The blue hour: photographic magic window!
I discovered the blue hour by small strokes, just by chance ... That hour really only lasts a few minutes, during which the sky turns deep blue. This time when the sun is gone and where wolf and dog merge. This time when the city's street lights. Where else in the worlds wildest, nature reasserts itself: the sounds are amplified, the trees come alive, the man hurries to return the civilized world on tiptoe under an ultramarine sky. This winter, I am partly to meet the blue hour of towns and fields. I am only at the beginning of this trip: a light, a mood to tame the tip of the lens ...
But what exactly is this famous blue hour? This brief magical moment between night and day, where the sky is deep blue hue. Not so magical as that, in reality it is a physical phenomenon called Rayleigh scattering . My main memories of being physically come down to the explosion of ammeters or strange substances contained in test tubes during Happy TP. I do not say more about it, and I return to the photo.
Photo Night: What topics photographed the blue hour?
Photographing the world right from the outset blue creates an atmosphere very peculiar, almost surreal. The blue hour is able to highlight a subject graph simple, like an old tree planted in the middle of a field.

Light the lamp and night sky blue:
In villages, some light parsimonious suddenly become much warmer, photographed at the blue hour. And as the darkness is not too pronounced, the contrast between sky and light remain manageable with a careful adjustment of brightness, the sky is not too dark, and light the lamp and not too much yellow cramées.

L "blue hour and lighting of cities at night:
In town, I find that at this time that the blue city lights are more spectacular. Yesterday I posted pictures of timbered houses lit the blue hour : night there seems more warm and cozy places seem remarkable radiate its own light. But associated with frozen neon, this strange blue hour can also express the loneliness and desolation of our cities, as in this picture taken at a gas station.

And the photo macro blue hour?
I realized only recently that I had already experienced the Macro to the blue hour. In the photo of foam below, I tried to photograph the sunset, and I made the blue hour, even if it shows a "false sun" from a spot of light residual sunset (except mistake? Is there a physicist on the web?)

What time, this time blue?
I talked about the blue hour in the evening, but this moment for the photographers are also in the morning. Depending on the season, it varies between 20 minutes and three quarter hours, and the sky is bluer and more beautiful in spring and fall. The blue hour is as fleeting as a sunset, but it has one big advantage: all those who have tried it know, it is very difficult to anticipate a sunset. We take appointments, one job at the right place at the right time, but you never know if the sun will be up to our expectations. The blue hour course known variations of intensity, depending on season, moisture content, elevation (more intense at high altitudes) , but we will have more chances to come back with some nice pictures overseas on the memory card with a sunset or sunrise.
To know the exact time begin this phenomenon, there is a simple way: Go to the site: bluehoursite.com . Simply enter your coordinates, and you get start and end of the blue hour. can hardly imagine a more simple, right?

Given the brevity of that moment, as He prepares identify in advance the photo location, position them, the right lens mount on camera, doing your presets ...
I am still very early in my experiments with the blue hour. For now, I mostly made quite contrasting images or under street lighting, incorporating areas of shade in my compositions. In these circumstances, I could make my pictures of hands (large opening with a 50 mm), between 200 and 400 ISO.Comme all photos dominant dark you will usually underexpose the image. The blue hour
also deserves to be exploited by laying low. In this case, the foot is required. And shooting in raw much better: who said long exposure noise words, especially in dark areas. It will therefore denoise image. To enhance the contrast and intensity of the blue, one can use a polarizing filter .
