Reduce shadows based on color and reflect light back onto a subject. Silver: Perfect for black and white, product, and video photography, it brings out the highlights and contrast of images. Gold: Provides a warm, natural color that works well for indoor portraits, product photography (such as jewelry), and sunsets. White Opaque: Creates a gentle, neutral color light that is ideal for portrait photography and product photography. White Translucent: Able to soften the light source and disperse intense light. Black: To minimize reflection or block out unwanted light. Green and blue are excellent for post-production because they create a transparent background on which you can place another image behind the subject using the chroma key effect. 7-in-1 Portable Collapsible Reflector, 60x90cm Gold, silver, white, black, translucent, green, and blue
