This photo sequence contains 7 frames. Each frame is a finite 1366 pixels wide but height was left to 
its own based on the crop.  I based the picture size on an email program's display window asuming that the 
picture would not be automatically resized to fit.  This technique kept the file size down, the largest 
being 672k making it easy to send and receive through email. All photos were taken with a 
Nikon D810.
