Hi,
Recently I decided to make use of my AF500FTZ as a "studio" flash. I want to
take a few shots of my wife. I plan to set up the lighting as following:
- the AF500FTZ mounted on a tripod, in the Manual and Slave modes, its head
turned backwards firing into a silver umbrella - all on one side of the
model
- the Sunpack MZ440AF mounted on my Z-1p in of course the TTL (what else:))
mode, its head up bouncing the light from the ceiling
- a small silver reflector on the other side of the model
- the distance between the model and the AF500FTZ set-up is about 2 m, which
means that the appropriate flash settings (according to the manual and my
calculations) are: 1/4 of power, zoom at 28mm
- the film will be B/W
My questions are:
- how big is the light loss due to bouncing the light off the umbrella? how
much more should I open the aperture - 1/2 stop. 1 stop, more?
- how can the flash from the AF500FTZ affect the camera TTL-flash metering
of the burst from the Sunpack? I presume that it may fool the camera making
it underexpose its metering but I want the Pentax flash to be the key light
and the Sunpack to fill the shadows and maybe bounce a little of light off
the ceiling onto the models hair...
TIA
Regards
Artur
