Understood. By the way my last entry had a typo. It should have read: "It didn't appear that TTl (with no BL) was achieved."
Following your advice on your blog, I wanted to make the strobe the only lighting. And to eliminate ambient. Somehow that didn't happen. I got spillover (pink) light from another room. And the painting I was shooting didn't convey the rich darker tones in the captured image. Spot metering or CW would have improved the exposure, I think.
By the way, on the SB-800 what is meant when selecting modes the words — TTl-FP — appear in the LCD screen? That's what I was shooting in.
