Creating A Story Board

I decided to create the story board to give me some direction. It allows me to have a good idea of how the production of my film will go, and the way in which it would be most time effective to film the trailer.
When creating the story board, I have found that trying to think about how you are actually going to film the final product is very difficult. With little or no filming experience it has been an eye opener in the difficulty in envisaging what you are trying to portray.
I am aware that some of my clips in the film trailer are quite optimistic, and although I will try to do the clips as I have drawn them into the story board there is a chance that it will not look right and I will have to think about and change the way I film those certain clips. The shots which I can see problems are shot 25 when the two are laying in bed together and the camera is above them looking down. Also the circling shot of the couple holding each other in the final clip, number 31. Although this can be done I am aiming to keep the filming looking professional, if I find that the circling around the couple is jerky and does not look like high quality I will change this to a still shot.
I have also realised how long filming is really going to take. Before beginning the story board I had the idea in my mind, however I did not understand length of the process, filming a 1 second clip might take up to an hour because of preparation and repeated takes, this is why planning everything is key. I am hoping that the fact that it does take so long to film will not affect the continuity of the film.
