Selection skills of still life photography lamp group

The key to choosing a flash is to determine what kind of flash you need and how many functions it has. According to the energy (brightness), the flash lamp can be divided into three categories when the electrodes at both ends of the flash tube are instantaneously discharged:

1. High voltage flash lamp with voltage above 2500 volts.

This kind of lamp has the advantages of large output energy and high brightness, which can meet the needs of large scenes and long-distance shooting. The disadvantage is that it is bulky and inconvenient to carry. Therefore, apart from the special needs of professional photographers, amateur photographers should not choose.

2.500 volt flash

This kind of lamp has moderate output power, which can generally meet the needs of shooting light, and it is convenient to carry, comprehensive in performance, and has many models and enough choices. It is one of the practical lamps for photographers and enthusiasts.

Small low-voltage flash lamp below 3.500 volts

This kind of lamp is small in size, light in weight, low in power consumption, cheap in price and diverse in types, which is very suitable for professional and amateur photographers.

Field fill light

The main function of the flash is to illuminate the scene in the case of insufficient light and obtain the correctly exposed image. Most digital cameras have an automatic flash option. When there is insufficient light in the scene, the flash will automatically pop up and flash.

Increase shutter speed

Many times we use a flash. It is not because the light is not enough to expose correctly, but by increasing the shutter speed to achieve the purpose of curing the dynamic image. For example, if you want to take pictures of water droplets or moving portraits, if you expose them according to ordinary photometric values, the images will be blurred and not clear enough, and these images can be solidified by flash.

Increase depth of field

We know that the depth of field effect of an image is closely related to the aperture size. Generally, the larger the aperture, the smaller the depth of field. Moreover, the aperture is small and the depth of field is large. Using this principle, you can actually use a flash to increase the depth of field.

Sometimes, due to the limitation of light in the scene, we have to use a large aperture to shoot, but the depth of field is insufficient, and when using the flash. We can reduce the aperture accordingly. Effectively increase the depth of field.

Highlight potential customers

Many times we will find it on the shooting scene. The effect of the background is not ideal or not what we want at all. At this time, we can try to use flash to eliminate the background, because when shooting with flash, the shutter speed is high, and the background outside the projection range of flash will not be displayed because of insufficient exposure. Due to the flash lighting, the foreground is correctly exposed, thus highlighting the foreground and eliminating background interference.

Reduce contrast

Another common use of flash lamps is backlighting. When shooting, it is common that the contrast of light in the scene is too large (such as portraits in backlight). Because the brightness range that CCD or film can express is limited, some image details will be lost in the scene with excessive contrast, whether exposed to light or darkness.

In this case, the best way is to fill the light in the dark to reduce the contrast of the picture. Of course, you can also reduce the light in the bright part. Flash is the most powerful weapon in this situation! The specific method is very simple. Just turn on the flash and let it illuminate the dark part when shooting, and the effect is generally good.

Adjust color temperature

When photographed under electric light, photos tend to appear warm yellow and red tones, because the color temperature in tungsten lamp is low, and the flash can effectively adjust the color temperature, thus correctly restoring the color of the subject.

I suggest you buy a flash. I'm a photographer from Shang photo studio. I usually see that guests choose to buy two constant-light still lifes first, but it is difficult to get good results! I suggest you buy a flash of about 200W, Ness's is good and cost-effective!
