I think I understand the theory behind using ND filters.  I am planning on buying the DJI ND8 and ND16 for my Phantom 3A.

How do I know which one to use though??  Is it just experience and knowledge or is there a way the camera settings can tell me?

Thanks

I just ordered a variable ND filter 2-400, will see how that works.

This article explains, amongst other things, why ND filters are used and how to know which one you need. Maybe it can help you get started.

Variable ND filters are convenient but because they are made from 2 filter elements they are more likely to degrade the image quality.

That said, a lot of people probably won't notice that

ND Filters or use the setting in the camera in the App...once you start recording you can adjust the shutter speed and the ISO

shutter speed should be roughly twice the frame rate

Can the wheel on the remote alter these settings too, or just the EV? I notice the wheel can "click" but I have not figured out what the "click" does yet. I would much rather go through the wheel, over having to touch the phone.... Is there a good tutorial on camera settings, that i've missed?

yes...you push wheel in the change between ISO and shutter speed...shuytter speed = apprx 2 x frame rate

ie 2.7 - 30fps = shutter speed 60

u can also use manual mode in camera settings and then toggle ISO ...ND8 - 3 stops

ND filters are fiddly and a waste of money, if you get proficient with manual camera settings you can do away with ND's (neutral density) all together...for example when flying over water on a sunny day, you can change the camera settings to "sunny" and then control the exposure, white balance with wheel on RC...sun can reflect off water and give the video that light brown tinge in corners...experiment with it before spending money on a "trend gadget"

To keep your camera at the proper shutter speed and iso low you will need ND filters don't mislead people.

It really depends on the quality and look of the video you are trying to achieve.  If you plan on making anything of film quality an ND filter is an absolute necessity on the p3 camera because of its limitations.  If you are just buzzing around then it just a novelty.  The point of the ND filter is to allow you to more easily adjust your shutter to frame rate ratio within a reasonable iso.  I use the ND16 and ND32 most but, your mileage my vary.
  Try it all and go with what you like.

Also note, I don't know if this is true in the Go app,  but in the Litchi app,  if you hold down the wheel button for a few seconds,  it will let you adjust only the exposure value. Hold down again and it will let you control shutter speed and a quick press will toggle to controlling iso.  The litchi app will announce through the speaker what you are controlling with the wheel when you switch to it.

Don't worry, you will use them in the future. They are especially useful when shooting Video.

Do not listen to this person, as they clearly have no idea what they're talking about.

The only way to compensate for sunlight with no filters once you reach ISO 100 is shutter speed. If your shutter speed is way over twice your framerate (so 120th of a second if you're shooting 60FPS, 50-60th of a second if you're shooting 24/30FPS), you will get video that looks horribly staccato, and really bad rolling shutter effects. It will make your video look extremely amateurish.

If you want to see high shutter speed weirdness, look at the beginning of Saving Private Ryan (the beach scene); it's done that way to get a very ethereal, in your face, chaotic alien effect. It's very disconcerting, which is why the high shutter speed was chosen. Since that was film, there are no rolling shutter effects, but add in that effect (because the P3/P4 is digital) and it makes the whole thing even strangers and very ugly.  High shutter speed is VERY undesirable for normal shots.

Also I'm not sure why he's talking about white balance and such, as that has no bearing on shutter speeds.

I can't understand what you're saying. Regardless, your initial post regarding ND filters is still incredibly wrong.
