    Default HiTech ND?

    I am looking into ND filters with around 10 stops for long-exposure application.

    The HiTech 3.0ND is a squared filter so it can be really convenient if I would like to stack GND with the ND filter. However, a search on the internet reveals some problems with the HiTech filter, there is a significant magenta cast on the photographs. (Ref: http://mycanoneos5d.blogspot.com/200...d-30-test.html) Does any one have experience with this problem?

    The LEE Big Stopper, which is so far the best according to the review I have read, is way out of my budget at $200. So, any other recommendation? Should I go for the screw in type like B+W ND110 or the HOYA 400X ND?

    Please advise.

    10 stop nd filters, from what i've seen, then to have ir contamination, leading to casts of some form. this is called color shift

    i haven't seen many out of camera results for the big stopper, but i really doubt that it would escape this cast problem.

    the solution is simple - just shoot in raw, and adjust the wb from there.

    even singh-ray isn't free of casts.

    I understand even the best filter is not cast-free. I have read that the colour lost whilst using HiTech filter was so bad that, you can't adjust/fix it.

    The results seems pretty contradicting, although there are signs of magenta cast the one in
    http://mycanoneos5d.bl.....-nd-30-test.html is way worse than the one here http://blog.robertstrachan.com/a....-nd-filter-review/. I suspect that the difference in result in due to the LEE GND which helped to absorbed IR. Different camera seems to have different level of tolerance too.

    HiTech is out for me, having seen various sample, Canon cameras are particularly vulnerable to the colour cast.

    Lee Big stopper costs 188 at CP. But we had to put our names on a waiting lists for pre-order. Tried it. The Big stopper is a lot cooler then the ND110. It is slightly cooler than what my eye perceived to be the actual lighting conditions. but it is very slight. Easily adjustable in custom WB without any color loss.

    Sorry I have not tested the Hitech 3.0. So far the 0.9ND and the GNDs are all color cast free for me. And FYI I am on Nikon system.
