Greka,
As I undestood it, Evrim is talking about triggering studio flashes with the
built-in flash on the EOS 50E. (Some/most/several??) studio strobes have slaves
to trigger each other in a multi-flash setup, so you (usually) connect your sync
lead to one of them and the rest follows. You can use this slave functionality
to trigger them with a built-in flash as well. And as I explained before, they
are responsive to the IR output, so covering the body flash with a IR filter
will help further in eliminating the influence of the built-in flash output on
the final image. Negative exposure compensation should do fine, but sometimes
(depending on the power of your strobes, f/stop , film rating and lighting
setup) it can be intrusive.
You're right if the 'slaves' we're talking about were TTL slaves (like the
ikelite)
Greetings,
Gerard.
