Neutral Density Filters and Colour Cast comparison
As a Professional Photographer who runs Landscape Photography workshops centred around the use of filters to get the image right in camera I have been getting more and more frustrated with the waiting list for Lee Filters my customers are experiencing so decided to do some digging around the internet to see what alternatives people are recommending.
It now seems common knowledge that Cokin’s “ND” filters give a strong magenta colour cast when layering up the filters, what I was surprised at was that Hitech still seem to be getting good reviews with regards to colour cast. Having moved from Hitech to Lee Filters over 3 years ago I was surprised people are still offering them as a viable alternative to Cokin filters – perhaps I just have a bad set? A series of thumbnails taken yesterday down on a South Coast beach shows immediately how bad my Hitech filters are…
There must be an alternative to Lee Filters, not just cost wise but also the problem with the 6month + waiting list we seem to be currently facing?
I recently had a customer come down to Dorset for a One to One workshop and he bought with him some filters I hadn’t yet seen, although he couldn’t remember the name of them he told me the cost and where he got them from so after seeing his results and lack of colour cast off I went to investigate exactly what and how good these filters are. I found what I think were his filters, Kood are offering packs of 2 “Grey Gradient” filters for £19.99 and 2 “Neutral Density” filters for £19.99 also, certainly you can’t argue with the price… but are they any good?
First look at the Kood filters showed that they were a little blue when compared to the Hitech and Lee filters, although it was hard to get a direct comparison due to Kood supplying their filters in x2 and x4 rather than Lee and Hitech working in 0.3, 0.6 and 0.9. This got a little confusing as the company selling the Koods that I purchased through were advertising the x2 as a one stop filter and the x4 a 2 stop whereas Lee and Hitech say their 0.3 is a One stop and their 0.6 a 2 stop which, in my experience, is very accurate– more on that later.
But photographing filters against a white background isn’t going to tell me how they perform, I needed to get out to a location where I could put them to the test so off I went down to a couple of locations in West Dorset I am using in my new 2012 West Dorset Workshop.
The first location I chose was specifically chosen for its’ simplicity to show the filters in their best light. The beach down at Seatown has beautifully golden pebbles and miles of shoreline where the waves are usually sufficient to give good fluffy water effects. I was shooting about 5pm (a couple of hours before sunset expecting no sunset colour in the sky which could skew the results) so I knew I would be able to get about 1-2 seconds shutter speed with the Lees and the Hitechs and used a 2 stop grad plus a 2 stop and 3 stop ND filter to give me the time I wanted and to show the extent of how my Hitech filters colour cast when layering up the filters… These are the results of the first shot:
Lee Filters Hitech Filters Kood Filters
Wow well what a surprise! I couldn’t get the slow water I wanted with the Koods and even using the “Dark Grey Gradient GG2” filter (which should be a 2 stop) the sky wasn’t as well exposed as the Hitech and Lees (when using 0.6 grads) were showing, BUT, VERY LITTLE colour cast from the Koods when using 3 filters (the GG2 + ND2 + ND4) and the colour cast was only very slightly blue, certainly nowhere near as offensive as the magenta Hitechs!
Onto another location to run the comparison again, this time the cloud was a little lighter but I stuck with the same combination of filters as the sky was still showing 2 stops difference from the foreground so on the Hitechs and Lee Filters I was using a 0.6 + 0.9 ND + 0.6 ND Grad and on the Koods the ND2+ND4+GG2 grad so again trying to push the colour casts you can get when layering up the filters.
Here are the results and again you can see the magenta tint of the Hitechs compared to the beautiful colour the Lee filters give you and the very slight blue tint from the Koods.

About 30 minutes before sunset now and I am hoping I can really slow down the shutter however as always the clouds and sky have a different idea and the sun peeped out between some heavy cloud stopping me from slowing everything down as much as I wanted, however again you can see the difference in colour cast – I’ve added in a Lee 10stop (or Big Stopper) shot into this series, can you see my Big Stopper gives a blue colour cast? I was lucky enough to get one of the early production models and apparently this colour tint has now been corrected.

And finally, the sun has set… The Lee filters are coping well, (although a little under exposed using the same set up as before which I wanted to do so the filters remained constant throughout the comparison and every time I got the sea exposed correctly the sun was too bright – needed a 3 stop but it isn’t about great images – is it?!) The Koods are still doing well although getting frustrated I get can’t more water movement with the combination I have, the Hitechs that allegedly “don’t colour cast” well…

So in conclusion, this hasn’t been written to sing the praises of Lee Filters, we all know how good they are but with the high cost and slow availability issue they are currently facing I wanted to see if there is a more cost effective alternative that produces similar results. The answer I think is YES – the Koods certainly gave some great results compared to the Hitechs and I am now going to find if I can get some darker Kood filters so they can produce the same results I am used to from using my Lee Filters. Well done KOOD!
