Nd filters for day shots

[holyxiaoxin]

I'm looking for an ND filter for my lens for day shots. I would like to try blurry waters, and hopefully blurry clouds, if there are fast moving clouds. I plan to take my shots for around 20-30seconds. Any suggestion which stop should i use? I'm considering Hoya.

For a safe bet of having a loooong exposure, you can try 10 stop... *Under some conditions, it can also stretch to minutes...*

That said, what stop ND to use also depends on the lighting condition. For instance, the stops to use for a overcast day vs a cloudless day may vary alot.

For this 10stop ND, you can probably consider the brand Haida in your filter evaluation... The review by one forum member: http://www.clubsnap.com/forums/reviews/1265784-real-life-review-haida-nd-filter.html

I have been using the NDX400 for quite sometime now. It is my favourite filter till date.

take a look at the basic daylight exposure guilde

if you want 30 seconds exposure time

for using 10 stop ND filter, your original day light exposure time should be around 1/15 seconds

for using 6 stops ND filter, your original day light exposure time should be around 1/2 seconds

so a 10 stops ND filter is more suitable.

When you talk about day, I'm not sure what the lighting conditions are like. If it is overcast, then a weaker ND filter would do. If it is bright, then even a 10 stop ND filter may not be enough.

Generally speaking, it would be advisable to get 6/10 stop filter to achieve 20-30 second exposures. Some cameras also have in-camera multi-exposure modes which allow you to layer a number of shots together which will help with the effect. For example, 10 3 second exposures should yield something relatively close to a 30 second exposure, from experience. Of course, layering 10 1/500 second shot will not get you anywhere when it comes to blurring water/clouds.

Hope this helps.

one can try stacking up ND filters to give the required effect, but be careful of the color cast, softness & vignetting as a result, which can be easily corrected in post.

maybe layering 20 shots of 1/500 seconds exposure?

(ought ought ought, heartache of shutter counts, lol)

To get equivalent of 20 second exposure you would have to try 500 x 20 shots actually... That's 10,000 shots... Wonder what will happen in Photoshop. :bsmilie:

Photoshop can always download and install again if you are legitimate user, but the PC probably will up the lorry.

I try to stack 360 layers 12MP tiff files, no problems, try to do auto align, PC crush a couple of them, I let it run over the night and took me a few nights to process what I want.
