This is probably the most fun filter I own. I can choose to make trees pink or foliage white, depending; and it's an incredibly easy process! I have to say though, it takes a bit to learn how to focus first and mount the filter second, but it's worth it! Great buy!
I used the product with a Fuji Pro S3 and Nikon Lenses... this filter works with slightly less dramatic effect (which I find more pleasing) than I received with B+W infrared filters on other Nikon Products.
