I’ve been trying macro photography and using the depth of field to make the subject of my photos stand out more from the background. This photo of a parrotfish shows promising results beyond “blurry fish butt” quality. I’ll definitely use this technique more often in the future, especially for colorful fish with colorful coral in the background.

I’ll be very interested to read about which open source software you use for photo editing. And which steps you take to achieve or enhance the effect described above.
Darktable, shotwell and Gwenview are my tools of choice.
Isn’t macro photography just photography? If macro means stuff that you can see with your bare eyes.
