2. Definition
denoting the photographic technique of taking a sequence of frames at set intervals to record changes that take place slowly over time. When the frames are shown at normal speed the action seems much faster.

3. Technique Option 1: Option 2: Take a video and then speed it up.
Take photos and create the movie
Option 1 Looses quality, I have not personally used it, so will not spend any time on it tonight.
Option 2 is what I will be focusing on tonight.
The equipment needed
The Process
Scouting the area – Helpful Apps
Camera Settings
Post production

4. What Equipment is needed
Tripod
Digital Camera
Shutter Release
Interval-meter
Neutral Density - ND Filter
Lens Skirt
Slider
Charged – Spare Battery – Battery Pack
ND 16 - ND 32 – Variable (Slow down Shutter Speed)
Lens Skirt (eliminate reflections)
Photoshop has a panning setting simil;ar effect to a slider – Much cheaper

5. 2 Step Process Step 1 Step 2 Take the images Process the images
Some cameras have the Time-lapse menu item, this creates the time-lapse in a movie file no need for post production – you however do not have individual photos .
Some Cameras have Interval Photos in their menu.
If your camera has neither you can get an external Interval meter that will do the same thing.
Set camera on tripod and take several images, 250 or more, using regular intervals, then, either through the camera or software produce the video. For a 10 second video at 24 frames per second – you will need 240 frames
Processing the images you can do it in Lighroom – Photoshop, or any software such as Picasa …

6. Scouting the Location
check the weather condition – Apps such as WillyWeather – BOM Weather – SunRise and Fall
The Photographer’s Ephemris – Computer app, – using Google maps you can track the location of the moon and the sun relative to the scene.
Sun Seeker App
Scouting the Location
If shooting next to the beach – make sure you check the tides (Willy Weather)

7. Camera Settings Charge your battery
Shoot in Aperture priority (Or Manual)
Shoot in speeds of 1/50 sec or slower
Shoot in RAW
Cover the viewfinder of the camera to reduce flickering video
If you have a battery pack put it on for very long time-lapses – you can then change batteries during the shoot without interruptions (Careful not to move the camera)
Faster speeds will create choppy videos. (Use ND to reduce the speed)
Raw when high dynamic range is high
Use a wide aperture – Wider than f/8 – reduces the visibility of any dust that may be on the sensor
Choose Small Raw (Canon) or ‘Crop Mode” on a full frame to reduce the size of the Raw files

8. Camera Settings Fully Manual Aperture Priority & Auto White Balance
For scenes where the level of light is constant, set Focus, White Balance, Exposure and ISA to Manual
Aperture Priority & Auto White Balance
For scenes where the level of light is changing, such as sunsets and sunrise, in these case set the Focus to Manual.
Manual mode, you don’t want breif changinf conditions to influence the images your video will end up with different tonalities.

9. How many frames per second is good for time lapse?
You want 10 seconds of compiled cloud footage to be shown at 25 frames per second. This will require [ 10 x 25 = 250 ] 250 frames to captured. You can see that the clouds are moving moderately fast and you want a nice smooth video. You decide to shoot at a 2 second interval.

10. Choosing an Interval Think of the event that you are shooting
Try and guess how long it will take
For a 10 sec clip at 24 frames per sec
240 1 sec intervals = 4 minutes
240 5 sec intervals = 20 minutes
Consider your exposure time
Tide coming in – stars – sunrise - Clouds

11. Post Using Lightroom and Photoshop By Mark Galer
Input photos into Lightroom.
Edit the first image until happy,
Crop to a 16:9 ratio – video ready
Sync the rest, so they all look the same
Review 1st Image one in the middle and Last image (ensure lighting changes have synced well)
