John, if you meant the last link to represent a pic with creases in the
background I don't see them. It looks good from here. :)

From what I've seen, most are done using a technique known as an 'infinite
background'. Basically, a piece of poster board, bristol board, paper,
sheet etc. which starts on the floor or ground and curves up onto the wall.
Thus, no corner seam of any kind. Some photography and film studios have
these walls built into the floor/wall of the building. I've seen them used
for a variety of effects.
I believe the other part of the equation is using a macro setting on your
camera. This causes what is known as a shortened 'depth of field'. In
other words, the camera can only focus on a very small range of distance in
front of it. It can only focus on the object OR the background, but not
both at the same time. Thus, if the object is IN focus, the background is
slightly OUT of focus. This helps to create the effect that the background
is sort of not there.
I'm sure there are other techniques that can be suggested, but these two are
the ones I'm most familiar with.
Best regards,
Allan B.
