The pilgrimage to El Rocío in Andalusia is the most exotic festival on the European continent, one of the largest pilgrimages in the world, and the weather during Pentecost is usually sunny and hot. What it certainly has in abundance is atmosphere. The question is, how do you best capture “atmosphere” in a photo?
The general rule is this: the more light you allow into your photos, the more atmospheric they will become. Make light your main subject and then look for an interesting scene, not the other way around.
Strongly backlit settings are what to look for. When the sun is low, don’t turn your back on it. In fact, never turn your back on the sun. It really pays off to have the sun in sight because it will backlight or sidelight the situation you are photographing.
There are a few things to keep in mind. The rays and spots of light that show up on your photos when photographing against the light are caused by tiny specks of dirt or dust on (and in) your lens. The only way to avoid them is to clean it obsessively.
And, when allowing the sun directly into your photo, you need to overexpose by one or two stops to adjust your camera settings.
