What is a camera flash?

What is a camera flash? Let's take a look at Bian Xiao's sharing today.

Flash is called flashlight in English and electronic flash in Chinese, also called high-speed flash. Flash is a photographic accessory that can emit strong light in a short time. The electronic flash lamp stores high-voltage electricity through the capacitor, and the pulse triggers the flash tube to discharge, thus completing the instantaneous flash. The color temperature of the usual electronic flash lamp is about 5500K, which is close to the color temperature in the sunlight during the day, and its luminescence property belongs to the cold light type.

The function of camera flash

1. On-site lighting: used to illuminate the site in case of insufficient light, so as to obtain correctly exposed images.

2, adjust the color temperature: photos tend to warm colors of yellow and red, adding flash can effectively adjust the color temperature, so that the color of the subject can be correctly restored.

3. Reduce the contrast: fill the dark parts appropriately to reduce the contrast of the picture.

4. Increase the depth of field: When using the flash, the aperture can be reduced accordingly, effectively increasing the depth of field.

5. Highlight the foreground: When the flash is shooting, the shutter speed is high, and the background outside the projection range of the flash cannot be displayed due to insufficient exposure, while the foreground is correctly exposed due to flash illumination, thus highlighting the foreground and eliminating background interference.

That's what Bian Xiao shared today. I hope I can help you.
