Whilst out for a “boat ride,” also known as fishin’ and ain’t catchin’, I broke out the macro lens to see what I could see. In hindsight I think should have stopped it down to 2.8 to get a little more of the fly.
I shot it wide open at f2.0 to get the good bokeh is why I considered 2.8. It might have haven needed a little more than 2.8 to get all the fly, especially the nice grizzly hackle feathers that are part of the tail but I’m afraid that f22 would have been too much. I should have kept that composure and stopped it down at different apertures and shot and then picked the best one of later. Thinking about it now, I focused on aperture and low ISO too much and could have fiddled with the aperture AND exposure and still kept the low ISO. I’m very much the novice and I appreciate all the advice and kind words.
Yes, shooting a few at different apertures will give you more options later. But, all-in-all, you got a good one already. (I can usually find something that I really don't like about all my images - I guess that gives me reasons to keep trying!).
