Well after shooting this early afternoon I came back home and started looking at the photos. Wow I was all over the place, kind of frustrating~.
As I keep shooting and reading your posts I started to keep track of what I was doing. Some things started to come in to shape, now, I'm nowhere near to even being ok, but it's a learning experience.
I shoot many without flash and I can see how metering for the face and let the background do its thing helps to make good photos. Most of those where at f4 and /320 or less and ISO 200. They workout but I also want to learn about mixing flash and ambient light.
In the shadow,
For mixing light I was metering the background at /2000 or more. I tried to use TTL and TTL-BL but those settings seems to work base on if i'm doing pattern metering or spot metering so they were not giving steady results. So I switch to manual.
In manual mode pretty much I had to leave it at 1/1 power. If I shoot close up to the face it would work somewhat since I was still not getting steady results but more steady than before. If I wanted to do a full-body shot it felt that at /2000 or faster the SB-600 was not powerful enough.
In the open with sun behind was another whole issue. I don't know where is the correct place to meter. I meter in the background too? That would due extremely fast shutter.
I'm now watching a video in YouTube and the guy says that in the middle of the day I should better use reflector and leave the flash for later in the day.
If you could shed more of your experience and knowledge on this, I would appreciated it. Thanks.
