I have three flashlights to form a light array, and I don't know what other equipment is available. Can you briefly introduce soft masks and reflective umbrellas?

Soft mask, also known as flash diffuser, can soften the light emitted by flash and make photos look more natural.

Soft umbrella can diffuse light, make light softer, eliminate or weaken the shadow of light, and the subject looks soft and delicate. The closer the soft umbrella is to the bulb, the weaker and stronger the soft light effect is. Photographic equipment and soft boxes with similar functions.

Reflective umbrella is a special reflective tool with different colors. The silver umbrella does not change the color temperature of the flash; The golden umbrella can appropriately reduce the color temperature of the flash; The blue umbrella surface can appropriately improve the color temperature of the flash. In flash photography, the most commonly used reflective umbrellas are mostly white or silver.
