For achieving soft light with an exposure value of 1.5, use ISO 800-1600, wide aperture (f/2.8 or lower), and a slower shutter speed (1/30 to 1/60 seconds) indoors, with white balance set to Incandescent/Tungsten or Auto, and utilize diffusers, reflectors, and natural window light. Outdoors, set ISO 100-400, aperture f/2.8 to f/5.6 for soft backgrounds or f/8+ for more depth, shutter speed 1/200 to 1/1000 seconds, and white balance to Daylight/Shade or Auto. Enhance soft light by shooting during golden hour, using cloudy conditions, and employing portable diffusers and reflectors.
