My thing is, manuals give me tornado brain, as I've stated before. ESPECIALLY Nikon manuals. I am a visual, hands-on learner. When I got my flash, I slapped it on my camera, turned to my husband and said, "SMILE!"...flash did not fire.
I was like, "What the holy hell...?"
So, I grabbed the manual I printed out (my friend couldn't locate the manual for the flash, so I got it with no manual), and...instant tornado brain. My husband found a you tube video on how to set up the SB600 in remote for the D80. Well, I have a D300, but I was able to find the same settings, so I got it working in remote mode.
YAY.
But damn that pop up flash firing. My dog had "green/blue eye bulb" in almost every shot, and my frustration grew. I tried looking in my manual (tornado brain), I tried searching online, I tried asking people. I couldn't find ANYTHING that helped me learn to get it to work ON my camera.
Oh, and don't try changing ANYTHING on your flash when your wide angle reflector thingy is down on it. Won't happen.

See where I'm at with this flash stuff??

My problem was: I kept thinking my changes had to be made in MY CAMERA. So, for whatever reason, it didn't occur to me that I had to change modes on my FLASH. D'oh and DUH.
FINALLY a friend asked me, "Well, what mode is your FLASH in?"
And the bells went off and I grabbed my flash manual, and I FORCED myself to find the VERY simple answer I was looking for.
I got it on TTL, slapped it back on my camera, locked it in place, BAM. My flash fired.
Now I'm afraid to put it into remote mode ever again. ALL I needed to know how to do was how to change modes on my flash. But I'm POSITIVE, I'll have to look that info up AGAIN when I want to change modes.
I'm exhausted.
