I can't believe the lengths some people will go to in order to get closer to a Loon for a picture! I would think that if the Loon becomes agitated, it wouldn't be a very good picture anyway, right? Then the Loon would probably dive and swim away...
With the few Loon pics I have captured, I have been lucky enough to have been sitting on the dock when they come by. I usually will go out in the early AM, with my camera in hand, and just sit at the end of the dock - taking in the beautiful scenery and taking pictures (and I always hope a Loon will come by).
Last summer, one popped up right next to me: I had seen the loon a little ways down the shoreline, sat and waited for him to (hopefully) come closer, then I saw him swimming under the water, comming up right next to me! Of course, I'm trying to be as still as I can and slowly trying to raise my camera for a picture, but he swam away too quick - I still got a pretty close pic though!

And this year, just 2 weeks ago, there was one floating around about 30 feet off the end of the dock, zoomed in and got a good pic with his wings out, but he must have been just "airing out" ? because he didn't fly off - he ended up hanging around a bit, then diving under eventually...

I just couldn't imagine "chasing" a Loon or in any way agitating one just to get a picture!
