Magenta color cast help

[Jarrod268]

I used two filters - a B+W 6 stop filter and a Singh-Ray HD grad, .9

I was going for 20-30 second exposures in the morning with water. Inadvertently these all came out with a magenta color cast.

I shot RAW and when I do try other white balance settings, the foreground seems to correct but the sky still has a magenta hue.

Avoid filter stacking? These are not cheap filters.

If you open #1 in an editor, go to Levels, select the Red histo and reduce the right-hand output slider to ~220, the magenta cast is gone.

Thanks! They actually look more interesting with the magenta cast (shows how bad I am!)

Are these better?

Yes I think so. I know what you mean about the magenta though. I wonder what causes that ?

crazy good.

A lot of the ND filters, even expensive ones, are known to have magenta color casts.

 

[Jarrod268]

I think its the combination of both, neither one have this effect on their own.

 

[shufti]

Thanks for that.

Can I ask what you guys thought of these? I know I have some blurred leaves

I like the location but i think the compositions are poor due to the ugly foregrounds. Zoom in..or even go stand in that water, with a tripod to get a better shot. I would. Your portrait format shot looks good. Try taking from a lower POV.

 

[Jarrod268]

Thanks, interesting... The camera was about 2 ft of the ground. I can't get much lower.

This is a class 2 natural area and if you get in the water or off the trails they even threaten to confiscate equipment.

Fair enough!

e.g That twig in the foreground. The closer stump, in the foreground. If 'the hills have eyes', I guess you'll have to do more legwork to find a pristine composition. Looks like you could have just raised the angle of shot, skyward, to exclude that stuff.

 

[Jarrod268]

I agree with you. I would have removed the small stump or moved out father if at all possible. I like some of the rocks in the water though.
