Application of Small Aperture in Portrait Business Studio

Lead: Simply taking "people" as the main shooting subject, we also need to take into account the overall shape, expression, emotion and even physical performance. At this time, the deep and long depth of field created by the small aperture can be vividly recorded in the image. Therefore, when shooting in the shed, there are often more opportunities to use a small aperture than a large aperture. Instead, the photographer grasps the shed light, such as direction, texture and color. Come and have a look!

▲ With the help of depth of field and accurate illumination, the texture of walls and light can be recorded completely and delicately, which also adds more interesting details to the image.

▲ Commercial shooting cases of jewelry, accessories and makeup often require large-size output, and small apertures provide more details and good image quality.

More interestingly, when shooting in the shed, the aperture and shutter speed should be viewed separately, and even in many cases the shutter speed can only be adjusted below the synchronous speed of the flash shutter. The main reason is that the professional shed light in the studio is an instantaneous light source, and the exposure work is usually completed at the moment when the shutter is fully opened. It is also because the time is very short, as long as the photographer's action is not big or fast, he can basically complete the condensation action. Therefore, the aperture size does not need to consider the shutter speed, but depends on the flash output, that is, the smaller the aperture setting, the stronger the flash output that needs to be set. Of course, if there are shed lamp accessories such as soft light cover, tracing paper and reflective umbrella, it is necessary to appropriately adjust and enhance the output of the flash lamp. In order to accurately confirm the output value of each shed light, it is best to work with a professional exposure meter that can measure instantaneous light for more accurate lighting.

▲ When shooting in the shed, the three-dimensional space is usually composed of light and shadow, not the shallow depth of field commonly used by players.

▲ For business needs, both products and models should be photographed clearly, and the use of small aperture is a necessary requirement.

Precautions for shooting

1. When shooting in the shed, be careful that the shutter speed should not exceed the maximum shutter synchronization speed supported by the shed lamp, but it should not be too slow to avoid the afterimage or the yellow color temperature of the simulated lamp due to the absorption of ambient light.

2. Although some high-order shed lamps driven by flashlights and stability support ultra-high speed synchronization, their output will be limited. These are the parts that need to be paid attention to before the actual shooting.

3. When soft mask and color filter are used, the output of shed lamp will be weakened by medium. Fine-tuning is needed before shooting to increase output. It is best to use a professional exposure meter for confirmation.

4. The sensitivity is usually not adjusted too high. It is suggested to use ISO 100~200 ~ 200 sensitivity value to obtain better image quality.

5. The aperture size has no certain value, which needs to be adjusted according to the focal length, shooting range and the output of the shed lamp. The most commonly used aperture range is around F8 ~ F 16.
