These filters are pretty high quality
These filters are pretty high quality. The glass is clear and keeps your images crisp, even if you use multiple filters. I've used a few for setting a specific ambiance in outdoor shots, and the range of graduation works really well for landscapes. You can always add a graduated filter effect in post, but you run the risk of not knowing how your image will look beforehand. If I know I'm going to want to filter out some light or add in some ambiance, I use these filters while shooting. I couldn't be happier with this product and the variety of filters in this kit. I received this product for a fair and honest review.
