Time lapse clips are made of hundreds of still images shot every two or three seconds during a period of at least ten minutes, depending on the wanted length of the clip and the interval of seconds itself. Traffic passing by, clouds bubbling up, sunsets,... will offer the motion that brings life to the landscape as well as emotional and mesmerising impact. Undesired objects might often interfere in this creative proccess. Whether you are focusing a scenery in the city or in the nature, flying birds or insects will render small black dots which can ruin the experience visually. This unpredictible issue might sometimes affect a bench of images, not only one here or an other over there. When so many are concerned, retouching frame by frame will then make the workflow painfull. Remember also : from a photographic point a view, everything is set up manually. So, most of the time the light may change dramatically in short intervalls. Again specific adjusments in postproduction will be achieved in order to decrease the gaps of luminance, or even the change of contrast or color tone. Such variations are softened by the natural perception of your eyes and the interpretation by the brain. However the camera render them in a more brutal way, this is why in-depth editing, with the right tools, will apply. For the same reason, if a sequence is shot with a telelens, or from a bridge, imperceptible shaky moves will be noticable when replaying the clip. The cleaning part of time lapse making process is awaited to raise the value of the work, and to make the final video simply nicer to watch.
