You are right Jameel it is a 720nm with BW conversion. It is my favorite method to shoot IR. Thanks for commenting, comments appreciated.I like it. This looks like 720nm with BW conversion.
HI Jim: I have never use the 590nm filter for IR conversion and have only used the 720nm filter. What is the difference andHey Larry,
While I prefer 590nm for my own IR Conversion, I do like the look of the 720nm. You did it really well here.
