It is best to use a constant light source or flash for children's photography ... If what kind of constant light source should be used, what kind of flash should be used? ...

Always-on lamp, also known as constant light source, has many models to choose from: tungsten filament photographic lamp with color temperature of about 2000K/tungsten filament photographic lamp with color temperature of 3200 K-3400 K or halogen photographic lamp with color temperature of 4000-5000k/electroluminescence. This kind of lamp is simple to use, but the color temperature needs to be adjusted (filter/filter or software), which consumes a lot of electricity and has a high calorific value.

Flash lamps include ordinary umbrella lamps and professional studio flash lamps. Ordinary umbrella lamp is cheap, but its power is small and its color temperature is unstable. Room lights have high flash index, high success rate and low fever, but they are slightly more complicated to use and more expensive.

From the actual use effect, the studio flash has certain advantages: high instantaneous power, high brightness and high success rate; The power is adjustable, so you can use a variety of apertures more freely; Stable color temperature, not easy to cast color (very important); It is more comfortable to use.

However, we also consider that we are shooting children's photography. Although the flash is energy-saving, it should be used as little as possible to avoid adverse effects on children's eyes. Therefore, it is safer to use a constant light source when photographing children.
