Hello. Firstly, great shot! I'd like to buy a Hoya R72 to make infrared shots too with my D90, but it has a strong IR filter so...i don't know if it'll work because of this. So I'd like to know if you had your IR filter removed in your D90 to be able to take this or if you didn't need to make any changes. thanks for helping! And what infrared lens do you use?
