I use a 43" or so umbrella when taking photos on location, but after buying more than one modifier (softbox also), I'm finding it's almost impractical to use most of the time because i don't shoot models. These are freinds, and they want a photo NOW.    It takes time to set it up even just a few minutes. I know my stuff when it comes to using soft light, but they look at me like Awww, you don't need that, just take the photo.     So, even though i bring it, half the time I'm using a bare flash on the stand to save time. But also because alot of time their are alot of "spectators" around, and i don't feel comfortable setting up this stuff in congested public areas.   I have read and watched so many videos how everyone does it, but this is something i don't understand. Maybe most of them, are shooting ONE model with no time restraints and also, in more secluded places.
