In order to produce a interview you will need a combination of skills/job roles, these responsibilities are shared by the producers, directer, interviewer, cameraman and music and lighting technicians. In this case you'll be doing all of these jobs yourself. In order to film an interview you will need to make preparations which include: arranging a guest, choosing your location, preparing your equipment and setting it up on location and a final briefing while making technical checks. Another tip is to always check everything before shooting and always take test shots before rushing into it and getting it wrong.
When filming an interview i would suggest that you should use the single camera technique, this means that you won't need to move the camera when shooting. When shooting you are either filming the interviewer or the interviewee, if shooting the interviewee you would generally shoot in a mid shot so that you just show their upper body. You could also do a two shot, this involves shooting both people involved in the interview. Another shot used would be a back cut, this is a shot of the interviewer asking the question which is shown on the other side of the interviewer. A very popular shot when it comes to professional interviews would be "The Noddy", this is a shot where they film the interviewee or interviewer nodding at the question or the answer.
When it comes to mise-en-scene in an interview it often depends on who the interviewee is as to how it would work/be used. An example of this would be at an awards ceremony where the press backdrops would have the appropriate logos for who was sponsoring the event, who was the host of the event and the name of the event. It's important for the backdrops not to distract from the main person being interviewed. It's important for the interviewee to wear plain colours so that it doesn't cause a strobing effect with the camera.
Framing is an element that you should consider when making a documentary as it needs to be done properly in order to get the right look. A very popular technique to use is the rule of thirds, this is where the screen is split up into 9 boxes on the screen, this helps to identify where to place the subject. when using this shot you need to line up one vertical line and the subjects eyes close to a horizontal line. you need to follow the lines so that they line up the interviewee with the shot, making sure they are in proportion to the background so that no errors occur.
Three point lighting
Lighting is a very important thing when filming and interview, lighting helps to get a professional look in the shots. Many interviews do not use the correct techniques when filming their interviews so in order to make sure you get the best Finnish you need to include the lighting as a main point. The most popular lighting would be the three point lighting, this is where you use 3 different types of lights these are the Key light, Back light and Fill light. These all have different uses, the key light is the main light that has the strongest influence on the interview. The fill light is the secondary light and is placed opposite the key light, this is used for filling in shadows and it is often not as bright therefore it helps moving the light further away from the interviewee. Lastly the back light is placed behind the interviewee this helps to prevent definition and highlights around the subjects figure.
One to one interview
One to one interviews are usually set somewhere that links with the topic they are talking about. Some of these interviews are often filmed with a green screen or might have a poster advertising the film or product in the background of the interview. Depending on where the interview is filmed would depend if the interview was to have background noise or not, if it was in a park there would be noises of children however if it was in a room it would be quiet with no noise. The editing of a one to one interview is often much harder to edit as its mostly done in one shot so not everything is perfect and the sounds might need changing.
