Night photography.

 As we already know, night photography is focused on the recreation of lights in contrast with the darkness of the night.
I went to the street to take some pictures as a example and experiment with it:

                                                                                                                                                                             

 This first example of night photography I took a shot of a shop, trying to catch focused and defined the lights on it's door.
As we can see on the first one, I had the exposure open too long (exposure 0.0, ISO800,) what made the camera absorb too much light, making visible the street, illuminated a street light, but burning the blue lights of the shop, which were my first objective.

As this image wasn't successful I took the picture again giving some zoom to it, and also changing the settings of the camera:  I used a lower Iso number and  I dropped the exposure time as well(1/50 F4.4 exposure-2.0, ISO400, WB AUTO) taking a darker shot, but with all the illuminated areas clear, defined and with a nice bright color.

Then I started to play with the lights, the first picture I took I zoomed into some lights and blurred them. I used a short exposition time (-1.3), to keep the shape and the intense colours of the circles, and a high Iso number(800), to keep the shot bright.

Then I did just the oposite:I opened the exposition to +1.0 and dropped the ISO number to 200 to keep the image dark. Because the shot was long I could move a little my camera and move the lights, if you get good on it you can draw with the light just making the shot whit a very long exposure time, in a dark enough place.

This two pictures were taken in the night with the illumination of  light bulbs. To keep the impression of the night I used a low ISO number (200) and I left the exposition on 0.0 . Because it was enough illumination I could take a  not long shot and the person walking is mostly well defined, and the red colour appears dark and intense.
