle picture I was allowed to use the camera and lens of Hanulli. I didn't get the real wide view, but probably because my board was too small. After all, the rails are in gauge N, so 1:160.
