Use of focused lighting (Spotlights)

Focused light is frequently used to illuminate dead nature subjects or to focus bright light on small areas where it is not possible to bring regular light sources close to be effective. This concentrated illumination gives accurate light that can be directed to where we want.

In themes of dead nature, shadows play an important role in building the overall composition of the image.
An interesting picture can be obtained from trivial topics, by casting strong and large shadows for its various elements. See picture (12), where the dead nature in it was given a great effect with concentrated lighting that created strong shadows.

interior photography

It is rare that sufficient natural light is available inside buildings for a suitable exposure, and this light is rarely evenly distributed to give a good picture, so indoor photography with artificial lighting gives better results.
Usually, the source of natural light is in a room, from one of its sides, making part of it well-lit and the remaining parts in deep shadow.

Despite this, there are cases where the natural lighting indoors is uneven and spotty, but it is perfectly suitable for photography, especially if it is intended to photograph a corner of the room and not the whole room. And the two pictures (13 and 14) are good examples of pictures taken indoors with natural light.
In photo 13 the lighting is evenly distributed, while photo 14 is speckled. This spotting was used to create
A certain atmosphere appropriate to the topic.
