Great shot Andrew. The IS-1 is a fun tool. I'm loving mine. You maybe interested to know that the cokin red filter works well P003. I just channel swapped the red with blue. I normally use the hoya R72 but light was not so good so i tried the red filter and was plesantly surprised .
I am glad I opened this post as I am not a huge fan of IR but folks like Paul and now you are changing my mind slowly. Very interesting shot I really like it. Lots of feeling ... sad mostly (for me) Is this a crop?
