Diffusion filters in outdoor photos can really add a dreamy romantic mood.  I am never without filters.  As I mentioned before I like to make my own.  Get some clear mylar plastic. Cut pieces that will fit in your lens shade.  You can use a felt marker to add different colors around the hole for some dramatic effects.  For a visual on the home made plastic filter see page bg19.

   See the use of filters such as fog and soft focus as well as how to make your own special filters.  


 
The fastest and easiest way to get this kind of effect is to use fog or soft focus filters.  I prefer the fog.  If you have time and don't mind the mess you can smear Vaseline on a skylight filter and experiment until you get what you like.  Some customers may not like soft focus so I take them both ways.  To see the photo without the filter click the image.
