For tonights post I am showing you a photograph that I took last summer in the middle of the day in bright sunlight. By stacking Neutral Density filters on top of one another I was able to get the exposure down to 35sec at f22 with 100 ISO. This is a digital photo and I found with longer exposures and more filters I was getting a strange red cast to the photographs.
Let me know your thoughts and if you have ever experimented with this type of filter stacking before.
