The Opening And Flicker

The Opening And Flicker

If you use a small aperture, such as f / 8 or above, the shutter will move much, from all open during the “waiting” to the value set at the time of shooting. More so high is the value of f, the greater will be this movement. As the motor that adjusts the shutter is particularly accurate, it will never be perfect, so there may be slight differences between one shot and the other in terms of opening. Resulting in differences in brightness or fire, due to additional “flicker” in the final video.

To overcome this problem, you need to choose a relatively open aperture to minimize the engine work shutter. The wider the aperture the better the “solution” to this problem http://akusaraprosound.com. Normally, however, you can get a good result not going beyond f / 8.

Shutter and or flicker

Another type of flicker to be considered is that due to the shutter: the shorter the time the more the risk of flicker increases. Obviously with too long we risk to have moved in the photo: a problem because in the end, in video editing, camera shake should be sufficiently disguised to our eye.

Most photographers timelaspe recommend using at least 1 / 50s for not flicker even if there are photographers that go up to 1 / 100s.

Eye on the time between frames: another cause of flicker is too much difference in terms of time between poses. Each situation needs different timings of course: the growth of a plant, set with long intervals, will not be one “flicker” as opposed to a street full of people who will require time to avoid short “jumps” too marked.

Pay attention to the speed of your memory: do not set a time timelapse too short and avoid saving in RAW. Surely you do not care the extreme manageability of RAW (we’re talking hundreds of photos), so JPEG is more than enough. JPEG, being much smaller than RAW, will further decrease the waiting time between shots, reaching a top speed shutter of your camera (which will be between 3 and 6 fps).

The optimum exposure.

Summarizing the written above: use a slow shutter speed and aperture wide.
Too bad that this combination Could be “lethal” for times of strong lighting (noon) resulting photo overexposed or burned.
