LONG EXPOSURE – PATIENCE PAYS OFF

Take your time … a lot of time. When it comes to long-term exposure, it’s all about the long exposure of the sensor. Although this type of photography is also during the day possible, the recordings are for the greatest effect but preferably done at night, as the following pictures.

To perfect scan a subject for a long time and bring bright expressed, there are several factors that must be considered:

Tripod

To long to expose, without the image completely blurred, you need a stable base, possibly soil or stones, but the most effective – almost inevitably, I would say – is the use of a tripod.

Best possible there should be a heavy tripod (= tripod with three legs) . Risks of mild, less stable models: They may be easily moved by the wind or worse, it to tilt, and the exposure has to be started all over again!

Another tip: Disable necessarily the image stabilizer, since the camera otherwise would stabilize any camera shake that do not exist.

Remote release, cable release or smartphone

To give the camera enough stability and “peace”, a remote shutter release is a powerful weapon Tool. With them, the camera is triggered, without touching them. For even the smallest vibration, such as a keystroke, a long exposure image completely ruin. Meanwhile can be connected to WIFI-certified cameras and so converted to a remote release even smartphones.

Mirror Lock

High quality DSLR or system cameras have the ability to trigger the mirror or curtain in the system camera before the sensor is exposed. Also by mirrors or curtain, it is exposed to vibrations, and the image is blurred, even if only minimally. The functions “anti-shock” or “mirror lock” can be valuable here.

ISO, speed, aperture, focus

Not only accessories and a lot of time associated with this type of photography. Even camera know-how is needed here. The ISO, ie the light sensitivity of the sensor should be kept as low as possible. Because otherwise excessive noise caused by the long exposure.

Tip: ISO 100 or lower is this perfect.

The time in which the sensor is exposed, of course, should be long. The “Bulb” function allows us the exact flexibility that we need. In short, as long as I press the shutter button while is also exposed. I let the shutter button is off, the image is ready. It is to be patient and try.

The aperture that “Iris” lens is adapted to the subject. Although I Choose a large aperture (F2.8) is much light enters the camera, it may be, however, that the subject is not displayed anywhere sharp. Opt for a too small aperture (f22) the subject is captured everywhere sharp, it must be exposed any longer, which may cause noise.

 

The best adjust the aperture on the subject, and vary with the settings.

The focus should be done manually with long exposures. High-quality cameras have a built-in manual focus assist, also called “focus peaking”. Here sharp details are shown colored while operating the focus ring.

Tip: In very dark conditions, such as in the open field, a flashlight is very useful. Just on the subject light and focus.
