Welcome to earth, folks. That place where the sun sometimes burns down to the earth so hard that we can't even step outside without sunglasses. Let's be honest here, sure it's a great light source and it keeps us warm but that sucker is powerful. That can mean awful and wonderful things for us as photographers (I'm sure you've all experienced the whole spectrum from love to hate for it). Luckily there is a way to cut down it's power a bit when we need to. The reason the sun has less power later in the day is because it has more air to cut through before it hits you. More air with dust, and water particles in it that diffuse it a bit. If you need it softened even more, why not look for some more diffusion to help you out? It might be easier than you think. Putting the sun behind tree branches is a ridiculously easy way to bring it down a notch while still keeping that gorgeous warm haze that it gives off.
