Wanting an ND filter (kit)
 

I'm wanting to try my hand at using ND filters.
Premier Ink have a Kood P-Type ND Filter kit for sale.

The kit comprises of the following:[LIST][*]1 x P-Type ND2 Filter[*] 1 x P-Type ND2 Soft Graduated Filter[*] 1 x P-Type ND4 Filter[*] 1 x P-Type ND4 Soft Graduated Filter[*] 1 x P-Type Filter Holder[*] 1 x P-Type 58mm Adapter Ring[/LIST]
Would this be ok for taking waterfalls and the sea?

I'm also thinking about buying a 10-stop filter, but should I buy both the Soft Grad and the normal filter, or just one of them?

Thanks in advance

Waterfalls and the sea......... yes, though to get those really flat seas and milky waterfalls you may need both the ND2 and ND4 at the same time - basically giving you a 'loss' of six stops to your 'normal' EV. You'll also need a small aperture, like f/22. e.g. if you're getting a meter reading of 1/8th at f/22 without filter, the two ND filters will force you to use a shutter speed of six stops slower - 4 full seconds. Plenty of flexibility to make the milky waterfall but still not enough to give the really flat, white sea. That's why the people who make those shots tend to choose later parts of the day, when it's overcast or even getting past sunset....... they're looking for about 30 seconds and they're the ones that really need the 10-stop ND filters. For most people, the 2-stop and 4-stop filters are fine. By the way, some camera meters really don't handle the huge loss of light through the lens very well - and in that case a shutter speed has to be calculated and manually set. Long shutter speeds can also cause extra digital noise as the sensor can get a little over-active.

The Grad filters are a different case......... they are used to darken areas of a shot that would otherwise over-expose or lose detail in the highlights.

The Kood set should be a good starting point for you.

Thank you for your reply.

Any others would be of great help :)

I have a combination of kood and cokin filters, TBH for what I use them for they are fine although you can get colour casts especially when stacking them but this can be corrected in RAW editting software.

They are as Geoff said a good starting point and a setup can be bought for less than £100 where as with high quality filters such as Lee you will run into hundreds of pounds.

When using the P type adaptor you may get vignetting at the wide end of the lenses so you may also want to get the wide angle adaptor.

I can recommend Formatt/HiTech filters. I have the Z size and hardware from them. I also have their pro-grade 10 stop. All are very good.

If I bought the [I]Kood P-Type ND Filter kit[/I], could I use a 10-stop filter with it? And where could I buy one from?

Also what size are the filters that fit the P-type filter holder?

If I used the filters on my Sigma 10-20mm lens (which I still need to get sorted!) would I be able to use the filters, providing I purchase an adapter ring?

85mm x 85mm is the size, you can buy hitech filters that will fit a standard PType holder, a 10 stop is £60 + Postage here is the [url=http://www.formatt.co.uk/stills-filters/filters/standard-n-d/pro-stop.aspx]link[/url]

Yes you can use it with your sigma but you would need the wide angle adaptor.

Many thanks for your replies :)

This, of course, means that you can use the pro stop with the Kood kit, provided you buy another filter holder. Which means you won't be using any part of the Kood kit. :D

Its out of my budget, so I won't be buying the Hitech
