Both are more than 'acceptable' to me, but I do prefer 'unmanipulated'
outdoor scenes. So I would prefer the latest version, without the magenta
cast. But having said that, without knowing the issue with the filters, I
could easily assume the magenta cast, was what you saw as you tripped the
shutter.

Subject: PESOs - Cauldron - Getting Rid of a Magenta Colour Cast
G'day all
First, thanks for the comments on Cauldron - Jack, Mark, Walt, Bob,
Paul, Ken. Much appreciated.
As I mentioned in that post, I took a number of similar shots, some of
which showed a strong magenta colour cast due to the use of a cheap ND
filter. Here's a fairly dramatic example (30 second exposure, f22, ISO
100, 3 stacked ND filters):

First lesson learned - don't use cheap ND filters.
Anyway, as an exercise I thought I'd have a go at reducing the effect of
the cast. This is what I came up with:

It's certainly an improvement but I'd be interested in any comments on
how it compares with the original 'Cauldron' post:
