I have been doing some high key shoots with white seamless and three Photogenic monolights,
my main (f/8.5) has a large softbox, positioned/angled close and left to my subject (child),
my fill (f/11) is umbrella-bounced, positioned just behind camera/slightly right,
and my backlight (f/22) has one of those dome-thingys so all the light pours over the background.
Silver reflector positioned at subject's right.

The last time I set this up, my background was blown-out, as I had intended, and the fill was spot on. Yesterdays work had shadows.... and I'm not understanding why I'm not consistent.

So, what's wrong? Are my f/stops off? Any advice.

Thank you --
