You guys are so cute, talking about "dialling" this and that when you really mean "pushing buttons, reading LCD screens, more buttons, more screens, maybe if you're lucky you'll set up a dial on the back of your camera to "dial" a setting.. But I hear your pain, that you really want to dial.. to have one simple control. Or maybe a few simple controls.
Quantum can be as complicated or as simple as you like. An entire wedding can easily be shot by selecting a reflector for the desired type of flash (taking it on/off quickly also gives you bare bulb which can be great), putting it in either ETTL or manual (after some practice manual is nearly as quick as ETTL) and then fine turning the light by turning this dial up/down either in wireless (if your assistants are in portable light stand mode), or wired (if speed isi essential) with one simple control.
Walking into the reception with your lights already set up and use this control to adjust light output, which lights/banks you want used.. and you still haven't touched a button or had to read an LCD screen. Just shoot and chimp occasionally..
Or use 1-many of these lights like you would studio strobes with nearly the power.. Adjust each light with a dial. Use one light in manual, another in fill, and yet another in some other mode.
It's a system meant for pros in that it can be configured in a simple mode to a highly complex mode from 1 to unlimited lights.. Once you experience the power, the ability to shoot non-stop, to carry a complete system say 3-4 lights in one small bag, the carry out very technical tasks, but mostly the wonderful quality of light on par with strobes.. you'll never play with the toy speedlights again.. It will be an important day in your life..
Watching their tutorials is worth your time many times over.
