Adding ND or Neutral Density will not make your image brighter if your ISO and Shutter Speed remain constant. It will actually have the opposite effect as it will darken your image by shielding 'stops' of light from the camera sensor.
The reason we use them is because like the GoPro Hero, The Inspire camera is a fixed aperture camera that remains close to wide open f2.8. Not being able to change this one must either increase the shutter speed to lessen the amount of light entering the shutter OR add layers of filtration to block the excess light. The Former will cause rolling-shutter/jello in your abrupt movement shots. ND will greatly reduce this by allowing you to shoot at a 180 shutter angle (ex if shooting at 24fps your shutter speed should be 1/50th (2x your frame-rate) 30fps = 1/60th and so on... Without ND filters you won't be able to lower your shutter speed this low in bright day light without blowing out your highlights completely.
Shooting in a LOG profile is a setting which allows for more dynamic range and latitude in post editing. Your image should be bright but not over exposed (check your histogram to make sure highlights are not clipping).
I will be putting up a color grading tutorial in Final Cut Pro - X shortly. Stay tuned. |
