Filters are often one of the most under used and simple ways to dramatically improve your photography.
In this case the results are not overly dramatic but you can clearly see the results of the filter in action. Not only have you used a filter, which is really the only requirement of this lesson but you chosen to use the filter for the right application. So hats off to you, you've done well here. Take note of the improved contrast and the lack of haze.
Try to continue playing around with filters. Filters are often forgotten but they can really make a difference in the quality of your images.
High quality filters are often expensive but you can always get used filters and your local camera shop or on ebay.
Filters are now in your toolkit and you've moved up a notch with your photography skills.
