We decided to do our maternity shooting ourselves rather than paying professionals. It's not too difficult to mimick professional effects with a decent photo-editor. And doing it ourselves makes it more personal. Plus, we can do the shooting whenever we wanted.
I've a bunch of ideas for shot poses but they require an indoors studio environment which we just don't have. I'll have to see if I can find a shop that would sell me a large piece of white fabric for cheap (to use as backdrop).
In the meantime, my wife and I decided to have some fun and went outdoors for a couple of shots.
