there is one thing to note about the horizon: the wall/floor edge is obviously _not_ leaning to the left side because the camera was rotated along its z axis (at least not much), but because the camera was not facing the wall in a 90° angle. this is pretty visible on the bottom of the foreground bottle - which is straight - and even more on the vertical line of the power outlet in the wall (on the left side) which is also straight.cfrank78 wrote:T_3 you made the pictures. Thank you. But the "horizont" in your picture is straight. The original pictures in post 5 are not straight, at least the horizont. Have a look. I made my pictures exactly like the horizont was. I placed the camera so that the horizont and the object itself were like on the picture. The 3 pictures were made with a full frame camera 24x36mm.
since the photos gave no clear picture about the original rotation and direction of the camera, the angle of this edge is just misleading (and i did actually add a -0.5° roll); also, in the rebuilt geometry, this edge is not right behind the blue bottle like in the photos. so if - like in your own tests - you actually rotate the camera to mimic the angle of this line, this will of course lead to additional wrong impressions about the perspective.
my bottom line is, you should be able to recreate photos shooted with focal lenghts of ~35mm and up, but you need indeed to recreate the geometry and especially the camera position like it was in the original. take this not as critisism - you said the bottles example was just a quick test, but if it is not made accurate, it just gives misleading results...
. We all learned that. Thats our business
