Little Blue Heron

Almost adult immature Little Blue Heron, I think.

9/12/17, 5:46:16 PM
Canon EOS 7D Mark II EF100-400mm f/4.5-5.6L IS II USM +1.4x III @401mm
f/8, 1/2500, -0.67, ISO 3200 (big mistake)
Aperture Priority, Evaluative Metering
Imported into LR, processed in CC PS 2017, tiny amount cropped off bottom, small amount cropped off top.

This is in my flooded (thanks to Irma) back yard.  I had room to put a stool out there where the water has receded a bit and try images of some wading birds. 

The water reflected the light, even at 5:46 p.m., so I tried exposure compensation for the first time.

I made a BIG mistake and left the ISO at 3200 from when I was trying some birds in shade/trees.  That's really embarrassing.  It's too easy for me to forget about things when it's been a long time (3 months) since I've been able to do this.

Even so, I didn't have any trouble processing this, starting in Adobe RAW.  I'd like to know what you think about the processing.

With the ISO mistakenly at 3200, I did do light noise reduction on the background even on these small images.

But I do like the image in general, the colors of the water, the bird on the floating grass, and the fact that it was very unusual for this particular bird to come that close to me and basically pay no attention to me, so that's why I'm posting it.

Any feedback would be greatly appreciated.  Please view the "larger" version.  Thank you!
