Previously I wrote about night photography in the Nikon D5300, where I mentioned about ISO sensitivity, long time exposure and exposure compensation.
The Nikon D5300 gives you many options with exposure. Basically you can take photos with 30sec time exposure, however the camera is equipped with the Bulb mode, which allows you to make much longer exposures. Have in mind, that this kind of shutter speed is possible when you have control on it. The duration of this exposure depends on the duration of keeping your finger on the shutter-release button. This option can be very useful for the completely dark places, where even the smallest light ray can come in. You won’t be able to see this very small light ray or the light dissipation by your naked eye. The Nikon D5300 will do it for you!
I prepared 4 places in my house, where I put the Bulb mode and created a very long exposure photos. Usually easier is to capture some places in the buildings, where any light is gone at all. When you are outside you always may receive some distant light rays from streetlights, some glows from remote cities or eventually some spotlights from the stars. The most darker place may be your basement, etc.
I created a base photos of this places, which started from 3,5,10 and 30s exposure time with medium ISO sensitivity from 1600 to 6400. The basic photos are almost completely dark, like you can see below. (Pic.1-4). After the basic photo based on bulb mode and nearly the highest ISO level I decided to alter those images into higher level of brightness. Thanks to the exposure compensation I received quite readable image with place, which is completely dark. Your eye isn’t capable to see any details at all. You need to wait a couple of minutes, when your eye will be able to cover some outline objects in the dark. Sometimes is nice to receive the image from place, where you are actually, but unfortunately can’t see on your own.
To emphasize your dark area details you need to take a long time exposure photo (by bulb mode) with the highest ISO (10000 – 25600) in the RAW format and then go to retouch options in your camera (RAW image processing) and set your exposure compensation from 0 EV to +1,3 – 2EV with high D-light effect. As a result you will see your place quite bright with many strange lights. Hovewer your image will be very noisy. Remember, that once you doing a photo with high ISO, next you are going to enhance every pixel by the exposure compensation you will receive a huge range of brightness. Some pixels will be nearly ark, and another will be almost white. The pixels density and their colors will indicate you the objects, light rays and dissipation of lights in the area, which you have captured.
After those alterations you can adjust your image properties also and make your image as much reliable as possible.
Every photo has been taken in Nikkor 18-55mm, 18mm (f/3.5).
