Yes I remember that you mentioned this. That's why I suggested to use a
rendersize and camera that matches the aspect ratio of the photo.

Yes this helps a lot to find a rough setting, but because of lens
imperfections it's not instantly perfect. Well that's what I found. When I
took this picture of the couch the camera had quite a wide view angle.
Straight lines get bend stronger when zooming out, which shows a serious
imperfection. CS2 has a nice filter to correct this bulging but I'm afraid
that such corrections do not improve correlation between the real life lens
and the calculated lens.

The only time I saw a good picture when a friend of mine took a photo of one
of my paintings with a technical camera with 4 x5 inch negatives. With this
camera the painting was perfectly rectangular.

Arjo.
