Use of filters

<p>Can A polarising filter be used on top of a UV filter or vice versa? For digital photography.(Nikon D80 ).<br>

<p>It can. But it may lead to vignetting at the corners, and depending on the situation and the quality of the filter(s) increased flare, ghosts, etc., etc.</p>

<p>The smart thing to do is remove a protective UV filter before adding a polarizer. The lazy thing to do is to just stack the polarizer on top of the UV filter.</p>

<p>There is really no point in putting a UV filter in front of a polarizer.</p>

<p>Yes, but you need to be a little careful about this... and one wonders why you would want to do this.</p>

<p>You can stack filters if necessary. I have done this with a 9-stop ND and a polarizing filter. (Don't ask... :-) Depending upon the filters and the focal length of your lens this may create vignetting if the combined filters extend into the image area. There can also be some concern about reflections and flare when you add more flat layers of glass.</p>

<p>But, why would you combine a polarizer and a UV? I suppose it could make some sense in a way if you are shooting film and perhaps very high altitudes. But there is no reason that I can think of for combining the two filters on a DSLR. The only value of the UV filter is its supposed protective ability - its UV filtering is wasted on DSLRs since they are not sensitive to UV light in the same way that film is. So once you add a CP there is no reason for keeping the UV filter on the lens - the CP provides the same so-called "protection."</p>

<p>Every filter has two air-to-glass surfaces. Each surface is a potential source of image-degrading flare. Fixing flare is Photoshop is difficult. Stacking filters is not recommended, unless absolutely necessary.</p>
