Very eerie shot - I love it.
One question, did you have your camera sensor altered in anyway (i've seen people post about sending them away to get converted) or is this simply the effect of using the filer and a little b&w coversion in post? If this is just a filter, has anyone tried this on a NEX or a55? I guess the slt might not be ideal due to the mirror but what about the NEX? You've made me curious now
