Correct use of aperture for portrait shooting in shed

Lead: Most people take portraits with a large aperture, but taking portraits in a shed is different. Let's take a look at the correct usage of portrait aperture in the shed.

Small aperture captures details

Taking people as the main body needs 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.

▲ 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. 28mm Nikon D800+24-70mm2.8 aperture F8, shutter1160s, ISO 125, m full manual mode, RAW to JPEG.

▲ Commercial shooting cases of jewelry, accessories and makeup often require large-size output, and small apertures provide more details and good image quality. Nikon D800' s 70mm end+24-70mm2.8g. Aperture F9, shutter1/200s, ISO 100, m full manual mode, RAW to JPEG photography: 5PM studio, model: Yan 'an.

The smaller the aperture, the stronger the flash value.

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. 44mm Nikon D800+24-70mm2.8g bottom aperture F7. 1, shutter1160s, ISO 100, m full manual mode RAW to JPEG.

▲ For business needs, both products and models should be photographed clearly, and the use of small aperture is a necessary requirement. Nikon D800' s 70mm end+24-70mm2.8g. Aperture F9, shutter1/200s, ISO 160, m full manual mode, RAW to JPEG, photography: 5PM studio, model: Xu Jinglan.

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, so as to avoid the afterimage or yellow color temperature of the analog lamp due to absorption of ambient light.

2. Some high-order shed lights driven by flashlights and stability support ultra-high-speed synchronization, but the output will be limited. These are the parts that need attention before actual shooting.

3. When using soft mask and color filter, the output of the shed lamp will be weakened by the medium, so it needs to be fine-tuned to increase the output before shooting. It is best to use a professional exposure meter for confirmation.

4. The sensitivity is usually not adjusted too high, so it is recommended to use ISO 100~200 ~ 200 for better image quality.

5. The aperture size is not a certain value, which needs to be adjusted according to the focal length, shooting range and the output of the shed lamp. The commonly used aperture range is mostly around F8 ~ F 16.
