Yes. I will post some shots. Lots of noise in the shadows tho.
(The Nikon SB-24 Flash I was going to add as the 2nd light is now not working. All flash menus work but the "Sufficient Power" light doesnt come on to even fire a test. It was fine the other day... Changed to fresh batteries too... WTF?)
I will try it on my old Nikon 8008 film slr...

What kind of exposure settings are you using? What ISO setting?

I have 1 flash on a tripod working. My other Nikon Sb-24 seems to have died.
This post and pic explains what I was trying to do.

I had some luck with shooting in overcast and tree shadows with the flash but not with the above setup. Any ideas?

Are you saying that it works well "in overcast and tree shadows" but doens't work in bight sun?

If so, it may be that your flash just isn't powerful enough.
When shooting in bright sunlight, you need to prevent over exposure by using either a fast shutter speed or a small aperture. When using flash, you can't use a faster shutter speed than the max sync speed, so you have to use a small aperture. The size of the aperture is directly related to the flash exposure...so if you have to shoot at F16, you flash may only have enough power to exposure the subject from 5 feet away (for example).

Or...an ND filter???
Did you look at the link and see the problem?

An ND filter won't help because it reduces ambient (sun) and flash exposure equally. A split/grad filter might have worked, if used to cover the girl.

The problem with the girl and the Caddy appears to be that while the car looks OK in the sunlight, that same light causes the girl to be both overexposed (hot spots) and underexposed (shadows). They attempted to use flash it fill in the shadows on the girl, but it doesn't appear that there was enough flash power...or not enough flash spread (not to mention the shadow from the car).

Im confused. How would MORE flash power prevent the blown out highlights on the model (Amy)? (the camera meter was on "pattern" matrix)
