Here's a little bit about aspect ratio:

The "secondary ini file" that Peter mentioned is set up for a 1.33:1
Academy ratio
which means if you have a frame that is 1 cm tall the width is 1.33cm .
In the case of Peter's example above you'll need to determine the
correct aspect ratio
Or you'll get a very squished looking image. So to figure it out just
divide
100/400 = 0.25:1 aspect ratio and then enter it in your right vector
like so:

camera {
  location <blah,blah,blah>
  up    <0,1,0>
  right  <0.25,0,0>
  look_at <blah,blah,blah>
}

I personally like 2.2:1 (70mm flat) and have several resolution sizes in
my Quickres.ini .
