June 21st is summer solstice, the day of the year when dawn and dusk linger the longest, which makes it the best time to make use of the "golden hours".
There are two golden hours every day of the year. The morning hour starts just before sunrise; the evening is the last hour before sunset.
What makes these times of day, sometimes referred to as "magic hours", so exceptional? For the most part it's the light that becomes richer and more vivid the further we are from midday.

Entire books and websites have been devoted to photos taken at these hours.
The luminous Riviera is the perfect place to try taking pictures at these moments of day. If you need some inspiration do a Google image search for "photography golden hour".
