It was around the time of this session that I discovered I had my aperture setting at 5.0 instead of the usual wide open 2.8. Once I noticed it I let it go interested in what I'd see. I guess this is much closer to the lens sweet spot and although you lose some depth of field you gain some sharpness and detail. I think it's a good trade off. I prefer the serendipity from learning hands on over reading technical books... What I learn seems to be more vivid and sticks with me better.
