Directions Unit- Difficulties during filming. (And fixes.)

Yesterday was the 3rd shoot for my film "A Journey Through Freedom." Although I am confident that I will be able to complete all my work on time, I did come across quite a few problems during the filming process which I had to overcome.
Firstly, my original idea for the scene in which I wanted to film at the Maidstone Television Studios was that I wanted the scene to be filmed in a corridor close to one of the studios. The corridor itself was perfect for the shots I had in mind, as they are bright white and look very sterile, which was what I wanted for this particular scene. When I went to film the scene however with my actors Chris and Andy, I found that the corridors were locked and inaccessible, meaning I would not be able to film there.
I managed to come up with a similar idea however, using a stairwell in the studios that were also bright white. Although I wouldn't be able to pull off some of the shots I really wanted to create in the corridors, I still managed to collect a lot of the visual material I was after.

Another problem I came across during filming, was that the equipment I was using (A Canon 7D with attachable Rhode Mic) didn't seem to record any audio for a lot of the scenes I shot. This could have been avoided had I been viewing the footage as I recorded, and I would have been able to make the appropriate changes to the equipment settings, but since the time has passed for this, I feel that a voice-recording session and some foley work may be able to cut it.
Another problem that occurred during the shoot was the weather. Originally, I wanted to film a scene where Andy's character receives some blue-prints from Chris' character (the package), but since I didn't want to re-use the stairwell set, and since the script we were originally provided with clearly states the package scene takes place in an exterior, I felt it was appropriate to film outside. Outside however- it was raining. This provided quite a few problems.

• Rainwater gathering on the lens, obscuring shots and potentially damaging the equipment beyond repair.
• Inconsistencies with the characters clothing (wet one minute, not so wet the next etc.)
• General uncomfortableness for everyone involved.

Since the costume I provided Andy with was nothing more than a thin-white t-shirt, I am sure he was very cold and uncomfortable during the shooting of this scene.

I feel I have learnt a lot about problems that could occur during shoots in this stage of the project, and I feel that I will become a much better film-maker because of it, and take a lot more care and precaution at checking I have all the footage that I wanted to collect in future shoots.
