Moonlight strobes have a limit for their power due to their size.
when shooting outside, use a high-powered strobe to overcome the natural sunlight.
Most lights, regardless of the brand or model, provide heads that come in the form of a strobe surrounded by a reflector.
Reflecting umbrellas produce a diffused and soft light due to the larger size of the reflecting surface. They are mounted in such a way that the strobe light is actually facing away from the subject or model.
Silver-lined umbrellas are the most efficient and can focus light more narrowly than the other types. White umbrellas offer a wider spread of reflected light, and gold umbrellas produce a warm tone.
Light emitted from the strobe head gets reflected inside the walls of the soft box and diffused through the box’s translucent front creating a soft, but more focused light source illuminating the model or scene.
With an umbrella on the other hand, light can spill beyond the boundaries of the reflective surface affecting the amount of light getting back to the subject. Spilled light can also hit walls and ceilings indoors causing it to reflect and bounce all over the place. An umbrella simply isn’t as controllable as a soft box.
Snoots are conical shaped tools that narrow the distribution of light, they are often used like a spotlight or to light the background.
Barn doors are flaps surrounding a strobe that can be opened or closed to control the light and prevent it from spilling.
Flags are another type of light modifiers. A flag is any kind of opaque object placed in the way of light to better direct it, to prevent lens flare or to prevent it from spilling.
