There's nothing like learning by trial and error. But nothing speeds up the learning process more than having a great resource, and what's been a HUGE resource for me over the last few days is Laurence Kim's blog: http://www.laurencekimblog.com/index.php. He covers everything from gear to tutorials and shares settings and tips that come from years of practice and loads of talent. I feel like I've learned more about photography since Natalie sent me a link to his blog than I had in the last 4 years.
First, check it out for ourself, it's pretty incredible how helpful it is. Second, one of his tutorials shows the different methods of bouncing an on-camera flash and another outlines his settings for shooting studio portraits. Combining these two was the photo I took below.
I bounced the the flash camera right and completely backwards--something I'd never thought to try. Also, I modified his recommended settings (full manual, f8.0, 1/250, ISO 100) to 1/160 and f5.6 (which tends to be the sharpest for Four Thirds lenses--and also explains why it helped the photo I posted as the 1st sign).
Olympus E-620 with 14-54mm @ f5.6. I shot it in our bathroom to use the narrow walls and lower ceiling for bouncing the flash, plus the white wall for a backdrop.
