Here are a few more fin shots.  Both are from yesterday on the Lost.  I have been carrying a Nikon macro 105 2.8 with me on the river in lieu of something wider.  It was a rare day for me as I fished the Wood.  We had cool grey skies and zero wind.  The bugs (baetis) really didn't start where I was until after 2.  Hopefully the Fall baetis gig gets ratcheted up.  We'll see.

Adipose fin from a rainbow.  I get the black background from dialing down the exposure and backlighting the subject.

Brook trout from the Lost River.  This male Brookie was no larger than 10 inches and was in full spawning color and had a very prominent jaw realtive to its overall size.
