Do ND Filters Matter? No filter vs ND vs NDPL Filter

[@keith-knittel]

Which filters are you guys using most? ND or ND/PL? I find myself using a mix of both. Thanks for watching!

[@bitlong4669]

I also like using graduated ones, especially if I plan to capture sky with ground or close to horizon. Give good results with dark subject like a dark forest and bright blue sky.

[@mrpeterpumpkin48]

My guess is I will be using ND a lot, but I live on a lake and have a boat, so I’ll be needing a polarizing filter also.

[@diogogamba9338]

Depend situation, i use more ND-PL I think they correct the images better.

[@AntonioIndelicato]

Bought a set of 5 ND/PL Skyreat, I can tell how the color is improved by a lot! My advise is the PL are way much better then the ND only.

[@hooliganhalo4328]

I like to do over the water low shots, so definitely Polarized. Comes out so much better in post.

[@williamschwartz9283]

If you want to eliminate glare off a horizontal surface, (like water), align the filter vertically, (12 o'clock or 6 o'clock)- If you want to eliminate glare off a vertical surface, (like a glass building), align the filter horizontally, (3 o'clock or 9 o'clock)- 6 o'clock and 12 o'clock are physically IDENTICAL. Ditto 3 and 9

[@MontagoDK]

exactly .. i dont think he knows how polarization works :D

[@tylerjslattery]

the line on the filter indicates the direction of the polarizing lines. Polarizing is done by a series of very small lines in the filter that run parallel to each other. Changing the filter from the line in the 12 oclock to 6 oclock will not change anything (because the lines are parallel and run the entire length of the lens.) The polarizing doesn't work horizontally because the phase of reflected light is perpendicular to the surface. Most of the light is vertical and gets reflected horizontally and is why the up and down lines will cancel it out.

[@keith-knittel]

Very true and sometimes frustrating (especially with a drone) to get the polarization wrong. Thanks for watching

[@ChrisParayno]

For drone footage, only during mid day. Any other time, it's a hassle especially if you are shooting multiple locations with different exposures. A filter maybe perfect for awesome sunsets but once you turn around it maybe too dark.

[@keith-knittel]

Definitely location and weather dependent, but I agree. Sometimes in the morning in ohio if it's overcast, I don't need to use a filter at all. Sometimes I have to use an ND8 at sunrise because it's so bring. Thanks for watching, Chris!

[@keith-knittel]

Glad you enjoyed the video! I wanted to break it down but not be boring and too drawn out. Hope it helped and thanks for watching!

[@fwfeo]

From my experience in Photography using circular polarizing filter, it is a biased filter! I mean no matter with position you adjust it to, it'll cut off some glare in the scene. For example you can make the sky that is 90 degrees from the sun's position looks super blue and dark or make it look slightly brighter compared to the surrounding scene. It's a tricky filter but very enjoyable to use. I highly recommend it if you're shooting a bald guy with shinny head! You can cut the glare for your portraits quite a bit! It's also great for shooting through glass or clear water in nature.

[@keith-knittel]

It's a tough filter to use, and it changes with how you point your camera at the object. There is a fair bit of changing angles in the air while using one with a drone. It can be done, but it's definitely not a "set it an forget it" type of filter! Thanks for watching

[@elmono3939]

Well explained. Kinda wonder, why DJI decided to put in a f2.8, fixed aperture lens on this drone.They probably saved 2 dollars, but made us to deal with ND filters, lots of guessing, and high probability of ending up with overexposed footage. I would rather pay $100.00 more to have few more f-stops. Don't think that was a good design decision.

[@keith-knittel]

Hey there El Mono, some of the DJI drones (like the Mavic 2 Pro) has a variable aperture, but still needs ND filters to properly expose your footage. A non-fixed aperture definitely helps in those times where you need to swap ND filters to a stronger filter, adjusting the aperture can definitely save you there but ND filters are a pretty common tool to have for shooting natural-looking motion blur with your footage during the day. Totally see where you're coming from though. When flying the Mavic Air or mini series, I definitely find myself wishing there was a variable aperture.

[@disco.jellyfish]

For choosing an ND, I can actually recommend to point your camera roughtly in the direction showing the situation you want to be shooting in, set ISO to auto, choose the shutter speed you want and then try out different ND filters. Choose one that gives you exposure that looks right just from the image, an look for the ISO to not be at the total minimum but also not at the total maximum. If the minimum is 100, you want to choose a filter that allows you to be close to that but not straight on. You will want some buffer in case the area suddenly gets brighter mid flight. At least, that is for drones, which have fixed aperture. If you have variable aperture with a minimum of lets say f1.4, set the aperture to f4, ISO to the native ISO (lets assume its 800) and then attatch an ND-filter that gives you proper exposure. If the lighting conditions change, you optimally want to change the ND filter - that shouldnt be possible mid flight, so you will have to change the aperture instead. There is a clear right and wrong in this. The right ND filter is the one that gives you proper exposure.

