Sometimes you just don't have a choice about the light. The woman wanted me to get photos of her fishnets, right then and there. I grabbed my camera out of the car and did what I could. Sometimes I get to work with the light, sometimes I have to fight in into submission. I suppose I could have grabbed the flash as well, but that would have been even more work. I didn't expect it to correct nearly as well as it did. > > G > > On Tue, Apr 10, 2012 at 6:23 AM, Bruce Walker <[email protected]> wrote: >> Explain to me this, Larry.
