So, I have the object and camera positioned perfectly. However, I can only see
half of the image. If I take the camera further away from the picture, I can see
all of it, but it is too small. I do not want to change the current point of
view on the object. How can I look at the rest of it. Or, how can I show more of
the image to the left.

   We need more information, or even better, a sample image and/or scene
code. Right now, I'm not sure what is your exact problem...

Here is a simpler version of my image. I want to see the whole box, but maintain
this current point of view without increasing the distance from the camera to
the box.


#include "colors.inc"
#include "textures.inc"

camera {
 location < 6, 2, -10>
 look_at <6, 0, 0>

}

light_source {
 <2, 3, -8>
 White

}


background{ Clear }


box {
 <3.7, 0, 2>, <-4, -.3, -2>
 pigment { Gray25 }

}

add 'angle 110' to see all of box.  not really a solution though.

Increase the camera angle to get a wider view.

I am trying to not zoom out. Is there not a way to show more without zooming
out? At the current distance, the image is much clearer. Zooming out would mess
that up.

forget angle, you need a non 4:3 picture, with a camera like


camera {
location < 6, 2, -10>
look_at <6, 0, 0>
up y
right image_width/image_height*x

}


and rendering option like

+H600 +W1600

beware, the perspective camera (default mode without modification) is going to show
strong deformation on each side with such ratio
