Time laps

A sequence of still images that when you play back at 24 frames a second or 30 frames a second speed up the real world and it allows you to see the world in a way that you wouldn't usually see it.

A series of pictures need to be taken for example a picture after every 5 seconds. That can be adjusted according to how fast the movement is on the scene or how slow the movement is on the scene.

This means that of your taking a photograph after every 5 seconds you will have 12 pictures in a minute and 24 pictures in two minutes. This also means that 2 minutes of the real world will become 1 second in the video.

Anything can be photographed with really slow movement. For example the sky. It looks still when you're just standing there but when you will see it in the time lapse sequence you will see that it is actually moving.

The photographs can be taken through a intervalometer. This is useful because the photographer does not need to press the shutter themselves after every 5 seconds for hours in order to take the sequence of photographs. A tripod is also really important for this process in order to get the exactly same framing in every shot taken.

Manual camera setting is essential. F9 and ISO 100. The white balance needs to be fixed because we obviously do not want it to get changed in every single shot that we take. Manual focusing as well because we don't want the camera to start focusing itself on different things in the frame during the process. If you're shooting on RAW, the memory card will most probably get full really fast and the photographs will not actually be printed on paper. They will get turned into a full HD high definition video which is why we do not actually need the full 10 million pixels that a camera can produce. It is better to set the camera on the 'S RAW' option which is enough to produce a good quality video.

After that, those photographs can be processed on Lightroom. After importing all of the photographs we can go to the develop option and start editing one photograph. First thing that you can start with is cropping the frame because obviously it is meant to be for a video. If you go on the crop option on Lightroom and click on the 'original' option a drop down list will appear where 'Enter custom' needs to be clicked. The aspect ratio that needs to be put in for a video is 16.000 x 9. All other essential changed can be changed in the way you like the photograph.

Following are a few things that can be adjusted on Lightroom if needed to:

Straighten the image - Angle: this can be used for example when a landscape is being photographed and the straight line that you usually see in it is missing.
The exposure - Increase or decrease the way you like it.
Recovery option - This is usually nice to bring the sky back.
Fill light - To open up the shadows.
Contrast - Can be changed if the photograph looks flat.

Vibrance - For the colours in a photograph.
Saturation - Can be changed if needed.
White Balance - This can be used when there is a drift of colours because of the white balance not being set right. (Daylight for a landscape looks more realistic)
The graduated filter can be used to adjust parts of the photograph when not the whole image needs to be adjusted, just a part.

To do the same adjustments on all of the photographs that have been done on one, you first need to press 'control A' or 'command A' on a Mac and all of the photographs will be selected. Than you need to click on the 'Sync' button and clock on 'Check all' and Synchronise. All the photos will have the same settings as the first one.

Than next to make the video you need to go to slideshow. When looking through the presents of Lightroom you will not find any that will say time lapse video. But what you can do is go to the overlays option and selecting the minimum time that can be set on Lightroom (0.1). This will make a video that shows 10 frames per second. But it is always better to do 24 frames a second.

Another way that I would usually do it is adding the photographs on Final Cut Pro or on Adobe Premier Pro and just speed the time.
