I have (or soon will have) a G9 in an Ikelite housing with a DS-51 hooked up via TTL sync cord. I also have a YS-90DX TTL Duo that I would like to use in slave (cordless) TTL mode.
The only concern I have is that the YS-90DX manual states that in the cordless TTL mode "the master strobe's guide number must be equal or higher than that of the YS-90DX. (If it is less, the YS-90DX may not yield correct exposure)"
The guide number of the YS-90DX is 22 & for the DS-51 is17. The YS-90DX is reduced to 16 if the diffuser is used.
Am I doomed to having overexposed shots when I use them both in TTL mode?
Can I get around this by using the diffuser on the YS-90 and not the DS-51?
Also the DS-51 puts out 5700 degrees Kelvin light and the YX-90DX is 5100 +/-300 Kelvin with diffuser.
Will that be noticable or be covered up by the fusion of the light?
Thanks!
