does ND filter alter effects of yellow filter?

[Voyager]

I'd been using a yellow filter for some B&W landscapes which involved a fairly bright sky with nice clouds, and a more subdued foreground. Heading home, it occurred to me that I should have mounted my 1/2 ND over the yellow filter to better expose for the shadow without blowing out the sky, but then I wondered whether the neutral density half of the filter would have affected the sky/cloud effects of the yellow filter. Thoughts?

You can use a yellow filter and ND grad (I assume you mean a grad) at the same time. The effect will be different, because the exposure range is different, but the yellow filter still acts in the same way.

Another trick is to use a tobacco grad with B&W. It will increase contast in the sky without changing the foreground. Other color grads work this way too--totally cheesy for color, but interesting for B&W sometimes.

The yellow filter predominately effects exposure of blue areas (like sky) although it has minor effect on each end because the transmission cut off isn't sharp. It has a heel and a toe for lack of a better explanation. The ND filter affects the over all exposure (no heel or toe as far as color goes, if its a good filter). If the filter factors are observed you can use them both, and the ND won't change the altered "contrast" of the sky/clouds (or other blue vs .whatever stuff) provided by a yellow or red filter, only the overall exposure.

If you really wanted to get picky, ND does have a slight cyan bias. Maybe .25c so, "yes" but negligible.

If you want to get really really picky, the bias will increase with density.

Good...the image is affected either none or very little...thanks all....
