One filter. B+W I would say is your best bet.....Not cheap though!

You can get a 3 filter set, 2 x 4 and a 1 x 2 ND but as Robbo said, not cheap.

The other option is the Lee 'Big Stopper'. It's a bit cheaper but you have to have the Lee adaptor and holder which will bump up the price.

Or search on here for the 'Welding Glass' filter thread...

I've got the B+W 10-stop but Im now getting rid of it since it gives a very strong magenta/red colour cast that is hard to remove in post processing. Im getting the lee 10 stop hoping it wont give any colour cast, I already have the lee 0.9 ND which is great peice of glass

. Hope this helps a little in making a decision on the best brand.

Please forgive me if I'm teaching you to suck eggs here, but is it possible that you were using the camera without the eye-piece covered on these long exposures :shrug:? I only ask because for the first couple of outings with my 10-stopper, I kept getting this purple 'mist' around the centre of the images. I thought at first that it was a colour cast from the filter, but once I started using the shutter blind, it disappeared completely :naughty:

.

Just a thought!?

I'll have to try that next time I use my B&W 10 stop. I have noticed the colour cast at times but at others not. I did this panoramic with my 10 stop and had no colour cast issues but have some single frame shots taken at other locations which show a strong cast.

Hope the shutter blind solves it

It's generally only a problem if you're in daylight, or if you have a strong light source behind you (like the Sun :naughty:

). If the sun is in front of you and the exposure is a matter of seconds and not minutes, then you won't always see this effect.

Still, I would advocate using the shutter blind at all times, just to be sure. When you're making a 4 minute exposure of the last rays of a sunset, you only get one chance per 24 hours (and often only a couple of times a week, with our weather

). Waiting 4 minutes, only to find that you have a huge purple smear across the middle of your picture is not one of the most rewarding experiences that a landscape togger can have

The B+W is a little warm in colour. I've compared it to the Lee Big Stopper and that is fractionally bluish (hardly noticeable). Lee admit to this, but it is less blue than the B+W is orange. If accurate colour is essential, you will need to do a custom white balance with either of them. Maybe you have a poor sample of the B+W - they do vary in density slightly, so maybe in colour also?

The most neutral dark ND I've tried is the Light Craft Fader. They have an improved MkII version coming any day now, which I have on order, and that looks very promising. They also do a 9-stops X500 multicoated in 77mm only (which I haven't tried) but that is also out of stock ATM (from Premier Ink http://www.premier-ink.co.uk/advanc...ription=1&keywords=light+craft+77mm&x=48&y=10 ). Hoya make a 9-stops X400 which is special order only, is coated, a bit expensive and also a bit warm so I've heard.

For anybody that already has a Lee filter system, I think the Big Stopper is the best bet. It a good filter and I like the way it slips in with that neat gasket, or clips on with the mount.

On the covering the viewfinder eyepiece thing, yes definitely do it always. On the three cameras I've tried, my Canon 350D got a grey fog through the eyepiece, 40D produced a rather attractive rainbow/sunset look in the top of the frame

while my 5D2 seems to be pretty well sealed, but I'm taking no chances - that's what the eyepiece cover is for after all.
