hello all,
I recently purchased a Cokin Filter Kit that came with a variety of ND Filters, some graduated ND Filters and some Colour Grad filters. I went to photograph some waterfalls yesterday and put in the 6 stop ND Filter to slow the shutter right down for the silky water effect and all of my images came out Blue... I was on Sunny White balance too??? I thought ND Filters were supposed to be different levels of Grey... so there shouldn't be any blue in them correct? ..... anyone else use Cokin and have the same issues?
Also, if the issue is just the fact that they are cheap crap ND Fliters made incorrectly... which company should I go with that will actually work well for long shutter photography because i plan on doing quite a bit... I know LEE Filters are the best.. but there's no way I can afford to buy those crazy priced things at this stage of the game.
Thanks.

They are indeed cheap crap I fell into the same trap. But mine (not Cokin, but another cheap brand) give a very purple hue, and highly reduce sharpness. It's unfortunate, as I was excited when I got them.
I will let others here recommend better brands. |

Many of my Cokin's from film days still work but the ND range all turned purple/bluish with time. The parent company went into administration in November 2010, and Cokin was rescued by Kenko Tokina Slik in 2011. The Cokin website was off-line for at least a year. It looks like they are back now, and even the Wikipedia page has been shall we say "renewed".
I have a Formatt-HiTech ND Resin Std 100x100mm 0.9 and a few more have my name on them as they are superb and well priced...in the next year |

I have two Tiffin filters (Graduated ND and Circular Polarizer) which were not TOO expensive, and I haven't experienced any color-cast issues ... BUT I have Red/Green color-blindness so I might not notice ...:-(
I don't use either very often. I also bought a second (linear) polarizer ($10 used) which I use together with the other one to make a variable ND filter -- I can get about four stops of exposure compensation that way.
The Tiffin filters are screw-on, so you could have a problem if you have lenses with different diameter threaded ends. They do come in a sturdy case. |
