The Glow 3 Classic White Umbrella 60" gives an even, diffused lighting effect with soft shadow definition. You can easily acheive 'Rembrandt' light by using two white umbrellas placed as main and fill with any light source, flash or continuous, large strobe heads or portable speedlights, with appropriate stand holders. The absolute standard in soft portable light modifiers.
Glow 3 Umbrellas are the direct fastpath' to light diffusion. Each size and material has a function. With much attention to detail from fabric to frame ribs, this umbrella sets a new high standard for portable light controlfor people and subjects at fantastic value.
The Silver Umbrella provides stronger focused lighting, along with soft shadow definition. It is especially suitable for higher light output, greater reach andbringing out details.
The Translucent Umbrella provides diffused lighting around a bright Central burst. The lighting and effect can be varied by changing the distance from flashhead to umbrella.
Umbrellas are like large to giant sized parabolic reflector. Parabolas are technically 'conic sections'. Take a perfect cone; slice through it down to the base, the edge of the cut is a parabola. This shape is more efficient at feathering light.
The important point of the physics of photographically regarding parabolas is they have a focal point. Place light aimed at the focal point and it bounces off theentire umbrella surface at different angles, but when it leaves the umbrella, all the rays are parallel. A great umbrella design, more light reaches the subject. More control. As a comparison, Glow soft boxes were designed to simulate window, light, sky light and north light. Umbrellas can be more compact and quicker to setup than the light bank counterpart.
Another factor in choosing light modifiers: the shape of catch lights in a portrait subject's eyes and the size of the modifier in relation to the size of the subject. The larger and closer the light is to the subject, the softer the results will be as to the transition of the highlight into the shadow. The smaller the size of the unit and the further the distance is from the light to the subject, the harder the effect will be.
The great value of Glow Umbrella, Softboxes and related light modifiers makes your choice simple - both!
