How to Simulate Filters such as the  Neutral Density, a Polarizing and a Gradient Filter.
 
There are good reasons to know how to do this. We can simulate the effect of almost all filters we usually place on the lens of our camera because of the great enhancements made to applying digital filters in post-processing software.
 
I will be using Photoshop for my presentation.
 
Why would we want to use software when we can purchase the desired filter?  The pros for this option is that you are creating the photo on site using only your camera settings. Another reason is that this filter, (as any filter), provides added protection to your expensive lens.
 
Now for the cons. You may not have brought your filter with you or you discover that your filter is not the correct size for the lens you are using. The most important reason is that by adding a filter to any lens, you diminish the optical capability of your lens. How much you degrade it depends on the quality of the filter you are using.
 
In my opinion, it is much better to use software filters than to add a filter to your lens. My tutorial will demonstrate this digital solution and then it is up to you to either purchase a filter or learn how to use the software.
