I need some help with Flash setting... Generally Where are the areas that Minolt's TTL meters the flash? Sometimes I get blown out pics especially when there's a lot of empty space behind the subjects... So when do I compensate the flash? With wide angle shots where the subjects are at different distance to each other, other than bouncing, will a diffuser help? After reading about Canon's fill-flash mode... I'm quite happy minolta did it the minolta way~

The problem with the situations you are describing is that the background is very dark, hence fooling the flash into pumping out a lot of light and washing out your subjects in the foreground. The issue is that even though it looks bright, say under normal indoor flourescent lighting, in reality it is a few hundred times dimmer than it is outdoors. This really is an electronic issue for the Minolta engineers to work out. As for what areas are metered, that should be stated in your camera manual, if not chances are it is exactly the same way your normal metering works.

Short of setting the flash to manual and working with GN, aperture and distance, there's not a lot you can do. Alternatively, eyeball the situation and dial in flash compensation.

Ninelives... that is why I wished I have more manual controls...

So how does the flash's zoom works? Will mannually adjusting the flash zoom helps?

The flash's zoom head adjusts the angle of flash coverage, narrowing it to concentrate the light and deliver more effective power when you are shooting with lenses with narrower angle of views. It has no impact on metering.

How come I never get these problems when I am using the 3D Multi-sensor balanced fill flash of a certain camera maker? ;p :rbounce:

Solution : Don't leave everything on auto. If you are syncing at 1/250 for example, drop it all the way down to 1/60. 1/30 if you are confident of hand holding it at your chosen focal length. Open up the aperture a bit more. Use a higher ISO. As long as the ambient exposure is not more than 2 stops dimmer than your flash exposure, you're fine.

Using bounced flash helps too.

because Flare is not using ADI lens with ADI flash. ADI is like Nikon 3D metering. ;p

Yah... I think D5's ADI not the best.... And I usually have the problem when the ambient light is less than 2 stops below the flash.... Seriously... what should I do when the ambient light is more than 2 stops below hand-holdable shutter speed even with aperture wide open??

Increase ISO, your only choice.

The adi function on Minolta 7 and 5 work only when you use the new D lenses. Basically ADI measures the flash to film distance and exposes accordingly. Thereofre it is not fooled by reflections etc. The 2 new flashes 3600hs and 5600hss have the ADI functions.
