When sitting outside and enjoying our yard, I spent the summer looking at this clump of ferns surrounding the double trunk of a hemlock.  Back then, the ferns were of course green. As they changed color to yellow the light seemed to make them "pop" against the green and darker background.

I further darkened and softened the background by surrounding the ferns with an oval, using the radial tool in Lightroom.  Then I darkened and softened (decreased sharpening and texture, and increased noise reduction) the area outside of the oval, to draw attention to the main subject.

Today, a week after I took this photo, the ferns are brown and shriveled up, having been beaten down by the season and the rain. I'm glad I didn't wait any longer to grab my camera and take a shot.

OLYMPUS DIGITAL CAMERA "Fall Ferns"
October 3, 2020
Olympus E-M1
Olympus 12-100mm @ 100mm (200mm equivalent)
F5.6 - 1/200sec - ISO1000

Given another chance, I think I'd use F4 and 1/100sec.  This would
allow me to decrease the ISO to about 250. 
On the other hand ISO 1000 is not particularly objectionable to me.
