In this case it may be best to use the walls as big reflectors (with your speedlights).
Ideally, you'd be able to get into the rooms before and do a test shoot.
Originally posted by Zafar Iqbal I'd like the ability to shape my light rather than having it bounding all over.
Even when you use walls as reflectors, your light will still be directional. As they will be very large virtual light sources, they probably give you better quality light than any regular sized local source (e.g., softbox) can.
A smaller local source will also spill light and if you need really tight control, you may have to think about using grids, gobos, etc. N.B., I think your softbox is too small for portraits. I'd rather use the reflectors.
Originally posted by Zafar Iqbal The kind of lighting I'm going for - not 100% settled yet but probably a mix between these two:
Note that in the first one there are at least two light sources. You won't get this look with one source unless you are able to use the ambient light to your advantage.
Originally posted by jonby Personally I would either go for the Yongnuo YN560 III/IV plus YN560 TX controller, or the Cactus RF60 plus V6 controller.
I agree these are good suggestions. While the price of the Yongnuo is very tempting, I'd consider the extra functionality the Cactus have to grow into, their reliability, and compatibility with other equipment.
For instance, with V6s you'd be able to remote control your Metz 58AF-2 and they would also play with your existing V5 triggers (with no grouping for the V5, though, as the V5 don't support groups).
BTW, while the RF60 looks similar to your Godox TT660II, the electronics and other innards are different. I believe the TT660II is a manual flash, so its power levels cannot be remote controlled using V6s.
Originally posted by frogoutofwater Strobist.com can give you some good ideas about basic kit parameters.
I agree regarding the principles of equipment choice, but the concrete equipment recommendation section has not been updated in years and hence is outdated.
Originally posted by jonby If you're using speedlights you will need to get a bracket to connect the flashes to a light stand.
The RF60 has an integrated tripod thread, however, yes for using modifiers one would need respective mounting gear.
Originally posted by Zafar Iqbal We will be doing some of the shots outdoors though. Perhaps a mount that can hold multiple flashes would be enough?
Yes, there are mounts that can take 3-4 speedlights. Outdoors, your main problem will be sync speed unless you want to stop down a lot, so either you find an HSS/HyperSync solution or you need to use ND filters.
Originally posted by Zafar Iqbal Maybe even Eye-fi? I have no experience with Eye-fi.
Unfortunately I don't have experience with Eye-Fi cards either. You may want to look at the FluCard as well. In any event, I would probably not attempt to transfer RAW images over WiFi (too slow), so probably you want to shoot RAW+JPEG with the JPEGs being sent to your WiFi-capable card.
Not sure how reliable any cabled solution is. Haven't played with any software except the very outdated camera assist for the K100D, etc.
