This second test is a bit more "real world" and it shows the ability of the ERQ to actually overpower the daylight at the same time of day. The subject is in the shade of the tree but you can see that the sky, gras and building are all at least one f-stop underexposed. Again this is with the very inefficient shoot through umbrella and the ERQ is 1.2 metres way. The pack is on full power a this stage (400 w/s) and the exposure is 1/180th of a second at f16.
With a decent soft box or with no light modifier I have no doubt that the ERQ can match or overpower daylight under any lighting conditions here in the UK. I'm pretty sure that it could handle all but the very brightest midday light on the equator too.
These are useful tests and I hope that they help answer a few of the questions that I have been getting from people interested in the ERQ system. As an aside I have been looking for a semi-rigid bag for the kit and so far haven't found exactly what I'm looking for. The closest has been a Lightware case but it isn't perfect and so the search goes on!
