In outdoor photography, there are certain lens filters you will find useful. In this video, world- renowned photographer, Ian Plant, shows you why. Ian recommends placing photo filters into a metal filter holder that attaches to your lens. The advantage is you can use multiple filters at once as opposed to stacking the screw-on filters, which can create vignetting. With the filter holder system, you can rotate the holder to optimize the position of the photo filters so you can get the best photograph.
