Just replied Gerard. I suggested using a Vivitar 285HV flash instead of the Canon. This way there is one flash.

I'm indeed using digital, and to make things more complex, most of the time I use wireless E-TTL with multiple flashes which rules out using FEL altogether. It seems that manual flash is the only way. I also observed in the images that when ambient light levels where higher, the eye-blinking was reduced. Are there any other alternatives? -greetz, Gerard. ____________________________________________________________________________________Ready for the edge of your seat?