[@amateurvisser]

This is probably the best explanation I've come across. Thank you.

[@ZayasRaymond1]

Sold me on the polar pro filters. Was going to get a cheaper set but I love the quality of the polar pro’s.

[@keith-knittel]

Filters are tough, since they go in front of your lens, cheaper ones can have a color cast or blur the image when you just want it darker. I’ve been really happy with the polar pro filters so far!

[@bulversteher]

A pol filter is the same at 12 o'clock an 6 o'clock (or 3/9, 1/7, etc).

[@keith-knittel]

I agree! This video is meant to be an introduction to the different kinds of filters, so I thought showing a few examples would help drive the point of PL filters a little more. Just be aware that not all polarized filters are created equal, and some filters may have a cross-polarization effect if you move the polarizing filters too far. This is less of an issue on filters with markings or hard stops but still something to be aware of. Sorry for the late response - thanks for watching and pointing that out

A polarized filter at 12 o'clock vs 6 o'clock is the same thing. Light bouncing off surfaces is polarized parallel to that surface. Filters remove light polarized in a certain plane.

Polarization works better when it’s at a 90 degree. Great video thanks for posting

[@richardglazebrook8055]

A Polarising filter, by virtue of it's theory of operation, has also an overall filtering effect. On a clear sunny day, a blue sky provides the best example. Turn the filter and see through it , the sky/ cloud contrast change. The orientation of the filter {12 oclock} is invariably towards the sun. The effect extends to any surface that reflects light as would a mirror. ie water. Hence the reduction of the glare from sunlight over water. The effect is dependent on the orientation of the filter toward the sun, Fly fishers use polaroid shades to see their prey. Of course an actual mirror, being a metallized surface, reflects light; while reintegrating and removing the polarization. You will see no reduction in glare off a metallic surface. I don't think a polariser would necessarily be also a neutral density filter. It doesn't matter for B/W photography. But then I think back to the colourblind photographic plates of the past, with nary a cloud to be seen.

[@keith-knittel]

Glad it was helpful! I'm far from the first person to use this concept, but have been using it for years. You can also break this too! If you're shooting something fast like a car, and don't want as much motion blur, you can slightly bump up the shutter for less blur. Removing the motion blur might not be a good idea - but experiment around with your settings! It sounds nerdy, but it can separate your footage from everyone elses! Sorry for the rant and glad you enjoyed the video enough to like and sub.

@Keith Knittel i dont understand what the advantage of a normal ND Filter is. ?? Why not just use ND-PL all the time. if there is water reflections great, if not it would just work like a normal ndfilter. But obvs, i must be wrong .

[@keith-knittel]

There are some advantages to normal ND filters, one is cost. A set of ND/PL filters will cost more on average than single ND filters. Another, more common reason is ND filters are less complicated than ND/PL. They arent that complicated but many beginners don't take the time to figure out which is the proper polarization that they need, so they arent happy with the results when using a polarizer on a drone and don't get great results. I love ND/PL filters, and use them anytime I'm around reflections, although there have been a set of VND+Mist filters I've been using lately. Next I'm hoping for an ND+Mist+PL! Haha. Great question and thanks for asking, Matt!

[@mattduncan5500]

With 30fps you need less motion blur and with 60fps it is even less important for smooth playback. This is why I prefer higher fps, but it requires more pc power.

[@keith-knittel]

[@stantonkramer2986]

The question comes into play; is trying to get *some* motion blur worth giving up exposure adjustments with fixed aperture lenses with the only tool, the shutter speed? And with the ND filter the exposure still has to be dead on. So to some extent you're stuck anyway, having to depend on post production to fix minor exposure issues. And motion blur only occurs when you're closer to objects. So, IMO those pilots/filmers who are sensitive to motion blur, a better drone would be one with variable aperture like the Mavic 2 Pro, Mavic 3 or Autel Evo II or Evo Lite Plus. With variable aperture, if you think you need motion blur, you can throw on your best guess of ND filter set the shutter speed, and then dial in the correct exposure. And should the light change during the same sortie, just adjust the aperture again.

[@keith-knittel]

That does come into play, however cranking up your shutter speed on a sunny day to something high like 1/1000+ will start to introduce some stuttery-looking footage as well. With the filters, I can still adjust lower or higher than the 180 degree shutter rule. Like you mentioned, if you want more motion blur, you can "fake" that by slowing down your shutter to something even slower than you typically would if you're far away from your subject to "simulate" some motion blur. The beauty (and the frustrating part) is that there is no right or wrong answer. The guidelines are a good starting point to use most of the time but there are always situations where you can "break" the rules and get great results. Understanding the rules is the first part of knowing when to break them and you definitely seem like you know the 180 degree shutter rule pretty well. I agree that having aperture control is easier. I should make an update video to this using a mirrorless/DSLR and go deeper into how aperture plays a part in this. Thanks for the great comment and watching

[@robjeeves]

Nice tip about the frame rate mate. Not heard that one !!!

