How we shape light?
This entry will be focused on the quality of light and for that we will start by talking about the types of light:
On the one hand, we have the hard light, which is the one that directly affects the subject or object and therefore as it is direct it has two basic characteristics such as: highlighting the details of the subject/object, and generating marked shadows.
On the other hand, we have the diffused light: in this type there is an accessory between the light source and the subject or object, which makes the latter receive a softer and more diffused light, since by placing diffusers - which we will talk about next - between both, the light source loses intensity. With respect to the shadows, they are less marked and softer.
They are made of a silver surface inside, which makes the light bounce inside itself and they are covered by a double layer of diffusing fabric.
Respect to the size, the larger ones produce a more diffused light than the smaller ones. So the former need a more powerful light source. On the opposite, the smaller windows give a harder light, being ideal for portraits.
With respect to their sizes:
Rectangular (2x3, 3x4) and square (2x2, 3x3):
are the most common and versatile light boxes on the market. Ideal for portrait and product photography, since they generate a soft and easy to direct lighting.
Narrow (1x3): usually used as a backlight and therefore generates very strong shadows.
Octagonal: in its small size, it is especially used in portrait photography due to the natural shape -as if it were the sun- that it generates in the eyes of the portrayed subject, playing, in general terms, the role of main light. In its larger version, it is usually used in fashion photography as filler light and gives a flatter light.
They produce a soft and especially wide illumination. Their sizes vary according to their diameters.
They are used when the scene lacks illumination. They are used both in the studio and outdoors. They control the light by bouncing it against themselves in such a way that the bounced light is reflected, thus affecting the subject or object in the scene.
There are reflectors of various shapes and sizes: 2x2 skylite, Umbrellas -Silver or White- or the folding reflectors. All of them with different diameters that make their size vary.
Depending on the effect you are looking for on the scene, we will have fabrics of different shades:
White: provides a diffuse and natural light.
Black: eliminates light, acts as a flag.
Silver: It is the one that reflects more light and at the same time, generates more contrast with the shadows.
Gold: changes the color temperature of the light source when it reflects on it resulting in warmer lighting.
