Can I turn on the flash when taking pictures of children?

I still remember when I just gave birth to a baby, I looked at the newborn baby every day, with a smile and a little gesture, and I felt so cute. I really want to take pictures! But! I wonder if taking pictures will be bad for my baby's eyes! Especially when you go to the studio to take art photos, there are more than N photos at a time, and it is inevitable that you will turn on the flash. The baby is so small, can the flash be harmful to the eyes?

"The harm of light to the human eye mainly depends on

The wavelength, intensity, time and distance of irradiation light. "

The flash of mobile phone or camera is mainly xenon lamp or LED lamp, whose spectrum is similar to that of sunlight, and naturally it also contains bands similar to sunlight that will cause harm to eyes, such as ultraviolet rays and blue light.

The luminous intensity of a small professional flashlight is equivalent to100W100W tungsten lamp. Although it sounds terrible in numerical terms, it is actually not as fierce as the daily sunshine. Moreover, the click flash irradiation time is very short, and the time is usually

Generally, when taking pictures of children, the photographer will also keep a distance of at least 1m from the children, so the damage of this part of the flash does not need to be worried by the treasure mothers.

However, it is important to draw the key points here. Don't be too close to the baby when taking pictures of the younger baby. The closer the distance, the greater the damage. Therefore, it is recommended that infants within 6 months avoid using electronic flash to take pictures, and it is best to use natural light sources, or use side light and backlight, and do not let strong light directly illuminate the child's face.

When encountering strong light, people's pupils will contract reflexively, just like narrowing the aperture of a camera, reducing the amount of light entering the eyes, thus protecting the eyes from strong light. The staring function of such a small baby's eyes is not perfect, and he is not interested in taking pictures. He likes to roll his eyes and look around. It's almost impossible for him to stare at the camera and flash all the time. Flash for daily photography is unlikely to damage the baby's eyes unless it is illuminated for a long time.

"So, the damage of flash to children's eyes is actually not so terrible."

The brightness of the flash is actually not high. People think that the flash is too bright because the surrounding environment is too dark when it is used, and the contrast between light and shade creates this illusion. However, even if the flash is unlikely to damage the baby's eyes, this strong light will still cause some discomfort. Therefore, it is suggested to minimize the number of shots, use natural light as much as possible when shooting children, or aim the flash at the ceiling or the wall behind or on the side, so that the light is soft and won't hurt the eyes.
