Half shot? I have no idea what this means. Full shot? I prefer whiskey, when getting a full shot…
I’m going to take a wild guess here that you’re talking about your CU close ups and Medium Close UP (CU and MCU, respectively) shots. When up close and personal, your reflector provides enough bounce to get the light that you want.
However, when you move to the wide, the reflector cannot be positioned closely enough to get bounce while remaining out of shot. Am I close?
If it’s in your shot, no, you really can’t use it, and have to add some units to your kit.
Hard to say what, not knowing the specific situation. Whatever it is should be balanced for daylight (5600), whether natively or with CTB. Each light has a different purpose and flavor, so there is no one answer to this question.
I will say that if you have to battle the sun, highlight your most important dark area with a 2k (there’s a reason I’m not recommending bigger, guys), and grin and bear it. You’re not going to have the resources for an instrument that can compete.
A really spotty unit is going to be the most help in that sort of situation.