[@davidshuttmedia373]

Nice subbed! Just a side note, if you double the frame rate say to 60 and then use the 120 shutter angle that will give the 180 degree shutter if you slow it down, but if you don't slow it down then it will be a bit more staccato

[@keith-knittel]

Hey there David, thanks for the sub! I was under the impression that the shutter angle was determined at the time of recording. So filming at 24 fps / 48 shutter speed would be a shutter angle of 180, but also 60 fps / 120 shutter speed would also be a shutter angle of 180, regardless if you slowed it down or not. You can slow it down, but the motion blur will remain the same (more drawn out if you slow the footage down, but it would be the blur would be the same). I think the stuttering may occur if you're putting the native 60 fps footage into a 24fps timeline. Interpreting that 60fps footage to the 24fps timeline would eliminate those stutters, but you'd have to slow down the footage. I could be wrong here, but let me know what you think. Very good question and thanks for bringing it up!

[@davidshuttmedia373]

@@keith-knittel Oh no, I read what I said and worded it terribly haha, it's because most people edit in a 30p timeline even with 60p footage, so you're right if they slow it down it'll be fine, but if they edit in a 30p timeline with the 60p footage and don't slow down the footage to keep all the frames then 1/2 frames will be missing which will make the shutter angle for those shots at a 90degree angle instead of a 180 degree angle.

[@ExploringWorldYouTube]

Hello, thanks for your interesting video and thanks to share it. I need to ask a question please. I only make documentaries in 4K 50p on sunny days. Since it doesn't make much sense to use an ND filter with high framerate and Automatic Exposure, I was thinking to buy a CPL filter and always leave it on, without removing it. I like an image that is a little more contrasted, crispier and with more colour. I use D-Log M, do you think I'll get what I want with CPL filter? Thanks

[@keith-knittel]

I would look into using manual exposure if you're using filters of any kind - adding filters will typically darken the image and your camera may try to boost ISO or jump around. Locking your shutter to 1/100th shooting at 50p, you'll probably need an ND filter on sunny days to bring your exposure down. If you like the saturated and contrasty look, you'll probably want to use single ND filters (ND4, ND8 ND16, etc) and a CPL to get the best exposure and remove glare/increase colors. Unless you can find an ND+PL for your camera, what are you shooting on?

I don't want motion blur, what happens if i leave shutter speed on auto? I like using the hypersmooth feature.

[@keith-knittel]

If you don't want motion blur, use less aggressive ND PL filters, so you can keep your shutter higher, but not 1/1000 or something so it's not "jittery". I'd say shooting at 24 fps, keeping the shutter around 1/100 would eliminate most motion blur, but still keep the video from looking too choppy. 1/200 or 1/250 would start to look choppy to me, but do some tests before you go to Puerto Rico and see what kind of footage fits your taste

I think PL filters on a drone are pretty useless. I suggest to do some experiments with an SLR camera with a pol filter on a tripod. Make a photo of a car and try to remove the glare in the windshield to get a picture of the driver inside the car. You will notice the adjustment of the filter needs to be accurate but you'll also find out the angle of the camera towards the car is important. Move the tripod a bit and you'll have to adjust the filter again. In my opinion with a moving drone this is an impossible job.....

[@keith-knittel]

Polarizing filters are tough to work with for sure. I like using them because I film around water a lot, and it will help take some of the glare away so it doesn't just look like a giant sheet of reflections. That being said, it doesn't take all of the reflections away, and if it's not aligned properly you could get some weird dark cross-polarization. They are finicky filters - and sometimes if I don't feel like dealing with them on a quick shoot, I'll opt for regular ND filters. Thanks for your take and watching, Mark

[@EDSC_CANADA]

So when would I use an ND filter for a mirrorless camera? I use them to slow the shutter speed when filming but with a camera I can change the shutter speed and aperture to match the light... and still feel like I get good quality photos with a fast camera shutter speed. I find using an ND filter almost vignettes my photos and turns them a bit yellow...

[@markvermaat652]

@@EDSC_CANADA you are right. In general a ND filter isn't useful when you have control over shutterspeed and aperture. But in case there is a lot of light and you want to make a picture with a very slow shutterspeed by purpose ( i.e. 1 second) because you want movement in a floating river or something like that, you might run out of aperture possibilities. In that case a ND filter might help

Hi Keith. Basically I’d say the best practise for Polar Pro filter is to set the line to 12 o’clock to get the maximum polarise effect. Correct?

