10 stop filters and blue cast

I was just wondering -

i understood from a source that as the various ND numbers go up - the chance of a color cast grows. In the case of the big stopper - the known bluish cast.

I think it was also mentioned that adding an IR filter can counter such a color cast (to a point I would guess)

so has anyone tried stacking a big stopper (or similar 8-10 stop ND filters) and a different filter which includes IR filtering? Would that result in a neutral color cast? or at least LESS of one?

thanks for participating in my thought experiment...

Colour casts for high-density ND filters varies quite a bit. I have filters that produce a cool (blue) colour and others that produce a warm (orange) cast. The more you pay for a 10-stopper the less likely you are to suffer problems.

Using a filter that removes IR is unlikely to help a lot. My advice would be to read reviews and look at example images. Only the really cheap and nasty NDs are likely to produce a colour cast that isn't easy to fix in post-processing, if required.

Heliopan -

OP - did you know ND filters are being manufactured with IR filters built-in?

Hitech makes one and claims to be the most neutral 10 stop filter available. And it's cheaper than the Big Stopper.

sorry - i didn't get back to this thread earlier.

Hollis - thanks for the examples. it helps put some things in perspective. I have yet, however, to decide which casting I like better. I suppose that it would also depend on the colors of the subject/background/for​eground and what I have learned to fix in photoshop!

v35skyline: yes, I noticed it. (i started the thread you linked to).... but again I am trying to get a handle on the various non-Lee options since it seems that many of the threads and recommendations are Lee-"heavy".

I corresponded with 2filter.com and I am considering the platinum IRND versions of the Schneider plates (4mm thickness BTW). The "problem" is that they have a 7 stop ND max. Is that enough for me instead of a 10 stop? I honestly don't know. Stacking filters would most likely buy me a problem with light leak. Or adding a 2mm big stopper....for the extra 3 stops in one plate.

anyway, thanks for your input.

Singh Ray just came out with their Mor-Slow 10 and 15 stop filters. They claim that their filter has far less of a color cast than the Lee, but it ain't cheap. Personally I've found that their filters tend to warm the scene a wee bit, but nothing that isn't easily fixed.

thanks for the heads up - I always considered them for their reverse GND - but that 15 stop is sweet! though almost $600 for the 100X100 is a bit pricey, though doable. I am just not sure if there is enough time in day to delay a pic by 15 stops!!!

There certainly is, trust me. I've been contemplating the 15stop myself, though mostly for touristy areas.

This one was with about 12stops of ND, came out to about 4 minutes. . .
