Hi Alex, I think the highlights in the first image are blown out a bit too much. Without wanting to sound too critical, I've noticed that in a number of your portaits and fashion shots with flash you've been getting blown highlights. This may be the effect you are after, but I'm not sure. In the second image, the flash is not as obvious but it's still apparent.
With these type of outdoor shots where, I asume, you are using the SB800 for fill flash in TTL BL
mode, I'm suprised that you're getting the blown highlights. I've found it's almost impossible to blow highlights in TTL BL
mode even if I wanted too. With the d70 in either A or S
mode, the camera seems to work really well with the SB800 in TTL BL.
Maybe you are using TTL
mode where the flash is providing a greater proportion of the light? Are you using a diffuser? I've found this helps soften the SB800's light. Are you using centre weighted metering and metering on her face? I find that works best with TTL BL. I think the full 3D matrix metering or whatever it's called would pick up a lot of the shadows in this image and could cause over exposure of her face.
Spot metering won't work at all in TTL BL
mode, or more correctly the SB800 will switch from TTL BL into TTL
mode if you have spot metering turned on on the d70. Again, even if this is the case, if you're spot metering on her face, the SB800 should get it right.
Please don't take this the wrong way as I'm not having a go at you. I just think that the SB800 is such a great piece of equipment, the exposures should be spot on and I'm just trying to understand what's happening with your use of flash.
Cheers
John
