10 stop filter colour cast on 5D
I am trying a Tiffen ND3.0 (about 9 stops I think) on my 5D Mk1 and am getting a colour cast and/or a huge amount of noise on some images. The colour cast is almost a sepia tone and most noticeable on green which is always rendered brown. I bought the Tiffen filter because it had very good review with, apparently, minimal colour alteration. Of course I can correct this in processing but I would rather get it right in-camera. I would welcome any thoughts or comments.All my long exposure images have a 'vintage' appearance at present. Also why are some images coming out so noisy/pixellated?
