How to use slow shutter in commercial photography
How to use the slow shutter in commercial photography, the shooting of 3C products often has different requirements, not only to capture the texture or light signal of the product itself, but also to make a light effect that can set off the scientific sense of the product through light painting. In fact, these need to be presented through a small aperture and a slow shutter.
There is also an inseparable relationship between small aperture and commodity photography, that is, the realization of slow shutter. For example, the projection scene of the projector, the backlight effect of the keyboard, or other objects that are themselves illuminators must be presented through slow shutter. If you only shoot with a streamer or flash light source, it will not show the key points that should be presented, and even destroy the original texture of the goods. In addition, 3C products often need to display some flashing lights. In order to accurately capture the flashing moment of the light, the shutter that may have been tried dozens of times may not be successful. At this time, we might as well change the shooting mode, narrow the aperture and slow down the shutter speed, just like shooting lightning, so that the instantaneous light source is portrayed in the image by the slow shutter.
▲ Record the beam projected by the projector through long exposure shooting. Nikon D200+60 mm, F2.8 D, aperture F8, shutter 10s, ISO 200, M full manual mode, automatic white balance.
▲ If you only shoot with an instantaneous light source, you will not be able to present the blue backlight effect of the keyboard. Nikon D200+60 mm, F2.8 D, aperture F 10, shutter 4 seconds, ISO 100, m full manual mode, automatic white balance.
Sometimes, in order to make the product feel high-tech, we will use the method of "light painting" to make the image show different visual effects, and the dazzling light trace is unrestrained, which is also bred in the process of long-term exposure. The shooting of "light painting" is quite exhausting, and there are many variables that affect the imaging effect. Among them, the thickness of the optical track depends on the size of the aperture. Although narrowing the aperture is a common shooting setting for long exposure, depending on the appearance of the image effect, sometimes a larger aperture is used for shooting. If the light track is too thin but you don't want to open a large aperture, it is suggested that the number of point light sources can be increased to make the drawn light track more "thick". For example, as shown in the following figure 1 and Figure 2, the optical tracks of two sample photos are the results of simultaneous shooting with several LED bulbs.
▲ Using the method of "light painting", 3C products show a dazzling sense of high technology.
Nikon D200+ 17-55 mm, f 2.8g 35mm bottom, aperture F8, shutter 65s, ISO 200, M full manual mode, +0.7eV, automatic white balance.
▲ Nikon D200+60 mm, F2.8 D, aperture F 1 1, shutter 54 seconds, ISO 100, m full manual mode, automatic white balance.
