I haven't shot film in so long, I've forgotten some of the tools and techniques. How would I equip myself, given the Nikon equipment below, for wireless-TTL (IR) control over a given Nikon Speedlight?
1. Nikon N90s 35mm film SLR
2. Nikon SC-17 remote TTL cable
3. Nikon SC-29 remote TTL cable
4. Nikon SU-4 TTL slave
5. Nikon SB-27 Speedlight
6. Nikon SB-800 Speedlight
The only item listed above that I don't own is the SU-4. I would buy one, but I don't know what I'd "command" it with, or how I would control the "primary" flash that it's slaving from. I read that I can use the SB-27 as a commander, but I would have to fire the SB-27's flash head to do it (which I don't want to do). If this is my only route, tell me if the following is correct:
1. Mount SB-27 onto N90s hot shoe, and put SB-27 into commander mode.
2. Attach SU-4 to Nikon Speedlight model(s) _________.
3. Fire away.
I have a ton of old Wein transmitter/receivers, but these won't give me TTL control. Is there any way of using any of Nikon's IR systems to maintain TTL control over a given Nikon Speedlight wirelessly (even if I have to buy a particular "legacy" Speedlight online somewhere)?
Said another way, I want to do the same thing with my N90s film body that I'm doing with a modern DSLR/iTTL set-up: i.e. Nikon D7000/SU-800/SB-800. Basically, I want to have wireless-TTL control over an off-camera flash, WITHOUT having to fire an on-camera (visible) flash for sending "commands."
Thanks for any replies!
