Background Image setup

Does anyone have instructions on how to take photos to use as background images?

From my experience, I took 3 full body shots from a tripod: Front, Left and Right, if I align the body to size, the head is too small, on the Model, it seems the full body shot may not be to scale, as if I need to take two or more shots and stitch them into one, like a panoramic, since the perspective is from the camera, it seems my camera setup is all wrong, if I take a close up of the head, it seems to work better, but then the head looks to small on the body, seems like a no win situation, I am not sure how to deal with this, anyone have any idea how to take photos that can be used for backgrounds that actually work well, if so can you share your experience on how to setup the shots.

Update:
It seems like I need references lines that might match the lines in MH, not sure what size to make them so the reference markers would work.

Have a look at http://www.free3dtutorials.com/female-figure-modeling-tutorial.php and the other tutorials on this site. Short summary: Scale and align your photos. Important body parts should match in position and size. Have a look at the link to see what I mean.

But, you'll run into trouble once you try to use your aligned reference photos in MH (http://forum.makehuman.org/viewtopic.php?f=4&t=11107).

It's important to avoid perspective distortions as much as possible. With a photo camera, you can achieve more parallel projections by zooming in and stepping back from your subject.
Lenses at 50-200mm is often used for portraits because it reduces the perspective distortions a lot and "compresses" the facial features (the face becomes less wide and nose becomes thinner).
In general: the further you zoom in, the more parallel the projection becomes.
