B&W 10stop ND Filter (why reddish?)

[darksike]

is it just me or B & W 10 stop filter gives a reddish/magenta tone to any images.

and you don't like that picture? that looks great, it'd even be great in a black and white conversion.

Mine does not produce a cast.
Was this at sunrise or sunset?

[darksike]

thank you. yea I just converted it to black and white and came out great.

at first I thought it was the cokin GND but it's B&W 10stop that's making it.
it's a cool shot but I'd hate to get every single shot that's reddish.
this is from this morning.

the first one was sunset. the one above was sunrise

All B&W 10 stop filters (110) will have a magenta cast. So says B&W (http://www.bpluswfilters.co.uk/index.php?page=products&sec=140). Click the 'Technical' tab for their ND filter transmission curves.

sorry to remain off topic, but that black and white transfer is stellar, i'd print that and hang it.

Okay - color #101
RGB = RED, GREEN, BLUE

Why this order, why not GBR, GRB, or RBG?
Because this is the sensitivity to the film/pixels. REDs are detected and recorded first, then the GREENs, then the BLUEs.

Thus you have a darkened image with primarily RED colors.

BTW - There is absolutely nothing wrong with this shot! Very well done!

Not so neutral then, are they?

So, in order to come out with an image that doesn't have that red tint to it what would you have to do? Just correct it in PP?

[jdizzle]

I guess I haven't experienced the same thing you have with the B+W filter. If it does give off a magenta cast, correcting it in PP will be no problem,

The OP wrote that the 2 images posted were taken at sunrise & sunset.
There is going to be a lot of naturally occurring red/orange going on
at this time of day/night.
Both nice shots by the way.

apologize to bring this back but I'm not too familiar with photoshop. (using CS) and what would be the best way of getting rid of the red cast?

like this image I took yesterday with the sun. I like the color of the sun but not too fond with the clouds.

well I think it is an incredible image.... I think I would die if I took something like that...

EDIT: after playing with it in PS I now see what you mean by the magenta cast...
Is something like this what you are looking for?

Not so neutral then, are they? The problem is that the atmosphere at sunet is filtering out the blue part of the spectrum, just as it filters out (diffracts?) the reds when you have a blue sky at mid day. The filter is as close to neutral as they can get it. The sky has no such restrictions.
