Hi,
I have a problem with about 20% of the building photos I take.
I realize I may be nitpicking here, so bear with me.
I notice that in the photos shown below, one side of the photo is perfectly vertical, while the side closest to the camera is not; it is usually keystoning, indicating that the camera is not level.
Camera is a solid monorail, tripod is solid too.
I line up the camera's rail to the leg of the tripod that faces out, then level the tripod head (3-way), then level the camera.
I use a good bubble level, made in Japan, for these kinds of shots, and I follow what it says because the bubble levels on the camera don't read the same all the time, and I don't use the GG grid for aligning, as it may be installed at a slight angle.
What am I missing here, and what am I doing wrong? Why is only one side askew?
Thanks in advance.
