How did the movie change during filming?

  At the start of the film we set out with a very complicated idea and had little idea of how we were going to be able to achieve our goal, we did not realize how long it would actually take to film the film and we didn't take into account the actual setting of the film.
We had lots of problems with the setting of the movie, this was because our preliminary idea of filming in the morgue in Chertsey had to be stopped because the day before we filmed there we found out that the morgue was closed for renovations and that no-one was allowed inside or it would be a criminal offence and a fine.
This meant we had to re-think our whole scene as the morgue was very spacious and therefore it would be hard to replicate the space inside the building. Seeing the morgue was shut down we had to look elsewhere to film, this proved to be difficult as all the creepy looking locations we found were either unreachable or un-achievable.
Therefore we decided to film at my house seeing it is an old cottage and therefore it retains some of the creepy factor. It also has lots of cracks and a relatively big dining room where we could do the Ouija scene and it would look quite ominous and creepy with the idea of the candles and the match bringing creepy lighting to the forefront.
The change of scenery definitely impacted onto to our preliminary idea of what shots we would implement into our film. however we tried to work around it and involve the shots we first wanted just at different intervals or different positions. This was especially important when considering the 180 degree rule seeing we don't want to disorientate the audience on where about the characters are in the scene.
The end of the film stayed the same as what we previously wanted with the candles getting blown out, everyone disappearing  and then the match scene where it gets blown out at the end with the monster coming into shot and blowing out the match. However it didn't all go to plan with shot types, we can see this because our initial ideas had lots of birds eye views of the group, we realized shortly into filming that this would be nearly impossible to film as we do not have the correct equipment to do it outside, on the inside however we could get high angle shots but not a birds eye view as the ceiling was 8 foot high and we wouldn't be able to see the screen whilst filming.
