I'm continuing to play with Adobe Lightroom, and it turns out I've been doing a lot wrong for five years (i.e., since I first started shooting with a digital SLR). It looks like I'm going to shoot a lot more raw photos, because they allow modern software (like Lightbox and Photoshop) a lot more control over the final image.
And, of course, I discovered this using Parker as a subject. The results don't completely suck:
50mm, 1/60 at f/2.0, ISO 3200.
50mm, 1/15 at f/1.8, ISO 3200.
