I have never been a big fan of flash, mostly because I want to learn how to adjust the camera setting to fit the light source I am given. Also, I feel that flash "kills" the scene like deer in the headlight.
In this case, Lola in the headlight.
However, flash can be great when the lighting is poor and your subject is in the move. I learned to adjust the amount of light that emits in the flash. On my Nikon, there is a lightning bolt button left and I press that down along with a plus and minus button on the right side. Meanwhile I adjust the dial on the right side. Lots of fancy finger works.
Here's one with reduced flash light. Not my ideal picture, but it will do for now.
During my visit to Nashville, I experimented with flash on a cloudy day.
With flash and I kind of like this better. The building outlines and color seem to be more defined.
It's still a work in progress for me. Sometimes, I should just try flashing a little...I mean with my camera.
