Kyrie learned how to turn the camera to "portrait" mode and how to set the 10-second timer. I learned that from the desk to the wall was too far for the camera to get a good focus in portrait mode. And I learned that I need to find a more systematic way to experiment with aperture, shutter, iso, etc. settings, because all such attempts produced failures.
There is definite room for improvement here: that blemish on the wall behind me, my fat arm in the foreground, my possibly-overdone smile, and my acne. We'll find out if I learn enough in the next 30 days to produce significantly better results.
