July and believe me shooting at that time of the year is really difficult. Sometimes the photos are too bright, the shadows are disturbing the entire shot and many other problems. However, the right solution to get the perfect shot in sunny days, is to shoot in 'golden hours', just before the sunset during which the daylight is soft and the photos have a warmer color.
