"CLS system" is a tautology, "CLS" by itself means "Creative Lighting System"

It's intended use is with the R1 twin-tube macro flash, but it will work with the whole CLS, making the pop-up into a sort of reduced-power SU-800 unit on- or near-axis (with some white light spill, of course). | |

The preflash does happen before the shutter opens, but the control flash can't. But the important thing here is that the commander mode uses a diminished pulse for the control, and while it will show up in reflections, it's intended to be minimal and not contribute to the exposure, as opposed to "master" mode, where the pop-up flash also fires intentionally to light the subject. | |
| Nov 26, 2012 at 20:43 | comment | added | Dan Wolfgang | Yes, the light emitted during preflash is minimal, but it's certainly there: try shooting a highly reflective surface at 1/250 sec/small aperture and you'll have no trouble capturing the preflash emitted in commander mode. | |
| Nov 26, 2012 at 20:11 | comment | added | strobity | I think (perhaps mistakingly) that the pre-flashes used for TTL metering happen before the shutter curtain opens. I guess this is basicaly the question | |
| Nov 26, 2012 at 20:05 | comment | added | mattdm | But, it has a "commander" mode where the emitted light is minimal and intended of communication only, not to contribute to the exposure, right? | |
