To many photographers, the morning is regarded as the nicest time to take landscape photography.
When the sun is near to the horizon, it creates a very pleasing soft shadow effect. At the same time, colour tone are less saturated when compared to other times of the day such as the midday or noon.
Interesting subjects for the morning include elements of nature. An example is the morning plants and dew droplets. Dews and droplets on leaves and grass blade create very pleasing compositions. In the case of photographing dew droplets, the close and macro focusing settings are the most appropriate.
Some plants open up in the morning such as the Morning Glory. So morning is the best time to capture their full splendour.