[@royevans4581]

Great explanation of this rule. Just a question about the rotating pl filter. Is it only to be moved to 12, 3, 6 and 9 positions?

[@keith-knittel]

Thanks for the kinds words! You can rotate the filters 360 degrees unless it's a "hard stop" filter. I just used the common 12, 6 and 9 as common positions

[@rangerrick8220]

Very good explanation - thanks! One question - what are the best settings and filter for eliminating jitteriness from med speed sideways panning motions on a normal sunny day at noon?

[@a.b.5757]

Thanks Keith for great video! What is still open for me, is following question - would you recommend using nd/pl filter on non-reflecting objects?

[@mazzonijacopo]

so many misconceptions on how polarizers work. BTW 6 and 12 o clock are both allowing vertically polarized light. there's no up or down. the results are exactly the same

[@keith-knittel]

Hey there Jacopo, this wasn't meant to be an exhaustive resource on how polarizers work. This is more of a visual representation of how different filters work in relation to your camera settings. I totally understand where you're coming from and maybe I can do a video on how polarizers work with your camera in the future. Would love to deep dive into how reflections and light works (not just with cameras, but in real life)

[@RokkarTV]

Dang dude, this was informative. Thank you for making this video :)

[@keith-knittel]

Glad you enjoyed it and thanks for the kind words!

How do we get the right alignment with ND/PL to achieve no relection?

[@keith-knittel]

If your lens has markings on it, check out the markings - typically lining up the markings or using it at the top of the lens will give you the best polarization. If not, it will take some experimenting. Thanks for watching

[@Mr10025897]

So what’s the point of buying solely ND filters? If you can basically just turn off the polarization from NDPL filters?

[@dzlfiqar]

how to decide the allignment of the polarization?

[@EricTheHiking]

Love your explanation ! Very clear !

[@BojanBojovic]

Strange, never used anything above ND16, while being at ND4 most of the time.

[@keith-knittel]

It really depends on how bright of an environment you're filming in. I live in Ohio, so my ND filters are typically pretty mild, but when I was in Mexico when the sun was closer to the equator, I had to use some serious ND filters to battle the sun. Thanks for watching, Bojan

Are there any self adjusting variable ND filters that uses a clip or something similar to attach to Go size cameras?

[@ralph9987]

What about a ND/UV Combo Filter for beach or ocean shots?

[@JustAnOldMan]

properly aligned polarized filter will let you see that 20' great white ready to attack a surfer

[@keith-knittel]

I mean, thats one way to look at it! Haha

[@a.b.5757]

Hey Keith, Have you tested and compared DJI and Polarpro filters? Is there any difference?

[@prmath]

When I go out in bright sunshine, my eye need filters so I grab my sunglasses. Out in the gulf, in need polarized and darker filters......sunglasses 😄👋🏼😄

[@raduchiperi4924]

The explanation is great! However, the footage seems choppy at times when turning or panning...I've heard some people turn off the caching on top of adjusting the shutter speed to be double than the frame rate

[@keith-knittel]

I shoot at 24fps, so the footage can appear choppy. I'm sure KZbin isn't helping out either. I've never heard of caching having anything to do with the shutter speed or frame rate though.

[@raduchiperi4924]

@@keith-knittel so I have a big problem with choppy videos or videos that stutter straight from the SD Card. I follow the 180 degree rule, I'm shooting at 24fps, my shutter speed is at 1/50 and added ND filter as well. I even turned off caching and auto HD sync. I'm using a Mavic Mini 2. I have no idea what else I can do. It's quite disappointing after investing money and time in this drone. Any ideas? You reckon that 24fps with 1/50 shutter is causing the problem and I should use 25fps instead? Or 30 fps with 1/60 shutter?

[@codywild8176]

@@raduchiperi4924 Try 25fps with 1/60 shutter and slow down 3-5% or try the same with 30fps and slow maybe 10%

[@keith-knittel]

@@raduchiperi4924 What computer are you editing with? If you preview the footage on your phone via the app, does it stutter? You need a very strong computer to playback and edit this footage

[@raduchiperi4924]

@@keith-knittel I can't previous the footage on the app as I turned off the caching. My laptop is pretty powerful, MacBook Pro 2020, i7, 32GB, should be no problem with it.

[@Rocketryman]

One thing you should get out of this is, we do not film. As was said in the beginning. Cinematic VIDEO. :-) Digital Video and Filming require different skill sets and different gear. It's why we can fly drones. Good luck doing it with a film camera attached. :-)

[@_brothersandsisters_]

Can I use a ND8/PL filter but leave the setting AUTO for the drone?

[@keith-knittel]

Adding an nd filter and leaving your camera on auto will likely introduce more noise with a higher iso. Wouldnt recommend using auto settings
