Paul Aslop and his partner (she isn’t named in the video) discovered that they were expecting a baby then it was decided that the pregnancy would be captured in a stop-motion time-lapse. Instead of waiting for the birth to start clicking away they created this fantastic piece over the nine months. They nearly decided it was too much of an effort to capture sequential images over the gestational period, however, they persevered. I think everyone will be glad they did.
Well, almost everyone. The baby might possibly regret that this was created when it gets shown at every opportunity the proud parents have over the next twenty or so years!
