In considering an arca swiss rm3d(i) vs alpa vs perhaps a full technical camera (e.g. mline2), I'm wondering whether the 5º tilt on rm3d(i) will be sufficient for landscape photography. I have never played with tilt so I have no idea and would appreciate any help from those who are used to shooting landscape.
In what kind of scenario would more than 5º tilt be required? I have looked at the scheimpflug diagram and I would imagine that the distance between the camera and the nearest object will not affect how much tilt is required, but rather the relative angle of plane of sensor/film vs the 'ground' (assuming a flat ground here), so in this case, more tilt would only be required when photographing a valley from up above i.e. the 'ground' angle is pointing downward rather than flat.... am I thinking along the right line here? If that's the case, getting back to the original question, would 5º be enough (for a 'flat i.e. horizontal ground) or would more be required... and what about the terrain that goes downward?
