Originally posted by imtheguy I always use iso400 for flash shots at normal indoor ranges. I don't know why except that always seems to work best and maybe I picked it up from using iso400 film for indoor shots.
Thanks, I will check how things are with 400 ISO, but I doubt that this will make big difference (though who knows, it may work for some peculiar reason).
Originally posted by imtheguy I agree, the direct shot is quite different than my results but I use K20D/K5 and do not know our metering settings match (center? matrix?).
For all three samples the metering was set to matrix. Btw. I tried to use center-weighted metering, but it made no difference for the flash exposure. I also tried to bind exposure to the focus point (The focus point was set to the central one). This made no significant difference either.
Originally posted by imtheguy Does pushing the Metz by 0.3-1.0 strength make it better or does the camera adjust the shutter and remain under exposed?
For all three shots I used the same settings. Mode was set to manual, so I was setting shutter speed, aperture and ISO (which were the same for all three shots), leaving for the camera to adjust the flash intensity. As you can see it did quite well with the on-board flash, and not so well with the external Metz 48 AF-1 flash.
The ISO was deliberately set to 200, in order to match my Nikon D70s (which I used for testing as well, and on which ISO200 is the lowest ISO). That said, Nikon D70s exposure of the same scene with on board flash was very similar to the Pentax K-x exposure with on board flash (colors being better on Pentax).
If I set exposure compensation to +0.7 or +1 on the Metz 48, then I can get similar result like from K-x on board flash for this particular scene, i.e. the exposure looks better. It is not consistent however and I cannot leave EV set to +1 on the flash permanently, as for some other shots then I can get slight over-exposure.
