Yes I am using the 24mm ts-e mounted on a 5DII. To achieve one point perspective I would have to face the space in front of me face on where everything is parallel, perhaps stand in the middle also, correct? What do you mean by shifting the lens diagonally? My lens only shift on one axis, either horizontally or vertically, but not both.
But you can rotate the lens to achieve shift on both axis, kind of a pain but workable.
This part is clear. Based on this I should restate my question, how do I photograph interiors in two point perspective and maintain natural looking converging horizontals? Emphases placed on interior because I do not seem to have a problem shooting natural looking two point perspective exterior pictures (architectural).
Ah... if you intend to shoot the interior as a 2 point, then your horizontals are going to diverge, no way around that. You can alter the angles of divergence to what feels acceptable by adjusting camera height as well as your rotation to the scene. The trick is often just to get the divergence to feel balanced to avoid "falling-off-the-edge-of-the-world syndrome" You're probably not seeing this being so exaggerated on your exteriors simply because of your proximity to the scene.
Also, on this interior, while your low camera angle adds drama to the shot, it also exaggerates the awkward, tilted feel. Then again, you could have compensated for that by shifting up. The ceiling is interesting and your composition leaves me wanting to see more of it. All that floor in the foreground is just dead space. "If it's not adding to the composition then its taking away from it." -to quote one of my mentors.
Too much floor, not enough ceiling... lacks balance... unbalanced compositions disorient the viewer, creating spatial confusion... even if the camera IS level.
