Stacking filters

    I'm thinking I was right on the border of exceeding capabilities on a
    recent high altitude shoot. Using a Nikon N90s with circular polarizer
    and an 81B warming filter (sorry, I just can't afford a warming
    polarizer just now), and the lens hood (on a 24-120 Nikon), some shots
    seemed to exhibit a slight vignetting. I am assuming that's due to the
    stacking? Is there a rule of thumb, should I be best off not using the
    hood when I need to stack? All in all, though I still got some very
    nice shots on the trip....

  2. Best bet is to try out the combinations you have on your equipment at
    the zoom you will be using.

    There is a lot of difference in filters, some are thinner than others.
    Some come in both normal and thin versions. Some lens hoods fit the lens
    and are not affected by the filter(s) and some mount on the filter so they
    are affected by the filter(s)

    It would appear that you should not use the hood with the stack at a
    wide angle setting. Then again under some conditions, you might experience
    serious flare and you might be better off eliminating one or more filters
    and stick with the lens hood.

    Sorry there is no single rule.

    So ... post the phots!

    Stacking is a good way to get vignetting at the wide end at large
    apertures.
    In particular if you also had a UV/Skylight filter, plus 81B plus
    the pol it becomes pretty much guaranteed.

    The hood may make it worse if it is pushed out... with my circ
    pol, a threaded hood cannot be used.

    Rule of thumb: if you stack, think about aperture and FL
    contributions to vignetting. Wide aperture and wide FOV will
    vignette many lenses _without_ filters ... adding them just
    increases the liklihood.

    Cheers,
    Alan

    Thanks for the tips, and uh...I feel retarded here...where/how's the
    best to post pix? Use a Yahoo location for them, or some other
    hosting? I haven't posted a lot of stuff on line all these years, ho
    hum....

    I was at Bodie State Park, CA in June. As I said, I think I got some
    very nice shots, especially considering as "everyone comes to Rick's"
    so "everyone photographs Bodie!" *:)

  5. Hi,
    Yahoo or any other place where you can send a web link to the page is
    *the best* way to post stuff.

  6. I believe Nikon lenses are designed such that they may take one filter
    without vignetting. Longer lenses don't vignette as much, but my 28mm
    always vignettes with two filters stacked.
