Hi CS members,

i am a rookie who just enter into world of photography. I found that Hoya has produced a special effect filter: NDx400 which reduces light values by 9 stops. Hence i would like to conduct a poll to find out who are the NDx400 users in cs.

Cs Members, senior and experts, please share your views about Hoya NDx400. big thks ;P

Hi

I'm using the ND400 filter too, got it recently. Still experimenting and exploring the potential of this filter.

Hope some more experienced user can share more about the ND400 filter. :)

Hi Taurean,

Agreed with you - hope that more cs members, senior and experts will share their views/advice about Hoya ND400 :sweat:

As the category of the filter suggest, this filter is used for special effects. It just enable you to use very low shutter speed even in broad daylight. There isn't really much to comment about it...

Not very helpful comment right? I can read it is special effect, but the website also provided very little info on the usage and what kind of photos etc.

Hopefully we have more people who has used the filter to share their experiences.

just order a 10 stop ND, it's equal to NDx1000 :cool:
to me, it serve 2 purposes :
1) shoot waterfall/fountain under strong sunlight
2) apply black card

Can enlighten me on this? :)
to solve HDR problem,
u can use GND (film and digital),
or bracketing then ps (digital only),
or apply black card (film and digital) :
tripod is a must,
use the smallest aperture (eg : f/22) and apply a ND to slower the shutter speed,
then swing a black card to block the brightest part of the picture to reduce its brightness

one advantage black card over GND is you can make black card in different shape to overcome different problem (eg use a triangle black card to shoot sunrise in a valley)

here's some useful link (in Chinese)

ND400 is a lot more than just a Gradual ND (GND) or a ND4 or a Circular Polariser. The use of a black card can get similar effects, though not entirely. I do use ND400s, albeit for specialised purposes. And the very few individuals who've tried it will know how far it adds to your picture in Singapore's different conditions (bright sun, sunny, cloudy, overcast, long exp, etc).

ND400 examples






That said, the ND400 is not an ordinary ND filter. Someone ever insisted to me that it is the same as a ND4 - it is NOT. It cuts a lot more light than the average ND filters. And its use can be creatively applied to more than just light reduction, if weather conditions are decent enough.

Those who want to get this, Lords Camera (ask for James or Kelvin) brings it in regularly. Apparently, the filter got very popular after this photo was shared on this forum....

Basically, it is as simple as the website mentioned. It cuts 9 stops of light enabling you to use very low shutter speed (400x lower). 1/400s in normal exposure will now become 1s.

Think.... slow shutter speed... very slow... basically moving objects (ppl, cars, etc) will virtually not appear in your photo if you shutter speed in in terms of secs or minutes.

Basically, I won't buy one. I will foresee it sitting in my dry-cab after the novelty dies off.

ND400 lets you play around with low shutterspeed. If individual could see that in mind, it will be innovative tool. Just like a Fisheye to give a different perspective.

Some of the uses of ND400

1) Create double exposure effect
2) Gradual move of light source from bright to dark
3) Slower shutter speed in bright sunny days
4)Shooting at the Sun/Sunset
5) Create 'diffiused' clouds effect

There might be more. I'll let other CSers to share more bout it. If not you can google and flickr around.

let me guess :
left side photo taken with CPL applied,
else the right side shutter speed wouldn't be 1/4 sec (provided light conditiion remain unchanged) :think:

I think the light has changed a bit. You can see the reflection that the sun is emerging from behind the clouds.

The white balance seemed to have shifted too. The colour of the sky and cloud is different.

Can i say it really cuts off a lot of light getting into ur photos in a very bright daylight condition?

And does it cause viggetting? (It seems ur photos have some of it, or just ur touch up?)

:dunno:

The effects from the ND400 looks interesting. :)

Maybe somebody can organise an ND400 outing, to share on what effects can the filter produce. ;)

For those who asked - the ND400 pictures posted are out-of-camera.

For those who want to waste their time picking over the how and the whyfore, the two comparison shots were taken a couple of minutes apart. I have to mount the filter, don't I? And I only had one camera body and one lens with me. And no, why ever will I want to use a CPL with a ND400?!?
(However, if you wish to spare me a pair of S5 Pros, identical lenses, identical tripods and identical Hoya NDx400 filters to do a proper, perfect test for you, please do so.)

The ND400 is, for most people, going to be a novelty filter, just like the R72 IR effects are novelty effects. However, it is, at 77mm diameter, a cheaper "toy" compared to the R72 ($95 vs $165). For myself my 2 ND400s are commercially viable.


Taurean - the kinds of effects is as you can see. Since I am too lazy to spend time postprocessing, I rather shoot out-of-camera.

haha, I didn't notice that the sun was blocked by cloud in the left pic, but right pic got the sun
so actually the light condition already changed, hence cause the NDx400 not 400x anymore
and ya, the wb already shifted and cannot tell the color tone diff is caused by the filter (at least not 100%)
