Mounting the umbrella accurately is the first thing to set up the lighting effectively. Whether you want a soft light on a large area of your subject or you want to light up a small area, it all depends on mounting.
You can mount umbrellas in two ways. One is with the strobe or flash head and the second one is using the camera flash. In both situations, you have to have a holder for the umbrella. Studio strobes have a small hole and a knob into it to handle the umbrella. All you need to do just insert the umbrella into the hole and tighten it with the knob.
On the other hand, if you use a camera flash you need to buy a flash bracket that has an umbrella holder to hold the umbrella. Just like a strobe, the handle of the umbrella will slide into a small hole on the bracket. It’s got a knob on the side to close it up.
Be careful how close the light is to your parachute. When you place the strobe or flash near the shading, the light is too close to filling the whole shading.
