For #1 I was on shutter priority at the time focusing on something else, when some rude lady bumped into someone else and just kept walking. The guy was pointing at her. Without thinking too much I just raised my camera and fired.
For #2, yeah the sun was high and harsh, but I definitely should have opened the aperture up more. I did take the f-stop down to 9.0 thinking it would help with the background, but apparently not enough, and I was too worried to go bigger cause of the sun.
The desaturated look is from custom picture styles I created last night. I'm still experimenting with them for now, trying to create an alternative to traditional b&w.
Appreciate the comments.
