IBJJF has a great crew of independent photographers who are running around snapping pictures during all of their events! I’ve purchased a few prints myself, and here is some of their work! Oh, and folks, bad taste to remove or crop watermarks/stamps. Unless you purchase the rights to photos, you do not own them or have manipulation rights to them!
That said, here are the pictures I’ve collected (complete with whatever credit stamps were on them!) I tried to group them together, but can’t promise any real order.
