Sunny days are not so good for picture taking. Photographers often need to control the natural light. I recommend to use reflectors and diffusers. Diffusers soften harsh light; reflectors, which are available in gold, silver and white surfaces, bounce the light onto a subject to fill in shadows. Gold reflectors are warmer, silver ones are cooler.
You need to move the reflector around to get the best possible light on the subject. This requires one more person as a helper or you can use a reflector holder.
