Documentary Production: Camera format

To produce one documentary, it contains so many elements in order to produce it, as a film student who has been taking part in few production groups and also taking a role of director of photography (DOP). I personally prepare the short list or idea of how each short will be shot during the pre-production, but before I can design a short list first, I must know what kind of camera I will use for this filming and what format is suitable for the film and camera.  

When talking about camera format many of new film maker or anyone who done know about filming and edit most likely suggest me to film in 4K for the best quality images, but I personally follow introductory in thing that I have been taught because not every camera is capable of filming 4K, but if the camera is capable to film in 4K and what about the output. For this documentary I will use Sony fx100e this camera cannot film in 4K so the format for this camera is HD resolution 1920-1080 and frame rate is 25p and speed shutter at 50 double of frame rate it’s enough for me to have a good quality images. The reason of set frame rate at 25p it's becasue it is common frame rate setting that using in Europe. Other than images sound also important for this documentary due to this documentary is also contained an interview part so sound of the interview have to be crystal clear. 

For the sound I have chosen to use lavalier microphone in order to capture a perfect interview sound for the documentary, reason that I choose to use lavalier microphone is because this kind of mic is purpose build for interview so it will not capture any of location sound like the shotgun mic, because for this documentary sound of the location or the diegetic sound is unnecessary for my documentary.
