Looked very very convenient... And can proof to be very useful in many situation. However, I would think that it can also be easy if you could take a couple of photos, one without your subject (eg. Model) in it, just the desirable background. Then blur it accordingly using PS. The other one with the model with white background. Then merge the two pics together. Cheaper that way, I think.
Anyway, if anyone want to do it on the cheap, just buy a plain colour backdrop, and a few cans of spray paints in different colour, paint your own bokeh backdrop,
I paint my own backdrop before, and here is a tips for you, the backdrop will be more realistic if you use more colours.
if you take a very close up look on a oil painting you will know what I mean.
If all your photos have the same background won't it look ridiculous..
If you use it for your own, yes.
But if you use it for your customers, customers want it the same as what they saw on others. Fyi, many wedding photographers bring their couples to the same spot, doing the same pose, same framing, composition. As customers want it this way.
Zeisser - nice home setup with the canvas. LOL
