I recently took a picture of Hartebeespoort Dam.It has been printed on the front page of a Tourism Guide Booklet.I didn't receive money for the picture.I just got some exposure.As you can see Underneath the words What to do -Restaurants & Pubs - Accommodation is written Dam Photo Courtesy of Christo Meintjes. Well that is me.I also used a special setting taking this picture as i took it at 2 o'clock in the afternoon.The water is supposed to have a silver shining color as the sun is shining on the water.I do not have a polarizing filter and do not plan to buy one.I read up on the internet a while back when you have the conditions as i discussed here one can set ones White Balance to Tungsten.It gives the wonderful blue color in a picture as i did achieve this result here.Someone else also posted a picture with such Blue effect.Cannot remember who posted the picture.This is the result which can be achieved without using a polarizing filter.
