Quick shot with my IR camera. I'm not sure if it's the filter, the window or the lens, but the center of this shot is quite sharp and the edges are not. I'll have to do some testing, but I may have to take this lens in to get adjusted.
I started my photo-a-day project on September 6th, 2004 on livejournal, transferred it here around 2011. All photos were taken on the day they're posted...
